Combating the Crisis of Rising Roadway Fatalities

I write this at a time when we are all appalled by the fatality numbers for the first half of 2021. Secretary Buttigieg delivered the grim news during the American Association of State Highway and Transportation Officials (AASHTO) annual meeting in San Diego. We saw the largest 6-month increase in fatalities ever recorded in the history of the Fatality Analysis Reporting System (FARS). An estimated 20,160 people died in motor vehicle crashes on our roadways during this time, an astonishing 18.4-percent increase over the same period in 2020.

If this trend continues, 40,000+ people could lose their lives on our roads in 2021. To echo the Secretary's words, this situation is a crisis. This increase in fatalities is unconscionable. Back in 2020, we were shocked when fatalities increased even while vehicle miles traveled precipitously decreased. With this continued uptick in fatalities in 2021, we cannot view 2020 as an anomaly. We are truly in a crisis, and it's a crisis for everyone—particularly the people who lost their lives and the families and friends left behind. The stakes could not be higher as we continue to push forward and seek new ways to eliminate fatalities on our roads.

First and foremost, we have unprecedented opportunities to advance safety through the $1.2 trillion Bipartisan Infrastructure Law. The Bipartisan Infrastructure Law has safety as a foundational mission and will enable crucial investments in safety for our Nation's roads.

In addition, the U.S. Department of Transportation (USDOT) is finalizing a National Roadway Safety Strategy, which will consolidate and streamline the safety-related work being executed by the modal agencies and will set forth a comprehensive set of actions to work with our partners to significantly reduce road deaths and serious injuries.

FHWA has also just released information on nine new Proven Safety Countermeasures (PSCs)—road design elements and strategies that markedly improve road safety (see page 2). The new PSCs include rectangular rapid flashing beacons, crosswalk visibility enhancements, bicycle lanes, lighting, pavement friction management, wider edge lines, variable speed limits, appropriate speed limit setting, and speed safety cameras. The data show that these strategies can have a huge impact on road safety.

Finally, our revamped Focused Approach to Safety (FAS) initiative (see page 3) will also provide key resources to focus States. These States will receive priority access to technical assistance to address the most common types of crashes that result in fatalities (roadway departures, intersection crashes, and pedestrian/bicycle crashes).

While we are dismayed by the increase in fatality numbers in 2021, we are mobilized to address this crisis. We look forward to working with our partners both inside and outside USDOT to reverse these numbers and decrease fatalities on our roadways.

By Philip Bobitz, FHWA Office of Safety

In October 2021, the FHWA Office of Safety introduced nine NEW countermeasures to the Proven Safety Countermeasures initiative (PSCi). These additions enhance the already diverse set of safety strategies for State, local, regional, and Tribal transportation professionals to consider implementing as part of their efforts to improve safety for all road users on the Nation's roadways.

In addition to nine new countermeasures and crosscutting strategies, this most recent iteration of the PSCi adds recent research and considerations to the existing proven safety countermeasure (PSC) materials. New features have been added to the PSC website, including a filter tool and search function that will help practitioners identify applicable countermeasures that meet their needs.

Widespread implementation of PSCs, where appropriate, can serve to accelerate the achievement of local, State, and national safety goals. The updated PSC website is the one-stop shop for resources and information to advance the now 28 countermeasures for your jurisdiction.

Since 2004, FHWA has used FAS, a unique, data-driven, agency-specific approach to safety, to offer priority assistance to select focus States in order to reduce fatalities and serious injuries on the Nation's highways. In October 2021, an adjusted and updated FAS was rolled out based on current data and program evaluation. A refreshed FAS web page includes the explanatory update memo, the list of new focus States, frequently asked questions, and a link to the public webinar recording.

This 2021 update relied on 6 years (2014–2019) of data from FARS, Census Bureau, and FHWA highway statistics. Some of the notable changes implemented with this update include:

These 16 new focus States, shown in the map, represent 51 percent of all traffic-related fatalities that occurred in the United States during the analysis period. Within these 16 focus States, there were also 23 MPOs/regions over-represented for fatalities in the intersections, pedestrians, and bicyclists focus areas.

