In an effort to reverse the alarming increase in roadway fatalities over the past year, the FHWA recently embarked upon a new national initiative called "Road to Zero." This effort, led by the National Safety Council, with the help of FHWA, NHTSA, and FMCSA, has the ambitious goal of eliminating roadway fatalities within the next 30 years.
I am particularly excited to see that Road to Zero includes partners from a wide range of disciplines such as transportation safety, urban planning, public health, and information technology. Road to Zero promotes proven lifesaving strategies with an emphasis on cross-discipline activities. The coalition will also lead the development of a new scenario-based roadmap which will help achieve zero traffic deaths using evidence-based strategies and a systematic approach to eliminating risks. An important element of this undertaking is developing a zero-traffic-deaths scenario that incorporates the strategic deployment of self-driving cars, which will reveal needs that haven't been considered and create a planning tool for policymakers and traffic safety organizations. The Road to Zero offers an exciting new way to work with colleagues across diverse disciplines on our mutual goal of driving the number of deaths on our roads to zero.
Sharing information on successful safety practices is a key component of Road to Zero. I'm happy to note that this issue of the Safety Compass is full of information on these kinds of practices. For example, data-driven safety analysis is taking a leading role in identifying which roadways aren't performing as they should and how they can be improved (page 3). Effective countermeasures such as road diets are being used in Honolulu, HI, as a tool to improve safety and livability as part of its Complete Streets initiative (page 7). And of course, we have issued a treasure trove of new guidance and information products on topics such as State Highway Safety Plans (p. 10), speed management (p. 16), and systemic safety implementation (p. 16), to name a few.
I encourage you to get involved and learn more about Road to Zero in the coming weeks and months. Read more at the NSC Road to Zero website www.nsc.org/learn/NSC-Initiatives/Pages/The-Road-to-Zero.aspx, and follow @RoadToZeroUS on Twitter.

The Highway Safety Improvement Program (HSIP) is a core Federal-aid program which aims to achieve a significant reduction in fatalities and serious injuries on all public roads. Under the Moving Ahead for Progress in the 21st Century Act (MAP-21), Congress authorized approximately $2.4 billion per year to help States achieve this goal through the implementation of highway safety improvement projects. This is nearly double the amount that was authorized under the previous legislative act. Together, the States obligated nearly $3.9 billion for over 4,100 highway safety improvement projects in 2015.
These highway safety improvement projects come in all shapes and sizes. Some are high-value reconstruction projects, while others consist of low-cost countermeasure installations across multiple sites. The 2015 HSIP National Summary Report provides an aggregate summary of the type and cost of projects across all States. Highlights of the States' 2015 HSIP implementation efforts are provided below.
The number and cost of HSIP projects has continued to increase from 1,684 projects with a total cost of $1.61B in 2009 to 4,188 projects with a total cost of $3.90B in 2015. Over the past 7 years, States obligated $16.6 billion for more than 19,000 highway safety improvement projects.

Data-Driven Safety Analysis made great strides under Every Day Counts 3 (EDC-3) initiative, with more than 40 States applying DDSA on one or more projects in the areas of planning, alternatives analysis, design, and operations. Interest in DDSA has remained so high, that it was selected as one of the innovations to continue under EDC-4. Now that States have tried it, many State DOTs and local agencies have set their sights on integrating DDSA into their policies and procedures throughout their respective project development processes.
One of the areas in which we've seen progress in applying DDSA is planning. Predictive and systemic analysis tools can be applied early in the project development process to help identify which roadways aren't performing as they should, determine the scope and need of potential projects, and prioritize them.
For example, the Ohio Department of Transportation (ODOT) is incorporating data-driven safety analysis into its project development process so that safety will be considered in all project planning - from minor resurfacing to major construction projects. The agency created safety-integrated project maps that identify priority locations where safety improvements should be considered on projects that overlap these areas.
The Colorado Department of Transportation is another State that's performing a safety analysis of all its projects as part of a transportation systems management and operations (TSM&O) evaluation. This evaluation process compares existing safety performance of a project location with how that particular roadway was expected to perform. Projects with a high potential for safety improvement are then scoped accordingly to address the identified safety issues.
The good news is that identifying roadway sites with the greatest potential for safety improvement doesn't have to be overly complicated. In fact, many State and local agencies have accomplished this by implementing the systemic approach to highway safety. For those not familiar with the systemic approach, it's really similar to how doctors provide care to their patients. First they inquire about your family health history, your personal health history, and your behavior (including exercise, diet, etc.). They then use this information to assess your risk of developing certain diseases and proactively work to minimize that risk before major issues develop later in life.
Similarly, we can perform "health assessments" on our roadway systems using these steps:
We can then proactively treat locations that surpass the threshold for crash risk with low-cost countermeasures.
For more information on the systemic approach, visit http://safety.fhwa.dot.gov/systemic/. For DDSA-related training and technical assistance please contact Jerry Roche at firstname.lastname@example.org or John McFadden at email@example.com.

