The national agenda for intersection safety was developed as a result of the information, data and discussions that occurred at the National Intersection Safety Workshop held in Milwaukee, WI on November 14-16, 2001. Readers are encouraged to provide comments on the Agenda to Office of Safety, Federal Highway Administration, 400 Seventh Street, SW Washington, DC 20590. The national agenda for intersection safety should be viewed as a "living document," and as such, will be modified periodically based on comments received and actions implemented by transportation and safety agencies.
More
than 2.8 million intersection-related crashes occurred, representing 44 percent
of all reported crashes, in the Year 2000. Approximately 8,500 fatalities (23
percent of the total fatalities) and almost 1 million injury crashes (more than
48 percent of all injury crashes) occurred at or within an intersection environment.
Given this high number of fatalities and injuries at intersections, many transportation
and safety agencies and organizations are developing plans and programs to address
the intersection safety problem.
Intersection safety is one of the emphasis areas in the American Association of State Highway and Transportation Officials (AASHTO) Strategic Highway Safety Plan. The AASHTO Strategic Plan is a comprehensive plan that brings together engineering, enforcement, education and emergency response management. Intersection safety is also included in the Institute of Transportation Engineers' Safety Action Plan. Intersection safety is also included in the Institute of Transportation Engineers' Safety Action Plan. Intersection safety is recognized as one of four priority areas in the Federal Highway Administration's Performance Plan. The FHWA, AASHTO and ITE have several initiatives to improve safety at our nation's intersections.
Traditional and non-traditional organizations must work together to make a substantive difference in the reduction of intersection-related crashes. To focus the transportation and safety community's attention to intersection-safety, AASHTO, ITE, FHWA, State Farm Insurance Company and a host of other organizations, sponsored a National Intersection Safety Workshop. More than 180 transportation and safety professionals convened in Milwaukee, WIS on November 14-16, 2001 for the workshop. The goals were to convene an expert group from the education, enforcement and engineering groups to identify and describe the intersection safety problem, to share and discuss the best practices for improving intersection safety, and most important, to develop a national agenda on intersection safety that provides a vision for the improvement of intersection safety.
The workshop contained presentations focusing on law enforcement, engineering and education topics related to intersection safety, and a series of breakout sessions and conversation circles designed to elicit input from all participants. Each breakout group included 20 to 30 people who focused their discussions on urban, suburban, or rural aspects of intersection safety. Three breakout sessions each had a specific focus.
The first session focused on problem/opportunity identification. The objective was to identify the major issues, challenges and barriers to reduce intersection crashes.
The second session had the objective of developing solutions. The group considered the following: (1) what resources/solutions do we already have in place to assist in intersection crash reduction efforts? what do we have already that is working? (2) what resources/solutions are not in place to assist in crash reduction efforts? and (3) other creative resources/solutions that have not been tried. Within the third session, the objective was to develop the national agenda based on the solutions developed for each group. The agenda included strategies and a discussion of how they might be implemented.
The National Agenda includes 11 categories of solutions and possible strategies. A summary of each strategy is provided below:
1. Programmatic and Legislative Options
Key strategies for programs and legislation recommended by workshop participants include:
This
issue addresses the need to inform political leaders to increase understanding
of the importance of promoting and investing in safety programs. Participants
indicated that transportation and safety professionals should redefine intersection
safety as a quality of life issue. One way to do this would be to demonstrate
benefits, including lives saved. Communications is necessary to get the message
to political leaders and the public that intersection safety is a national public
health issue.
This issue addresses the lack of a systems approach. Good information must get to the local level where intersection safety can be addressed. One strategy includes developing and effectively using partnerships. Improving intersection safety will require the development of strong and permanent partnerships between law enforcement, education and engineering organizations. Participants commented that the "institutional table" needs to be widened to include existing and new advocates, professionals and business groups to support traffic safety initiatives, senior citizens, the disabled and insurance companies.
Communication and a team approach are keys to achieving successes. Partnerships are one way of ensuring communication.