As with past iterations of FAS, FHWA is providing priority technical assistance and training to the focus States.

Safe System Strategic Plan: A New Resource on Implementing the Safe System Approach Together

By Norah M. Ocel, P.E., FHWA, Office of Safety

The FHWA Office of Safety is pleased to share a new resource with the transportation community: the Safe System Strategic Plan. This publication is the product of collaboration and cooperation among many organizations that are part of the Road to Zero Coalition. These organizations worked together and shared input on how to move the Safe System Approach forward in the United States.

Other countries that have embraced the Safe System Approach have seen impressive outcomes. The United States has unique perspectives and it will take many partners working together, including transportation system planners, designers, builders, operators, and users (drivers, bicyclists, and pedestrians) to advance the Safe System Approach. Embracing this approach will take:

When we have the political will, the adequate processes, and the public demand for facilities that accommodate every single road user regardless of their mode of transportation, we'll get closer to zero.

The Safe System Strategic Plan is a roadmap for transportation professionals in the United States to implement the Safe System Approach with immediate, near-, and long-term time frames. FHWA is committed to its partnership role in implementing the Safe System Approach, and hopes transportation stakeholders will work together and have meaningful conversations about what it will take to implement the items identified in the plan. We hope everyone in the transportation community will be part of the conversation and implement, to the best of their abilities, many of the action items to further advance the Safe System Approach. The Safe System Approach should be the way our transportation system is planned, designed, built, and operated.

And remember, let's work together because one life lost on our roads is one too many!

High-Friction Surface Treatments: Creating Friction for Crash Reduction in Pennsylvania

By Joseph Cheung, P.E., FHWA, Office of Safety

In Pennsylvania more than half of fatal and serious injury crashes involve a lane departure. Intersection crashes account for 21 percent of annual fatalities and 30 percent of serious injuries, with a significant fraction of these crashes attributed to slippery and wet road conditions. To reduce wet pavement crashes at curves and intersections throughout the Commonwealth, the Pennsylvania Department of Transportation (PennDOT) has been installing high-friction surface treatments (HFSTs) at strategic locations.

HFSTs are a safety countermeasure with exceptional skid-resistant properties intended to restore and maintain pavement friction in wet and dry conditions to reduce crashes. These properties are the result of the application of durable aggregates bonded to the existing pavement by a layer of polymer resin. HFSTs are effective in reducing crashes on horizontal curves and ramps, intersections, and pedestrian crossings, especially those with limited sight distance. HFSTs are also suitable for high traffic volume, conditions where the road will need to reopen to traffic quickly, and roads within an environmentally sensitive area. An FHWA advanced statistical study using empirical Bayes methodology shows a crash reduction of 57 percent for total crashes and a crash reduction of 83 percent for crashes on wet curves.

PennDOT piloted its first HFSTs at a high-crash location along State Route 611 in Northampton County (District 5). The treatment was located at a sharp horizontal curve on a rural, two-lane road with 9-foot travel lanes and no shoulders. In the 10 years prior to installation of HFSTs, 20 wet pavement-related crashes occurred at the site. An analysis of the crash data over the next few years after HFSTs were installed revealed the project experienced zero wet pavement-related crashes. Since then, PennDOT has used the treatment in areas with a history of a high number of rear-end or off-road crashes. PennDOT says studies in other parts of the State have shown HFSTs to be highly effective. According to PennDOT, 47 locations reviewed 3–5 years after the surface was applied experienced a "significant crash reduction." Most notably, one location in Northampton County saw a 100-percent reduction in crashes.1

While PennDOT has installed HFST at approximately 500–600 locations Statewide, District 11, including Allegheny County, has just started installing HFSTs in the past couple of years. Recently, PennDOT and Allegheny County targeted several locations with dangerous curves or intersections with high rear-end collision rates. In September, PennDOT and Allegheny County installed HFSTs at five locations in Penn Hills on Frankstown Road and Allegheny River Boulevard, Westinghouse Avenue in North Versailles, Lincoln Way in White Oak, and Route 88 in Castle Shannon. In parallel, Allegheny County began installing HFSTs on September 27 on Vanadium Road between Route 50 and Main Street in Collier Street and Scott Street. The work was completed with little or no traffic interruption, as most of the work was performed at night, and the road segment reopened to traffic the next morning.