Transportation professionals know that data tells a story and, for decades, FHWA has collected data that tells important stories about our Nation's travel needs–from where and how old the country's oldest bridges are to how many teenagers are getting drivers licenses each year. The safety story is also extremely important, especially now as data reveal that crashes and fatalities are rising. Data about our roadways tells stories that have widespread ramifications, and safety professionals can start using that data to share relevant information about our roadways with the public.
FHWA's Office of Public Affairs has been working to develop a series of engaging graphics that help convey important messages about trends and other information that the public finds interesting or relevant. The effort started in 2014 when the staff was trying to figure out what would be appropriate to post on the agency's new Facebook page.
"We started trying to pick things out to share, and we experimented with what the data world calls 'data visualization'–which is just a simplified trend analysis that the average person might find interesting," explained Doug Hecox of FHWA's Office of Public Affairs. The result?
"We're reaching thousands of people. We're telling more Americans about their road system, and they are intrigued. The results from our infographics are outpacing anything we've ever done in informing the public," Hecox added. "It's not even comparable," he added.
The FHWA public affairs team works closely with the Office of Policy to sift through reams of FHWA data to identify interesting and educational facts about our infrastructure and driving trends to showcase the changing nature of our transportation system and driving habits to the American public. They have found that, the more they can make it possible for viewers to interact with the data, the more fun it is, "like the Google doodle," Hecox noted, adding that the staff is exploring the possibility of developing more interactive infographics in the coming year.
To date, their work has yielded several safety-related infographics. For example, one addresses the importance of nighttime visibility for trick-or-treaters on Halloween (see image below). Another showcases the rising instances of work zone fatalities as a means of drawing attention to the need for drivers to be extra careful when traveling through active work zones. A third uses a chart to point out that, ever since the first person in the U.S. was killed by an automobile in 1899, safety improvements have helped to reduce the fatality rate despite steady increases in VMT over the years.
FHWA's infographics are important for many reasons, not least of which is because, once a user's interest is caught, the person will typically stay on the website looking for other "tidbits" of interesting information. The infographics also drive traffic to the agency's website, Twitter feed and other social media channels, making FHWA an information "destination." This allows FHWA to support its educational goal of helping the public understand the role its transportation network plays and other important truths, like who drives on the Nation's roadways, where the money for infrastructure is spent, and how the transportation system acts as the backbone of our economy.
The next step is to think about how these social media can be used in schools, perhaps in conjunction with STEM curriculum. As an extension of that, Hecox urged data and statistical staff at transportation agencies to work with their public relations and communications staff to identify trends or stories that the public needs to know about when it comes to safety. The challenge, he added, is to keep the story told by the data fresh, timely and original.
Do you have ideas or know of data trends that might lend themselves to safety-related infographics that will capture people's attention and educate them about the importance of roadway safety? We invite you to share your thought by contacting Doug Hecox at firstname.lastname@example.org.

Want to share your love for Road Diets? Across the Nation, transportation specialists, travelers, and road practitioners have been posting photos online using the hashtag "#RoadDiets" to promote their enthusiasm for this effective road reconfiguration technique. Now, it's your turn. Post a photo today and join the movement!
The goal of the Selfie Campaign is to raise awareness of a Road Diets to the general public and to promote the effectiveness of these successful road reconfigurations. This is one in a series of campaigns, led by the FHWA Office of Safety, to encourage agencies to institutionalize Road Diets as a safety solution.
Almost half of the States in the country have formally adopted policies to implement Road Diets to ease congestion and improve safety on busy corridors. Most of the remaining States are in the development, demonstration, and assessment stages and are moving toward establishing Road Diets as a standard agency practice. This comes as no surprise; when properly planned and tested, Road Diets work!
Road Diets are a valuable tool in the transportation engineer's toolbox and offer a variety of configurations that can be adapted to serve a community's specific needs. Unfortunately, those most directly affected by the road reconfigurations–members of the public–are largely unaware of what Road Diets are or the extensive benefits they can offer.
The goal of Road Diets is to improve safety and livability at a low cost while significantly reducing crashes and making commuting safer for all road users. The term "Road Diets" is not well known, and this campaign is an opportunity to educate the public about the many benefits, allay concerns about the possible negative impacts, and correct misinformation.
It's easy! Here's how it works:
I look forward to seeing your post! Remember, be safe when you take that selfie!
To learn more about use cases and scenarios for Road Diets, download the Road Diet Case Studies Guide.