Major issues that were addressed included: (1) lack of reliable data on the effectiveness of various safety countermeasures; (2) lack of focused research on the intersection problem; and (3) the need for a better understanding of human factors as related to the drivers' decision-making process within an intersection environment. Major strategies recommended include the conduct of research on (1) driver information countermeasures, (2) costs and benefits of intersection safety countermeasures, (3) advanced technologies and intersection collision avoidance systems and (4) human factors research.
5. Traffic- and Crash-Record Systems
Participants cited a lack of accurate crash data, specifically, inadequate coding, lack of standardized formats and lack of information on the environment (e.g., signals) at the time of the crash. Participants indicated a dialogue is essential between users and collectors of crash data. The development and use of a standardized crash reporting system was designated as a top priority, including the use of GIS/GPS, logic checks and other quality control measures, and user-friendly applications. The development of a "data warehouse" to provide for common linkages among databases was a second key strategy that was discussed. Another significant issue is the fact that the number of reported crashes to governmental entities is going down. The thresholds for reporting crashes to police are being raised and consequently, traffic engineering and law enforcement agencies may not be getting the entire picture on crash history and patterns at an intersection.
Participants cited lack of understanding of the need for regular signal retiming programs. Proper signal timing is not universally achieved or maintained in numerous jurisdictions because of manpower and budget constraints. Participants cite a need to inform communities, political leaders, and safety and transportation professionals on the safety and operational benefits of signal retiming. In addition, they cited a need to train new and current traffic engineers on how to time a traffic signal.
The Federal Highway Administration is providing training for road safety audits and road safety audit reviews to state departments of transportation throughout the United States. The participants indicated that a program for intersection safety audits/reviews should be developed. More specifically, participants indicated that a national practice is needed and that a separate process should be developed both for urban and rural intersections. The national practice should develop criteria for when an intersection audit should take place using such factors as vehicular and pedestrian volumes, school zones, crashes and complaints. Participants indicated that an understanding of the requirements for pedestrians, cyclists and persons with disabilities should be included in the intersection audit.
Issues include the need to clarify the benefits and dispel the myths associated with automated enforcement and the need to correctly calculate appropriate yellow clearance times at traffic signals. Participants cited the need to develop a best practices manual that would show successful strategies, avoid pitfalls and build support. Participants supported increased enforcement, including the use of cameras as a solution where engineering and education efforts have fallen short.
Participants indicated that substantial information has been produced. However, an inventory is needed to catalogue existing intersection safety analysis tools. It was suggested that a "combined" design and operations handbook for intersections be developed that integrates the requirements of vehicles, pedestrians and cyclists, and the disabled. Part of the need once this information is catalogued is to disseminate it to state and local agencies and communities. Participants indicated that Local Technical Assistance Program (LTAP) centers and the organizations that have participated in the development of the National Agenda for Intersection Safety should be used for this purpose. Access control was another major topic that was highlighted. Again, participants cited a need for a synthesis of state and local design standards and model ordinances, as well as a best practices handbook for access control.
10. Outreach, Education and Training
A
number of challenges in transportation and safety agencies are related to training.
Participants indicated that a limited number of trained professionals, especially
at the local level, a lack of safety training for the design of rural intersections
and a lack of human factors training, are major issues that should be addressed
in the national agenda. Strategies identified include: (1) development and implementation
of a training program for intersection safety that would educate professionals
on those cost-effective improvements that hold the most promise for crash reductions;
(2) increased use of safety peer-to-peer exchanges; (3) training on how human
factors issues impact the complex intersection environment and (4) development
of community education venues and materials for drivers and pedestrians. Overall,
the participants citied the need for all types of training venues such as ITE's
online safety courses, web-based, distance learning resources, university training
and continuing education opportunities. NHTSA's Safe Community Program does
not include intersection safety as a principal component; however, participants
believed that this venue would be an excellent organizational mechanism that
is already in place to conduct intersection safety outreach activities.
11. Marketing and Communications
Intersection safety is not accepted nationally as a public health problem. The public is not getting the message. Participants recommended that a number of steps be taken to address this issue, including the allocation of resources to market intersection safety and the use of communications specialists to conduct market research and to advise transportation and safety professionals on how to market the gravity of consequences for violating the law at intersections. In addition, participants recommended that a media campaign be developed to create and sustain public awareness of intersection safety issues.