PennDOT considers HFSTs an innovative low-cost option to deal with high crash locations, especially when dealing with friction and wet weather-related crashes. It is much more cost-effective than redesigning the roadway. The rolling terrains with steep grades and horizontal curve sections in District 11 lead PennDOT to believe applying HFSTs to reduce crashes will be widespread in this region as well.

FHWA Hosts Virtual Peer Exchanges on Safe System for Pedestrians and Bicyclists

By Tamara Redmon, FHWA, Office of Safety

On March 19, FHWA hosted a virtual peer exchange on the Safe System Approach for pedestrians and bicyclists, which followed along with the recently developed Primer on Safe System Approach for Pedestrians and Bicyclists. The purpose of this primer is to provide transportation agencies a baseline understanding of the Safe System Approach and how it relates to bicycle and pedestrian safety. The FHWA Office of Safety has been encouraging applications of Safe System to be adopted nationally.

The peer exchange discussion focused on planning-level applications, followed by project-level applications of Safe System. The goal of the meeting was to talk about how to implement the Safe System Approach with an eye to prioritizing safety for pedestrians and bicyclists and to reflect big takeaways, participant concerns, and lessons that could be useful for other agencies doing similar work.

Image shows responses to Are you planning to implementing the Safe System approach? 63%, or 12 participants, said yes, right now. 21%, or 4 participants, said yes, but not yet. 3 participants, or 16%, said Not sure, this gaveme a lot to think about. 0% said not likely. Image shows responses to What would you need to implement the Safe System Approach? 37% or 13 participants, said Buy-in from decision makers. 23%, or 8 participants, said More examples. 17%, or 6 participants, said Buy-in from peers. 14%, or 5 participants, said Coordination among departments/agencies. And 9% or 3 participants said More guidance.

Safe System Approach poll questions. (Source: FHWA)

The peer exchange was attended by participants from departments of transportation (DOTs) in California, Florida, Maryland, Pennsylvania, Oregon, and Washington State. Moderators closed the day with a final discussion about implementation of Safe System moving forward. This started with a few poll questions. The responses are summarized in the illustration above. Participants thought that it would be valuable to have Safe System messaging from all Federal agencies, and a few suggested that mandating the adoption of the Safe System Approach would be a big step forward.

FHWA held a second peer exchange on April 14 on Pedestrian and Bicyclist Safety Action Plan (PBSAP) development. The peer exchange followed a webinar held on the preceding day in which participants from State agencies were also invited to participate in the virtual peer-to-peer event. Representatives from 19 State and local governments attended.

PBSAPs are valuable tools that can help transportation agencies establish a framework and approach for reducing deaths and serious injuries among vulnerable road users. FHWA developed How to Develop a Pedestrian and Bicycle Safety Action Plan many years ago to help guide agencies through the steps required to develop their own action plans for improving safety. During the webinar, authors of the guide reviewed the elements of successful PBSAPs and described how State DOTs can develop their own plans. Panelists from Virginia and Oregon discussed their approaches to crafting and implementing their plans and offered lessons for the audience. You can review the recording here.

During the peer exchange, participants discussed safety action plan development with other State agencies and representatives from FHWA. The session was largely a discussion and was intended to support agencies in the process of developing their own action plans.