The Department of Transportation Services (DTS) of the City & County of Honolulu is working hard to implement Complete Streets policies by applying new guidelines for maintenance and paving projects and by identifying projects that can be used to promote Complete Street designs to improve specific locations. One element of this effort involves expanding the application of Road Diets as a means of supporting the agency's vision for a comprehensive, integrated network of streets that are safe and convenient for all people whether traveling by foot, bicycle, transit, or automobile, and regardless of age or ability.
Since the Honolulu City Council adopted a Complete Streets policy and passed related ordinances in 2012, DTS has established a multi-disciplinary Complete Streets Team, headed by a newly established Complete Streets Program Administrator. To date, the team has conducted in-depth studies on 16 locations where it is considering implementing a variety of different treatments to promote a more complete road network. Of sites examined, a quarter includes recommendations for Road Diet applications, and several others recommend lane narrowing as a way to make room for pedestrian areas, bike lanes, or additional parking.
Going forward, the Complete Streets Team will continue to have great opportunities to implement Complete Streets principles through Honolulu's ongoing street rehabilitation efforts. Previously, there had been a limited amount of systematic efforts to look at optimizing multimodal roadway use through changes within the right-of-way. As a part of this new review process, roadways will be identified for needed changes to sidewalks and areas beyond the existing travelway to benefit all users.
"The road diet is seen as the perfect tool to address overbuilt travelways that suffer from vehicular speeding," said Mike Packard, the Complete Streets Program Administrator for the City and County of Honolulu. "They also provide a safer facility for pedestrians, bicyclists, and vehicles alike."

High quality data and reliable analytical methods are the foundation of data-driven decision making. The new Reliability of Roadway Safety Management Methods series includes four information guides that identify opportunities and the latest tools to employ more reliable, state-of-the-art methods to support decisions throughout the roadway safety management process. The following information guides cover four specific components of the roadway safety management processes:
The roadway safety management process is an integral part of the project development process. The results provide information for system planning, project planning, design and construction, and operations and maintenance of a transportation system. Each guide introduces the roadway safety management process and provides an overview of the featured step.
The purpose of the Reliability of Roadway Safety Management Methods series is to demonstrate the value of more reliable methods in these activities, and demonstrate limitations of traditional (less reliable) methods. Each guide provides examples to illustrate the application of the various methods and highlights differences in results among the more reliable and less reliable methods. The guides conclude with sections concerning data requirements and tools and resources. The following is a brief summary of the four guides included in the Reliability of Roadway Safety Management Methods series:
Network Screening: Network screening is the process of analyzing the network to identify sites for further investigation. The Network Screening guide provides an overview of various performance measures for conducting network screening, including crash frequency, crash rate, equivalent property damage only, critical rate, level of service of safety, Empirical Bayes expected crashes, and Empirical Bayes expected excess crashes. The guide provides a discussion of the associated strengths and limitations for each performance measure and focuses on opportunities to employ more reliable performance measures to overcome potential limitations. (More reliable measures account for potential bias due to regression-to-the-mean, changes in traffic volume, the nonlinear relationship between crash frequency and traffic volume, and differences in crash severity.)
Diagnosis: Diagnosis is the process of further investigating sites identified in a network screening for existing and potential safety issues. The focus of the Diagnosis guide is applying more reliable diagnosis methods to understand the nature of reported crashes and identify factors that contribute to crashes. It describes how thorough diagnosis supports targeted countermeasure selection. The guide provides an overview of various methods to enhance the diagnosis process, including the Haddon Matrix (a framework for understanding the origins of injury problems and for identifying countermeasures to address those problems), test of proportions, and analysis of time trends. For each method, the guide provides a general discussion and examples focusing on opportunities to enhance the diagnosis process.
Countermeasure Selection: Countermeasure selection is the process of assessing ways to address or mitigate the underlying safety issues identified in diagnosis. The Countermeasure Selection guide focuses on the use of more reliable data-driven countermeasure selection methods. It provides an overview of various methods for selecting countermeasures, including the Haddon Matrix, data-driven crash-based methods (e.g., expected crashes and crash modification factors), and data-driven behavior-based methods. For each method, the guide provides a discussion of the opportunities to enhance the countermeasure selection process.
More reliable methods such as the Haddon Matrix help safety professional's account for factors that contribute to crashes and will generally lead to the selection of targeted, effective, and defensible countermeasures. More reliable methods, such as the use of CMFs and the associated standard error, help to quantify and consider the range of potential safety effects for a contemplated countermeasure.
|Period||Human Factors||Vehicle Factors||Roadway Factors|
|Before (causes of hazardous situation)||Poor vision, slow reaction time, alcohol, speeding, risk taking||Failed brakes, missing lights, lack of warning systems||Narrow shoulders, limited pavement markings, poorly timed signals|
|During (causes of crash severity)||Failure to use occupant restraints||Malfunctioning safety belts, poorly engineered airbags||Non-breakaway sign supports|
|After (factors of crash outcomes)||Age (high susceptibility), alcohol||Poorly designed fuel tanks||Poor emergency communication systems|
Safety Effectiveness Evaluation: Safety effectiveness evaluation is the process of estimating the safety impacts of implemented projects, which provides a critical feedback link for future decisions. The Safety Effectiveness Evaluation guide provides an overview of various methods for conducting observational before-after studies, including simple before-after, before-after with linear and nonlinear traffic volume correction, before-after with comparison group, and Empirical Bayes (EB) before-after. For each method, the guide provides a discussion of the associated strengths and limitations, focusing on opportunities to employ more reliable methods to overcome potential limitations. More reliable methods account for potential bias due to regression-to-the-mean, changes in traffic volume, the nonlinear relationship between crash frequency and traffic volume, and general temporal effects.
The target audience for the Reliability of Roadway Safety Management Methods series includes data analysts, project managers, and program managers involved in projects that impact highway safety. Each guide provides information that will enable users to identify and adopt more reliable methods for roadway safety management. These guides will help users to:

