Summary
The *National Agenda for Intersection Safety* addresses the critical public health and safety issue of intersection-related crashes, which accounted for 44 percent of all reported crashes, 23 percent of fatalities, and nearly half of all injury crashes in the United States in 2000. The document was developed following the National Intersection Safety Workshop held in Milwaukee, Wisconsin, in November 2001, which convened over 180 transportation and safety professionals. The agenda aims to provide a comprehensive vision and actionable strategies to reduce intersection crashes by coordinating efforts across engineering, enforcement, education, and emergency response sectors. It identifies significant gaps in current practices, including inadequate funding, lack of standardized data, insufficient political support, and the need for better integration of human factors and advanced technologies. The agenda outlines eleven strategic categories for improvement. Programmatic and legislative options focus on securing dedicated safety funding, tying federal funds to performance standards, and creating safety program funds for local governments. Political support strategies emphasize redefining intersection safety as a quality-of-life issue to engage leaders. Safety management calls for multi-disciplinary partnerships and the integration of safety into planning processes. Research priorities include evaluating the effectiveness of countermeasures, studying human factors in driver decision-making, and assessing advanced collision avoidance technologies. The agenda also highlights the need for standardized traffic and crash record systems using GIS/GPS to improve data accuracy and accessibility. Engineering strategies stress the importance of regular signal retiming and training for traffic engineers. Additional strategies involve implementing intersection safety audits, addressing red-light running through enforcement and proper yellow clearance times, developing tools and best practices handbooks, enhancing outreach and training for professionals and the public, and launching marketing campaigns to raise awareness. The document identifies specific vulnerable populations, noting that senior drivers and pedestrians are disproportionately involved in intersection crashes. It also reviews existing initiatives, such as the AASHTO Strategic Highway Safety Plan, an outreach toolkit, and an infrastructure consortium for collision avoidance technologies. The agenda serves as a "living document" intended to guide state and local agencies in developing their own safety action plans within six to twelve months. By fostering sustained partnerships and implementing these coordinated strategies, the agenda seeks to significantly reduce the annual toll of fatalities, injuries, and economic costs associated with intersection crashes, which were estimated at $40 billion in 2000.
Key finding
The National Agenda for Intersection Safety was established to coordinate multi-agency efforts and implement eleven strategic categories aimed at reducing the 2.8 million intersection-related crashes and 8,500 fatalities recorded in the year 2000.