Some key takeaways that agencies noted when establishing a vision and goals for their plans include:

Training Updates from the National Highway Institute

By Thomas Elliott, NHI, and Sabrina Sylvester, contractor for NHI

The National Highway Institute (NHI) focuses on providing innovative and relevant training that meets the needs of today's transportation industry. NHI recently released a course for highway safety practitioners and students to learn the concepts and processes of road safety and the reduction of road fatalities.

New Training: Road Safety Fundamentals

In 2017, FHWA published the Road Safety Fundamentals textbook, which introduces the fundamental concepts of road safety. In the textbook, students learn the landscape of road safety issues and human behavior pertaining to the road environment and identify ways to address safety challenges. This Road Safety Fundamentals textbook is widely used as one of the reference materials for the Road Safety Professional Certification. The textbook's objective is to prepare the reader with foundational road safety knowledge.

Road Safety Fundamentals (Textbook) (FHWA-NHI-380124A) is a web-based training that teaches the concepts of road safety in all phases of roadway design, operation, and maintenance. Upon completing this course, participants will learn the history of road safety, multiple disciplinary methods, understanding of human behavior, various types and importance of safety data, problem solving through a safety management process, and the process of implementing road safety efforts. Participants also explore these concepts of road safety through resolving common safety issues, evaluating data to develop various road safety objectives, and strategizing achievable steps to enhance road safety and reduce fatalities.

NHI designed this online training in an innovative learner-centric format where instructors encourage learners to interact with the content in various and meaningful ways. Through an in-video format, participants engage with the content, including infographics and downloadable worksheets, to reinforce key learning points throughout the course. These resources will help the participants refine and further their comprehension of the materials on road safety.

This course is expected to take an average of 12 hours of training time. Participants can work through the course materials and assignments at their own pace. At the end of the training period, participants who pass the exam with a grade of 70 percent or more will earn 1.2 continuing education credits. Participants who successfully complete the course will also grasp the fundamental concepts of road safety and be equipped to help develop a workforce that is better prepared to address road safety challenges.

To learn about the Road Safety Fundamentals training course, along with other safety training courses, visit NHI's website at https://www.nhi.fhwa.dot.gov//.

Safety Stories

By Chimai Ngo, FHWA, Office of Safety, and Kevin Elliott, ARA

Transportation safety boils down to people, including transportation practitioners themselves. Those who design and deploy safety treatments also travel the roads like everyone else. Many times, they are saved by those very treatments.

This is a series of real stories of people, including transportation practitioners, who had personal experiences being saved from harm by the safety strategies and countermeasures we promote every day. Their stories drive home the importance of making safety a top priority in the transportation industry.

Tony Kemnitz, Wisconsin DOT

Tony Kemnitz, a traffic safety engineer with Wisconsin DOT, knew something had to be done after the mother of a young man who had died on a curve in Tony's jurisdiction reached out to Tony. The young man was returning home following a friend's bachelor party. He was, no doubt, tired and drifted across the centerline on a curve, striking an opposing vehicle.

After this young man's death, Tony prepared an improvement plan for the roadway that justified the cost of installing centerline rumble strips on the curve with a nearby project. The man's mother was able to attend the installation.

"Unfortunately, it is an after-the-fact response. But we were able to respond and make the highway safer," Tony said. "We did not save that young man, but we did help reduce the chance for another mother (family) to suffer the loss of a family member." Here is a link to news coverage of this story: https://www.wsaw.com/2020/10/19/mother-of-man-killed-in-crash-gets-dot-to-install-rumble-strips-on-hwy-73/.

For Tony, roadway safety is a personal matter.

"I lost my brother-in-law and his girlfriend in a fatal crash in 1990. This caused me to change my career path and pursue a traffic engineering position with a goal of improving safety and operations on our roads," Tony said. "That is why I do what I do. Best job I have ever had because in doing it you can save lives."

Yanira Rivera, FHWA

Yanira, a safety engineer in the Eastern Federal Lands Division Office, was driving home after a long day. She had worked a full-time job and then attended evening classes while finishing her civil engineering degree. As she embarked on her 40-minute commute home, tired from a long day, she didn't realize how fatigued she felt. When her vehicle began to drift from the travel portion of the road, rumble strips alerted her of the potential danger by causing a vibration and audible sound through the wheels of the vehicle.