It has been said that "change is not only likely, it's inevitable." In the area of transportation safety we know this is true. We regularly see changes in leadership, legislation, regulations, policy, personnel, roles and responsibilities and more. These are opportune times to familiarize new stakeholders with the Strategic Highway Safety Plan (SHSP), particularly transportation leaders and newcomers to the SHSP process. Two new resources from the Office of Safety will help bring new stakeholders up to speed on the SHSP. To learn more, take a look at the SHSP Quick Reference Guide and the SHSP Leadership Briefing Packet.
SHSP Quick Reference Guide: This guide is designed to provide professionals, especially those who are new to the SHSP process, with quick and easy access to the information they need to successfully understand and manage an SHSP. It both provides an overview of the basic elements and requirements of an SHSP and offers helpful resources and links where practitioners can go to learn more. The guide also contains practical tips and noteworthy practices from professionals involved in the daily operations of the SHSP process.
Leading the Way to a Safer Transportation System: SHSP Leadership Briefing Packet: Leaders are critical to the success of any traffic safety effort, but nowhere can that leadership have such an immediate and lasting impact as through the State's SHSP. The purpose of this packet is to brief leaders on the importance of the SHSP, its role as part of the Highway Safety Improvement Program (HSIP), and why their involvement in this effort is crucial. The packet is particularly useful as part of a larger briefing on safety or as a way to gain more support for the SHSP, such as after passage of major transportation legislation or when there are changes in a State's administration.

Task Force 13 is a group of concerned and experienced representatives from industry, academia, and State and Federal transportation departments who are tasked with developing, recommending, and promoting standards and specifications for bridge and road hardware. Task Force 13 has met twice a year since 1969 and is the only remaining Task Force organized under the AASHTO-AGC-ARTBA Joint Committee, Subcommittee of New Materials and Technologies. This group is responsible for maintaining a treasury of drawings of roadside safety hardware, many of which used to be part of the AASHTO Roadside Design Guide. The drawings encompass both generic and proprietary roadside hardware and may be used by highway agencies, engineering consultants, and others who need accurate information on crashworthy devices.
The group maintains a series of web pages with online guides designed to support transportation professionals in selecting the appropriate hardware and devices for their needs:
While most drawings currently in the guides show devices that have been crash tested to NCHRP Report 350, hardware meeting the AASHTO Manual for Assessing Safety Hardware is added after every Task Force meeting.
The Task Force accomplishes its mission through subcommittees that focus on the five guides listed above as well as Work Zone Devices, Certification of Crash Test Laboratories / Computational Mechanics, and Delineation. The Task Force also meets as a whole to discuss their on-line publications and improvements to the website.

The FHWA Office of Safety and the Office of Planning, Environment, and Realty have jointly developed a guidebook entitled Building Links to Improve Safety: How Safety and Transportation Planning Practitioners Work Together. This guide book is designed to provide a toolkit of strategies for State DOTs, FHWA Division offices, metropolitan planning organizations (MPO), and local and tribal agencies to integrate the safety and transportation planning processes.
The publication is written for both planners and safety practitioners and gives each group an introduction to the other's planning processes, high-lighting areas of overlap where opportunities exist to collaborate to improve safety and mobility. The guide offers strategies and practices based on questionnaires and interviews conducted with transportation planners and safety specialists in five States that have a successful track record of linking transportation and safety planning efforts (Arizona, California, Iowa, Oregon, and Virginia). It also provides actionable steps for planners, safety specialists, and the broader community of State DOT engineers, city and county public works directors, and other transportation practitioners.

The Office of Safety's Roadway Safety Data Program (RSDP) team has been working directly with State and local transportation agencies across the country to identify noteworthy practices and success stories that can be broadly applied to improve roadway safety nationwide. Program staff recently released a new set of case studies focused on innovative ways to use GIS to advance highway safety.
Among the agencies identified is the Delaware Valley Regional Planning Commission (DVRPC), which is successfully using GIS to incorporate safety into elements of the transportation-planning process. Integrating GIS-based safety analysis into the planning process promotes a data-driven decision-making process, which in turn leads to better safety decision making. Integrated safety data also helps agencies develop performance-based approaches to planning and programming that help them meet the requirements for accessing Federal safety funds. The principal benefit of a data-driven, GIS-based safety analysis is an improved ability to identify and prioritize high-crash locations and to glean fact-based information that can be integrated into transportation plans alongside other elements that drive the planning process, such as congestion, air quality, and sustainable design, among others.
Further west, Iowa, which has successfully used GIS to implement a snowplow project that provides real-time weather and road condition information. To gather this information, the Iowa DOT used its existing communications infrastructure and the snowplows deployed on a regular basis in the winter. The project has made it possible for Iowa DOT to:
In addition, Colorado is using GIS to spatially integrate roadway data with crash data, develop safety performance functions (SPFs), visualize data, and implement the Level of Service of Safety (LOSS) method to assess a roadway's safety performance. The principal output of LOSS is a collection of calibrated SPFs for highway types and intersection configurations. By analyzing these, analysts can develop sophisticated predictive and diagnostic tools, which in turn informs policies or safety countermeasures to maximize crash reductions across the State–and within budget constraints.
Another recent case study examines the effective use of usRAP and UPlan by the DOTs in Kentucky and Utah, respectively. The United States Road Assessment Program (usRAP) is a tool transportation agencies can use to rate their roadways for safety and identify strategies for systematic improvement. UPlan is an interactive mapping platform that helps the Utah DOT visualize its data, track its assets, and strengthen its transportation planning through better analysis and collaborative information. Both programs include data collection and analysis methods that facilitate highway safety improvements. In addition, UPlan deploys usRAP protocols for risk mapping and has customized these protocols to provide maps and data for a series of safety performance measures.
For more in-depth information on how GIS can be used to improve safety in your state, check out the case studies at http://safety.fhwa.dot.gov/rsdp/safety_casestudies.aspx.