Several efforts now in place begin to address the intersection safety problem. The coalition of organizations and agencies that helped developed the National Agenda can begin to use these resources to implement measures to assist with the goal of intersection crash reduction.
This document, the National Agenda for Intersection Safety, can be found on: www.ite.org and http://safety.fhwa.dot.gov. Each organization should review the national agenda and develop its safety action plans within the next six to 12 months based on needs and available resources. During the November 2001 Intersection Safety Workshop, many individuals made personal and organizational commitments to make certain outcomes (e.g., processes) and outputs (e.g., results) happen that would have the effect of reducing intersection crashes. Follow up will occur with individuals on their commitments, and progress will be tracked. The workshop is the springboard for the next phase of the transportation and safety community's efforts to achieve the goal of reducing intersection crashes. Sustained partnerships between the law enforcement, engineering and education professionals will be the key to successful communication and, ultimately, achievement of the goal to reduce intersection crashes.
The National Agenda for Intersection Safety is organized in accordance with the major categories of possible strategies that were developed as part of the Milwaukee, WI Intersection Safety Workshop. These categories are:
S-1: Programmatic and Legislative Options
S-2: Political Support
S-3: Safety Management
S-4: Research
S-5: Traffic Crash Record Systems
S-6: Engineering
S-7: Intersection Safety Audits
S-8: Red-Light Running
S-9: Tools and Best Practices
S-10: Outreach, Education and Training
S-11: Marketing and Communications
Prior to the discussion of the major strategies for achieving reductions in
intersection crashes, a summary of the national intersection safety problem
is set forth.
Intersection safety is a national priority for numerous highway safety organizations. Driving near and within intersections is one of the most complex conditions drivers will encounter. In 2000, there were more than 2.8 million intersection-related crashes representing 44 percent of all reported crashes. Approximately 8,500 fatalities (23 percent of the total fatalities) and almost one million injury crashes occurred at or within an intersection environment. The cost to society for intersection-related crashes is approximately $40 billion every year.
Intersections are areas of highways and streets that naturally produce vehicle conflicts among vehicles and pedestrians because of entering and crossing movements. Reducing fatalities and injuries can only be accomplished by careful use of good road design, traffic engineering choices, comprehensive traffic safety laws and regulations, consistent enforcement efforts, sustained education of drivers and pedestrians, and the drivers' and pedestrians' willingness to obey and sustain the traffic safety laws and regulations.
Despite improved intersection designs and more sophisticated applications of
traffic engineering measures, the annual toll of human loss due to motor
vehicle crashes has not substantially changed in more than 25 years.
Two subgroups are involved in intersection/intersection-related crashes at high levels: senior drivers and pedestrians.
Senior drivers do not deal with complex traffic situations as well as younger drivers do, and that is particularly evident in multiple-vehicle crashes at intersections. People 65 years and older have a higher probability of causing a fatal crash at an intersection, and approximately half of these fatal crashes involved drivers that were 80 years and older. Older drivers are more likely to receive traffic citations for failing to yield, turning improperly, and running stop signs and red lights.
Intersections are disproportionately responsible for pedestrian deaths and injuries. Almost 50 percent of combined fatal and non-fatal injuries to pedestrians occur at or near intersections. Pedestrian casualties from vehicle impacts are strongly concentrated in densely populated urban areas where more than two-thirds of pedestrian injuries occur.
| NUMBER TOTAL | PERCENT | |
|---|---|---|
| Total Fatality Crashes | 37,409 | |
| Total Intersection-related fatality crashes | 8,474 | 22.6% |
| Total Injury Crashes | 2,070,000 | |
| Total Intersection-related injury crashes | 995,000 | 48.1% |
| Total Property-Damage-Only (PDO) Crashes | 4,286,000 | |
| Total PDO Intersection-related crashes | 1,804,000 | 42.1% |
| All Crashes | 6,394,000 | |
| Total Intersection-related crashes | 2,807,000 | 43.9% |
| Total Fatalities | 41,821 | |
| Total Intersection-related injured persons | 1,596,128 |