"Thank goodness for those rumble strips. Otherwise I probably would have left the road and hit a tree or other fixed object," Yanira said. "That experience stayed with me so much that I decided to study centerline rumble strips for my master's project."

Did you know rumble strips are an effective deterrent to roadway departure crashes? According to the FHWA Rumble Strips and Rumble Stripes Technical Advisories, milled centerline rumble strips can provide a 38–50-percent reduction in head-on and opposite-direction, sideswipe injury crashes on rural, two-lane roads. Milled shoulder and edge rumble strips provide significant reductions in single-vehicle run-off-road injury crashes: 10–24 percent on rural freeways and 26–46 percent on two-lane rural roads.

Visit the FHWA Rumble Strips and Rumble Stripes web page for additional information: https://safety.fhwa.dot.gov/roadway_dept/pavement/rumble_strips/.

Do you have a story to share? Do you know someone in your organization whose life was saved by safety treatments or whose career was inspired by a safety story? If so, please contact Chimai Ngo at chimai.ngo@dot.gov.

Puerto Rico Highway Safety Corridor Program

By Grace Diaz-Estrada and Juan C. Rivera-Ortiz, area engineers, FHWA Puerto Rico and USVI Division

Puerto Rico is called the Island of the Enchantment for its national resources, friendly people, food, and other amazing things that anyone can see on a small 100-by-35-mile island in the Caribbean. At first glance at the Island of Enchantment, one may not notice its highway safety program. Under Section 165 of Title 23 of the United States Code, the Puerto Rico Highway Safety Program must annually obligate at least 25 percent of its Federal funds to projects or programs eligible under HSIP. The 25 percent of the total Federal funds is approximately $30 million a year in highway safety projects. As highway safety engineers, this requirement is music to our ears. But what happens if the highway safety program of the Puerto Rico Highways and Transportation Authority (PRHTA), grantee of the FHWA funds, is not prepared to obligate highway safety improvements projects due to lack of a data-driven approach and a safety culture in engineering processes? These obstacles were overcome by a passionate group of professionals who pioneered the highway safety program in PRHTA and developed the Puerto Rico Highway Safety Corridor Program.

Let's go back in time to the year 2013 and begin the description of our program. In that year, Puerto Rico completed its first SHSP. In developing the plan, the engineers found that crash reports in the police department of transportation had been completed manually and there was a backlog of 4 years of data to be entered into the crash database—meaning a data-driven analysis was not feasible due to lack of data. The first step in developing a Highway Safety Corridor Program was looking for innovative ways of having crash data for analysis. The Traffic Records Coordinating Committee worked on various efforts in this area, and from 2013 to the present, made achievements in the data category.

The 4-year backlog in the crash database was eliminated in 2015 in phases. The first phase entered only fatal and serious injuries crashes in the database. When the personnel of the Office of Collection and Analysis of Crash Data completed this first phase, they began entering the crashes with property damages only in the database. This effort required the collaboration of different agencies to provide staff on rotational assignments for evaluation and database entry of crash reports.

"Knowledge is one of the most powerful tools in the decision-making process."

– High Crash Location Report

At the same time, the police department was updating the crash form with the Model Minimum Uniform Crash Criteria requirements and developing an electronic crash form that allows crash information to be obtained in 24–48 hours. The electronic crash form was completed in 2019 and began implementation in 2020. This was a breakthrough in data analysis.