Center line and shoulder rumble strips are proven safety countermeasures for reducing roadway departure crashes, including head-on crashes and run-off-road crashes, but not all roadways are good candidates for rumble strips. So how do practitioners know where rumble strips can be most advantageous for reducing roadway departures?
The Office of Safety and Office of Safety R&D developed the new Decision Support Guide for the Installation of Shoulder and Center Line Rumble Strips on Non-Freeways to provide a framework that will inform center line and shoulder rumble strip installation decisions. It describes methods for identifying appropriate locations for installation, assessing the potential crash reductions and benefit-cost ratio, and developing performance metrics for safety. In addition, the guide addresses special considerations for rumble strip installations – such as bicyclist activity, potential noise impacts, pavement quality, and maintenance activities. It also identifies variability in current practices.
The decision-support framework covers policy development for systematic rumble strip installation and provides a flowchart for decision-making for sites that can benefit from installation but do not meet criteria for systematic installation. The framework can also be applied to sites that are identified based on crash history, such as for Highway Safety Improvement Program selection. Within this framework, this guide describes who may be involved in the decision-making process and at what points those individuals' inputs should be sought. It also provides an overview of safety performance measures that can be presented to policy makers and stakeholders. Performance metrics described in this guide can be used to inform stakeholders of rumble strip benefits.

As America's driving population ages, resources addressing the needs of those drivers become increasingly important. Just over a year ago, the Roadway Safety Foundation, with support from the Federal Highway Administration and National Highway Traffic Safety Administration, launched the Clearinghouse for Older Road User Safety (ChORUS) at www.roadsafeseniors.org.
ChORUS serves as a centralized, user-friendly, and dynamic source of information pertaining to highway safety for aging drivers, passengers, pedestrians, and cyclists. Built as a comprehensive resource, ChORUS offers a wealth of information useful to researchers, engineers, industry, the media, and the general public. Safety practitioners will find that ChORUS offers quick, easy access to design guidelines for the aging population, technical documents, case studies and success stories, and information about innovative financing solutions. From retroreflective signage that helps older drivers navigate at night, to high-visibility crosswalks that allow drivers to more easily see pedestrians, to left-turn lanes that improve sight distance at intersections and prevent deadly right-angle crashes, infrastructure solutions are integral to enhancing safety for the aging road user.

Roadway departures account for about half of all fatal crashes that occur each year in the United States, according to the Fatality Analysis Reporting System (FARS). The FHWA Roadway Departure (RwD) Strategic Plan defines a roadway departure crash as one that occurs after a vehicle crosses an edge line or a center line, or otherwise departs the traveled way. FARS data also show that 40 percent of these crashes involved a collision with a fixed object. Roadside trees and utility poles comprise 63 percent of the fixed objects struck, making them the most harmful event in 14 percent of all fatal crashes.
By working to reduce run-off-road crashes that involve collisions with trees and utility poles, States can reduce fatal crashes significantly. To help agencies address this safety concern, the Office of Safety recently released a guide entitled Noteworthy Practices: Roadside Tree and Utility Pole Management. The practices described within this report offer a snapshot of many alternative approaches in use by State agencies. Leveraging a comprehensive 2014 roadway departure survey, FHWA was able to examine responding States' levels of engagement with all aspects of roadway departure, including crashes into trees, utility poles, and other fixed objects. The resulting report provides agencies with examples of a dozen successful–and immediately deployable–tree and pole practices in use today.
These practices, which range from complex, multi-million dollar contract solutions to in-house efforts that can be accomplished with minimal resources, have been drawn from every region of the United States as well as from previous research. In this report, readers will learn how Washington is using network analysis to target problem locations, how New Jersey is using utility poles that absorb crash energy to mitigate the severity of crashes, and how Nebraska has adopted the practice of re-establishing clear zones during resurfacing, restoration, and rehabilitation (3R) activities. Other case studies highlight successful practices applied to address roadway departures involving tree and utility pole collisions in culturally sensitive or environmentally constrained areas.