After data efforts were completed, the next step was to develop a data analysis approach. In 2017, the engineers from the public and private sector collaborated on the development of the High Crash Location Report (HCLR). With the phrase, "Knowledge is one of the most powerful tools in the decision-making process," transportation professionals developed HCLR to guide Puerto Rico to a better understanding of the roadway locations that need more attention from the 4Es of safety (engineering, education, enforcement, and emergency medical services [EMS]) to reduce the number of fatalities and serious injuries caused by traffic crashes. The HCLR defines corridors (3 kilometers or more), spots (500 meters), and intersections with higher crash cost factors and frequency indexes for specific 3-year periods. The list of roads by functional classification, SHSP emphasis areas, and special cases (motorcyclists, festive periods, older population, and transportation management areas) was vital for the initial steps of the Highway Safety Corridor Program. Another objective of the HCLR was to assist the other 3Es (enforcement, education, and EMS) in the development of their safety and security plans.

Process starts with Highway Safety Corridor Program, which leads to Training, which leads to Update of Standards and Specifications, which leads to Selection of Highway Safety Corridors, which leads to Road Safety Audits, which leads to Design Program. This leads to both Preliminary Engineering Report and Plans Development, which both leads to the last step, Evaluation.

Once the data barrier was overcome, the next goal was to promote a safety culture among senior management and engineering departments. Safety should be a top priority and must be evaluated in all projects with the inclusion of PSCs in other States and territories or recommended by FHWA programs (e.g., Every Day Counts).

The Highway Safety Division in PRHTA used the following process to implement the Highway Safety Corridor Program (see flowchart):


A highway safety corridor project requires the evaluation of all road users and how the deficiencies and problems identified in the corridor will be impacted by the engineering measures. It was important to promote education to designers in the public and private sector on the innovative engineering measures that will be included in the highway safety projects. With the collaboration of FHWA Puerto Rico and U.S. Virgin Islands Division and the Puerto Rico Local Technical Assistance Program, the transportation community received the following training:

Update of Standards and Specifications

The trainings helped us understand that our standards and specifications in the PRHTA needed to be updated to incorporate the new safety countermeasures. New specifications and standard drawings were developed for rumble strips, HFSTs, safety edge, and guardrails (in compliance with Manual for Assessing Safety Hardware [MASH] requirements).

Selection of the Highway Safety Corridors

Engineers and planners selected safety corridors that would be included in the program. The maps and tables of the HCLR were used in the selection of the corridors, and it was important to schedule the projects for the next 4 years. A 4-year plan of highway safety corridor projects was included in the Statewide Transportation Improvement Program and in consultation with the MPO.


An efficient highway safety program requires the cooperation and involvement of all road users and stakeholders. The development of RSAs in some of the highway safety corridors was a good exercise to know how representatives from other safety areas (enforcement, education, and EMS) think about and solve highway safety problems from their perspective. The results of the RSAs were included in the planning phase of future safety projects.

Design Program

PRHTA invested State funds in the selection of designers (private sector) to initiate the design of highway safety corridors that had been chosen in the 4-year plan. The design program was divided in two phases, with a total investment of approximately $120 million over the 4 years. Designers will complete the plans of the highway safety projects in a two-step process: preliminary engineering reports (PER) and plans development.


During this step, designers collected information on crash data, geometry, pavement, and RSA recommendations to produce a report with analysis of the crash data, expected reduction in fatal and serious injuries crashes, and identification of safety countermeasures. Designers presented the report to State engineers and FHWA representatives. At the end of the presentation, designers received from PRHTA the notice to proceed for the elaboration of plans with the safety alternatives recommended in the PER and selected during the meeting.

Plans Development

In this step, the designer completed the environmental studies and developed the plans, specifications, and estimations for the projects. To develop a safety culture as part of the programs, all designers should consider the following countermeasures in their projects:

Most of the highway safety corridors are currently under construction, except for several that were completed in 2019 and 2020. PRHTA expects to implement an evaluation program with the development of before-and-after studies with data from 3 years before improvements and 3 years after. This evaluation process with the before-and-after studies will provide us with the tools to improve our current highway safety program, including trainings and new ideas for the design process.