Incorporating a transit access focus into the RSA process is a unique undertaking due to the complexity of facility ownership. In many instances, transit agencies are responsible for providing local service to the community and operate on roadways maintained by the State or local road agency or a private authority. However, lighting and intersection traffic signals may be maintained by different sections within a locality's transportation or public works agency. The transit agency may work with the locality to solicit input, but the transit agency is ultimately responsible for planning routes, operating service, and selecting and maintaining transit stop locations. The transit agency may need to work with a variety of agencies or entities to install the transit stops and any associated amenities. A Transit Access RSA provides the opportunity for these agencies to improve their working relationships as they identify and address safety concerns related to transit use and access.
To help Federal, State, Tribal, and local agencies understand and address the conditions and road safety issues that affect transit users, the FHWA recently published four case studies focused on improving access to transit using Road Safety Audits (RSA). The RSA locations included urban and suburban areas with transit facilities and included a multidisciplinary team of planners, engineers, transit managers and operators, and law enforcement. This multidisciplinary perspective was critical to defining approaches to improving transit rider safety using the 4-E approach to safety.
In response to the issues identified during each of the RSAs, a variety of opportunities were identified, including improving ADA compliance, evaluating the need for pedestrian crossing measures, implementing corridor access management techniques, and increased separation of modes. In one location, a Road Diet was suggested to allow for on-street parking, a bike lane, bus-pullout bays, and a combination of curb bulbouts and a pedestrian refuge island at a busy intersection. Any or all of these configurations would serve to improve pedestrian access and safety.
The Improving Access to Transit Using Road Safety Audits: Four Case Studies case studies document is available today!

Speeding is a complicated problem that involves the interaction of many factors including public attitudes, road user behavior, vehicle performance, roadway design and characteristics, posted speed limits, enforcement strategies and judicial decisions. To help tackle this complex and cross-cutting safety issue, the Office of Safety has developed a set of case studies and fact sheets designed to illustrate how to set appropriate speeds and to highlight some effective speed management countermeasures.
Speed Limit Basics [PDF, 1.25 MB] provides introductory information about various types of speed limits and speed concepts and the available technical tools and informational guide for setting different type of speed limits.
Speed Management Countermeasures: More than Just Speed Humps [PDF, 1.37 MB] talks about the variety of speeding countermeasures that are available and which factors should be considered when selecting the most appropriate one.
Speed Management Case Study: Georgia Department of Transportation Setting Speed Limits with Help from USLIMITS2 [PDF, 1.01 MB] provides an overview of how the Georgia DOT used an engineering speed study supplemented by the USLIMITS2 tool to evaluate existing speed limits in Greenville, Georgia.
Speed Management Case Study: Reducing Excessive Speeding in Rural Communities in Iowa [PDF, 1.15 MB] explains how several communities in Iowa employed a variety of traffic calming techniques to inform motorists of incrementally reduced speed limits on the approaches to town centers, encouraging them to slow down and comply with the slower, safer speed limits.

High-quality data and reliable analytical methods are the foundation of data-driven decision making. The new Reliability of Roadway Safety Management Methods series demonstrates the value of more reliable methods and the limitations of traditional methods in roadway safety management. The series includes a guide that demonstrates opportunities to employ more reliable methods to support systemic safety analysis and decisions.
The Systemic Safety Programs guide identifies and describes the systemic approach as a process that is complementary to the crash-based approach. In the crash-based approach, agencies select and treat sites based on the types of crashes that occur at a location. In the systemic approach, agencies select and treat sites based on site-specific geometric and operational attributes known to increase crash risk. Together, these two approaches support a comprehensive approach to safety management.
The guide has several objectives:
The target audience for the Systemic Safety Programs guide includes data analysts, project managers, and program managers involved in projects that impact highway safety. The guide provides information to the user toward implementation of more reliable methods for systemic safety programs. This guide will help users to:
The guide begins by introducing the roadway safety management process and the purpose of safety programs. It describes the similarities, differences, strengths and limitations of the crash-based and systemic methodologies and includes a discussion of how they support a comprehensive approach to safety management.
Systemic improvements are generally low-cost and widely implemented at sites characterized by specific geometric and operational attributes (i.e., those factors known to increase crash risk). This provides an effective way to address safety concerns at a large number of sites, particularly for sites that have few, if any, crashes, but which cumulatively account for a large percentage of crashes in a jurisdiction. For example, there may be few high-crash locations on local or rural roads, but these roads may collectively represent a relatively large safety concern statewide.
Similar to the crash-based approach, a primary challenge related to systemic improvements is justifying the project cost. Using the crash-based approach, an agency can often justify project costs based on the expected crash reductions at the proposed site. This can be a challenge for systemic projects, particularly when the improvements target sites with no recent crash history. Instead of focusing on site-specific benefits, there is a need to focus on system-level benefits, which can be substantial.
The guide demonstrates the value of implementing projects through both crash-based and systemic approaches using empirical examples that provide estimates of average project costs and benefits based on sample systemic projects. Using an optimization equation, the guide demonstrates how an agency can use average project cost and benefit information to allocate funding to different project types, including crash-based and systemic projects.
The following example presents an optimization exercise, assuming hypothetical safety projects and a budget of $10,000,000. The question is how to allocate a safety program budget between relatively high-cost, high-impact projects and low-cost, low-impact projects. In this example, the break even threshold is 2.0 crashes per site per year. For sites with more than 2.0 crashes per year, an agency can achieve relatively attractive benefits through higher-cost and higher-impact projects. For sites with less than 2.0 crashes per year, an agency can achieve relatively attractive benefits through lower-cost and lower-impact projects.
The final sections of the guide summarize the data requirements to employ, and available tools and resources to support, a comprehensive approach to roadway safety management. The guide also explores future research needs to enhance the state of the knowledge on the systemic approach as a conclusion to the guide.

The FHWA Office of Safety recently published two new informational guides to assist with integrating data-driven safety analysis into agencies' business practices. Funding and input for these documents was provided by the Highway Safety Manual Implementation Pooled Fund Study. The first is State Policies and Procedures on the Use of the Highway Safety Manual (HSM), a report designed to assist States in developing policies and procedures on the use of the HSM. Transportation functions addressed in the guide include transportation planning and programming, engineering and design, operations and maintenance, and roadway safety management. The report provides noteworthy examples of existing language in States' policy documents and procedures manuals as well as sample policy and procedures language that can be adapted to a State's individual needs. The HSM provides methods for estimating safety performance that help practitioners, managers, and executives effectively implement strategies to reduce the number and severity of traffic crashes.
The second document is Scale and Scope of Safety Assessment Methods in the Project Development Process, an informational guide that assists State and local agencies in identifying and applying suitable methods for quantitatively assessing the safety performance impacts of project development decisions, such as comparing various design alternatives. The guide suggests assessment methods that may be suitable for answering safety performance-related questions that typically arise during each phase of the development process and for projects of various types. It also provides examples that illustrate the thought process for selecting a safety assessment method. This information on safety performance can then be considered in concert with other project criteria to make more informed highway investment decisions.
For additional information and resources to help implement the HSM into your project development process, visit the Roadway Safety Data Program web page. Also, don't forget that FHWA's Every Day Counts Data-Driven Safety Analysis Initiative offers valuable training and technical assistance opportunities to State and local agencies on how to implement the HSM.

Under the Fixing American's Surface Transportation (FAST) Act and associated FHWA rulemaking, States are required to have in place a safety data system that can be used to perform analyses supporting the strategic and performance-based goals in the SHSP and HSIP on all public roads. Further, States are required to incorporate specific, quantifiable, and measurable anticipated improvements for collection of Model Inventory of Roadway Elements (MIRE) Fundamental Data Elements (FDE) into their State Traffic Records Strategic Plan update by July 1, 2017. [23 CFR 924.11(b)].
State, Tribal, and local agencies are now challenged to develop a fully linked system that includes essential data elements, provides geolocation data, includes the FDE subset of the MIRE, and has analysis and evaluation capabilities.
The FHWA Office of Safety intends to provide agencies with technical assistance to help meet these requirements. FHWA is currently seeking State, Tribal, and local agencies interested in submitting project ideas for technical assistance implementing safety data integration to support safety decision making. Ideal projects will illustrate one of the following:
Selected State, Tribal, and local agencies will have the chance to participate in demonstration projects to energize agencies with similar interests and challenges. FHWA will select up to seven projects with the intention of assisting agencies in implementing the first five of steps of the nine-step safety data integration process shown. At the conclusion of the projects, agencies will receive a clearly defined plan for implementing the remaining four steps.
If your State, Tribal, or local agency is interested in learning more about the opportunity–or would like to submit a project for consideration–please contact your FHWA Division Office Safety Engineer.

On September 30, 2016, the Federal Highway Administration (FHWA) released version 12.0.0 of the Interactive Highway Safety Design Model (IHSDM), a suite of software analysis tools for evaluating the safety and operational effects of geometric design decisions. The NEW 2016 Release expands the IHSDM Crash Prediction Module (CPM) by implementing draft Highway Safety Manual (HSM) crash predictive methods for six or more lane and one-way urban/suburban arterials developed under National Cooperative Highway Research Program (NCHRP) project 17-58.
IHSDM supports the Data-Driven Safety Analysis initiative as part of FHWA's Every Day Counts 3 (EDC3) efforts. The Crash Prediction Module (CPM), for example, is a powerful tool that implements AASHTO's HSM Part C Predictive Methods for rural two-lane highways, rural multilane highways, urban/suburban arterials, and freeways/inter-changes. Typical applications of the CPM include evaluating the safety impact of highway improvements, comparing the relative safety performance of design alternatives, and assessing the safety cost effectiveness of design decisions.
IHSDM includes six evaluation modules, which provide quantitative information on the expected safety and operational performance of a highway design: crash prediction, policy review, design consistency, traffic analysis, intersection review and driver/vehicle.