Our Federal-aid program is not the largest in the Nation, but it is not the smallest either in comparison with other territories. With the lack of State funds for the development of preservation and construction programs, the use of Federal funds is essential to continue with improvements to our highway system. The efficient use of resources, labor, and funds is key in the implementation of the Puerto Rico Highway Safety Corridor Program. Our goal is to involve all design firms on the island (more than 20 firms) in the process of designing highway safety corridors to spread the seed of safety and innovation in their minds.

Puerto Rico has been working hard to implement a safety culture in the PRHTA and all engineering processes. Fatalities on the Island went from 308 in 2018 to 289 in 2019 and 242 in 2020. Collaboration among all stakeholders as part of the SHSP efforts and the implementation of the Puerto Rico Highway Safety Corridor Program have contributed to the reduction of fatal crashes on the island. In addition, the Puerto Rico Highway Safety Corridor Program has been effective in encouraging a safety culture in the Puerto Rico transportation community. This program is helping us prioritize highway safety in all project and investment phases. Fatalities on the island have been on a downward trend over the years, and the improvements in the highway system have played an important role.

Making Work Zones Safer with Better Data: Introducing the Work Zone Data Exchange

By Martha Kapitanov, FHWA, Office of Operations

Work zone safety is a national priority. USDOT, FHWA, and transportation agencies are working to reduce fatalities, injuries, and crashes in work zones nationwide. The United States saw 842 work zone fatalities in 2019.

Looking to the future, technology will play a vital role in improving work zone safety. While intelligent transportation system tools such as smart work zone devices are rapidly advancing, the data they collect are much more valuable if everyone can easily access and interpret it. And that's where the Work Zone Data Exchange (WZDx) comes in.

What is WZDx?

WZDx is a cooperative effort led by USDOT and stakeholders to advance a national data specification—a universal language—for all work zone data. WZDx supports the sharing of all data (and there are a lot of it), making it available for third-party users such as mapping companies, vehicle and vehicle equipment manufacturers, and automated vehicles.

Graphic reads What is WZDx? Work zone data gathered using a common specification. Aggregated by infrastructure owners and operators (IOOs). Published in a common format. Picked up by mapping companies. Delivered directly to roadway users. Learn more and become involved in the future of work zone management: https://ops.fhwa.dot.gov/wz/wzdx/index.htm

Community-developed data specifications, such as the General Transit Feed Specification for public transportation, are widely used by transportation agencies nationwide. The WZDx specification is the first open specification for sharing information on work zone impacts.

Partnering across the Nation

100+ organizations—including State and local DOTs, construction firms, mapping companies, and vehicle technology manufacturers—participate in the Work Zone Data Working Group. Working group members are dedicated to developing and implementing the WZDx specification in work zones nationwide. Any person or organization is welcome to join, and several subcommittees address specific aspects of development and implementation.

Earlier this year, USDOT awarded grant funds for projects in 13 States, including Massachusetts and Arizona. Each project is working to get a WZDx data feed up and running, but each has its own unique elements. Minnesota DOT, for example, is working to create a mobile application that work zone operators can use to report real-time work zone information, such as lane shifts, closures, and worker presence.

Looking to the future

"Work zones are particularly problematic for commercial motor vehicles and automated vehicles. Just imagine if automated vehicles could access live data that tell them where workers are in a work zone, when the lanes are going to shift, and even when to slow down and avoid crashes."

– Martha Kapitanov, FHWA

Like all technology, progress is incremental. In the case of WZDx, things are moving along at a rapid pace. Version 4 of the specification is coming soon, and with each version, the data that the WZDx is capable of communicating become more comprehensive and more precise. And precise data are more useful data.

Ultimately, WZDx will save lives and make travel on public roadways safer and more efficient—but to gather data from across the country, broad adoption is critical.

Let's Put Work Zones on the Map

The first step in accelerating adoption is to get the word out. Earlier this year, FHWA launched a partnership and awareness campaign, called Put Work Zones on the Map, to do just that. The purpose of the campaign is to educate and engage potential partners on the capabilities, benefits, and progress of WZDx. Those interested in helping spread the word can visit the campaign's toolkit web page to find fact sheets, social media content, and links to past webinars.