For the transportation community, evolving technologies mean safer and more efficient travel with expanded options. For people with disabilities, they mean opportunity through access to improved mobility like never before.
The U.S. DOT Accessible Transportation Technologies Research Initiative (ATTRI) is committed to conducting research and developing innovative applications to realize the full potential of these evolving technologies. The program aims to improve the mobility of travelers with disabilities through research, development, and implementation of transformative technologies, applications, or systems for people of all abilities to effectively plan their personal and independent travel.
At the U.S. DOT, safety is always a priority, so ensuring the safety of our intersections is one of ATTRI's key focus areas. In particular, ATTRI is researching applications that provide for Safe Intersection Crossings.
Safe navigation of crosswalks can be a significant challenge for people who need more time to traverse an intersection. For example, if there is no pedestrian refuge area mid-intersection, then signal light duration becomes very important to the individuals on the intersection crossing.
Within this application area, providing safe intersection crossing assistance for all travelers as they interact with existing traffic, signals, vehicles, and assistive devices is critical.
It is imperative that technological solutions–including product design–focus on assistive tools for people with visual impairments, cognitive challenges, and mobility issues. Assistive tools may be in the form of personal nomadic devices, wearable technologies, and kiosks on streets corners to allow for ubiquitous access to connected services.
Applications in this area should, for example, provide guidance, notifications, and alerts in various communication formats to assist pedestrians as well as all transportation users. This will allow users to navigate safely through intersections using real-time information when needed and at the right moment to promote decision making and actions.
These applications could include the following components:
The applications should provide contextual information including geographic information and crowdsource-based information on curb cuts, bus stop locations, side walk grade and slope, and any disruption of the built environment (e.g., damaged infrastructure, dead ends, potholes, etc.) to aid all travelers.
Additional examples could include futuristic and innovative approaches to solving this issue with automated intersection crossing assistance, technical design solutions, or integrated beacons or electronic tags to interact with the built environment.
Using these advanced technologies for safety and mobility at intersection crossings, along with improvements in other priority topics in the development of ATTRI applications, transportation mobility will be enhanced for all road users.
ATTRI is a joint U.S. DOT initiative, co-led by the FHWA and FTA, with support from the Intelligent Transportation Systems (ITS) Joint Program Office (JPO) and the following Federal partners:
ATTRI also relies on collaboration with research institutions, international partnerships, and private industry.
The success of ATTRI relies on these partnerships and collaborations and the collective efforts of several stakeholders. Thus, the program is exploring further cooperation with new and existing partners to test and develop technology applications and prototypes.

The Kentucky State Police (KSP) Commercial Vehicle Enforcement Division is reaching out to students across the Commonwealth with a safe driving campaign called "Teens and Trucks." The program was developed by the Commercial Vehicle Safety Alliance (CVSA) to educate young drivers how to safely drive around large trucks and buses and to reduce crashes involving trucks.
KSP Officer Steve Douglas was in Corbin, Kentucky, recently teaching the class to high school students.
"The Teens and Trucks program is a great outreach tool for student drivers," said Douglas. "Often times, driving courses focus on basic techniques, which is important, but many of these teens never receive instruction about maneuvering around large trucks."
Douglas says even though the course is targeted at teens the concept of the campaign is important for drivers of all ages.
"All drivers need to commit to sharing the road with other drivers–especially large trucks," added Douglas. "Some motorists are under the false impression that because a truck driver sits up high they can see more of the road. When in fact, compared with passenger vehicles, trucks have more blind spots."
Blind spots, also called "No-Zones," are areas around large trucks where the truck driver cannot see a passenger vehicle. (see diagram below). These No-Zone areas are where passenger cars disappear from the view of the truck or bus driver and are where a majority of crashes occur.
"As a driver, if you can't see the mirrors on the commercial trucks you are passing or maneuvering around, you can be sure that the truck driver doesn't see you either," noted Douglas.
He also emphasized to the students the importance of leaving plenty of space when passing large trucks or buses.
"Truck drivers work hard to get up to normal highway speeds, sometimes shifting through as many as 15 gears," added Douglas. "For this reason, and because trucks take longer to stop due their size, I encourage the students to provide ample room when passing and not to cut off the truck."
KSP Major Shawn Hines serves as Director for the Commercial Vehicle Enforcement Division and approved the program for implementation by agency personnel.
"Through education and working together, we can continue to reduce truck-involved crashes on Kentucky roadways," said Hines. "Many of our officers who are teaching this program are parents themselves. They know how important it is for these
young drivers to learn about sharing the road with large vehicles."
KSP reports that in 2015, a total of 9,932 large trucks were involved in collisions, with 108 of those resulting in a fatality. School and commercial buses accounted for an additional 1,566 crashes during the same time period.
Hines says that the teen demographic is important when reducing the number of crashes.
"While teenage drivers only account for 6 percent of licensed Kentucky Drivers, they were involved in 15 percent of all crashes on our roadways last year," notes Hines. "We need to be more proactive in educating our teens about safe driving habits, and this program is a great resource for them. If we can create good habits early, maybe they will stick with these teens into their adult lives as drivers."