Together we can create smarter and safer roadways by putting work zones on the map and improving the way we navigate work zones daily. For more information on WZDx and Put Work Zones on the Map, visit the WZDx website or email Martha Kapitanov at martha.kapitanov@dot.gov.

Pedestrian and Bicycle Crash Analysis Tool, Version 3, Available!

By Tamara Redmon, FHWA, Office of Safety, and Ana Maria Eigen, FHWA, Office of Safety R&D

FHWA has released version 3 of PBCAT. PBCAT is a crash typing software product intended to assist State and local pedestrian/bicycle coordinators, planners, and engineers with improving walking and bicycling safety. PBCAT helps road safety professionals improve their understanding of non-motorist crashes. Through development and analysis of a database containing details associated with crashes between motor vehicles and pedestrians or bicyclists, transportation professionals can make their systems safe. One of these crash-associated details is crash type, which describes the pre-crash actions of the involved parties.

After developing a database of crash information, PBCAT users can analyze the data, produce reports, and select countermeasures to address the problems identified by the software. The application allows users to categorize their non-motorist crashes and create a data set for analysis. Version 3 of PBCAT has new graphics and logic, considers micromobility, and is now a web-based tool. Version 3 is free through the Highway Safety Information System web page under Products/Safety Analysis Tools. The accompanying User Guide provides detailed information on how to use PBCAT.

New Resources and Incorporation of the Bikeway Selection Guide into State Planning Documents

By Tamara Redmon, FHWA, Office of Safety

FHWA released its Bikeway Selection Guide 2 years ago. This resource helps transportation practitioners consider trade-offs and make decisions to accelerate the delivery of high-quality bicycle networks.

FHWA also recently completed supplemental resources to complement the Bikeway Selection Guide. The first of these, On-Street Motor Vehicle Parking and the Bikeway Selection Process, is intended to inform discussions about on-street parking and bikeway selection. It begins with a discussion of on-street parking and bikeway types, with associated dimensional requirements and trade-off considerations. It then presents strategies involving choices relating to the overlap between general purpose on-street parking and passenger or commercial loading activities, design details, and bikeway selection.

The other resource, entitled Traffic Analysis and Intersection Considerations to Inform Bikeway Selection, is intended to inform trade-off decisions associated with bikeway selection at intersections. It discusses common performance metrics, spatial needs of bikeways at intersections, safety- and equity-focused design principles, and operational traffic analysis trade-offs and assumptions.

FHWA held a webinar on these two new resources on April 7. The recording can be viewed here. FHWA also held a webinar on the Bikeway Selection Guide when the guide was developed in 2019, which can be viewed here.

As part of the project, 23 workshops were held across the United States between summer 2019 and spring 2021: El Paso, Texas; Jonesboro, Arkansas; Springdale, Arkansas; Chesapeake, Virginia; Columbus, Ohio; Harrisburg, Pennsylvania; Raleigh, North Carolina; Mesquite, Texas; Fort Worth, Texas; Fort Lauderdale, Florida; Denver, Colorado; Coco, Florida; Tampa, Florida; Oklahoma City, Oklahoma; St. Louis, Missouri region; North Carolina DOT; Hawaii DOT; PennDOT; Mid-Ohio Regional Planning Committee; Washington County Council of Governments, Oregon; and Metropolitan Washington Council of Governments.

FHWA offered free technical assistance for 2 years to any State or locality that wanted to use the guide. During this process FHWA documented how States and localities are starting to use the guide. These are some known applications of the guide in local or State plans and documents:

FHWA is very encouraged by the amount of interest in the guide. Enthusiasm for bicycle facilities remains strong and there is increasing demand as popularity of this mode of travel increases throughout the country.

We always like to hear about any new uses and applications of the guide and supplemental resources. If your State, city, or locality is using the guide in other ways, please let us know by contacting Tamara Redmon at tamara.redmon@dot.gov.
