Summary
This report documents the findings of an international technology scanning study conducted in May 2009 by a team of U.S. transportation professionals. Sponsored by the Federal Highway Administration, the American Association of State Highway and Transportation Officials, and the National Cooperative Highway Research Program, the study aimed to identify effective strategies for improving pedestrian and bicyclist safety and mobility in the United States. The motivation stemmed from pedestrian and bicyclist deaths accounting for 14 percent of U.S. highway fatalities in 2008. The team visited Denmark, Germany, Sweden, Switzerland, and the United Kingdom, selected for their innovative approaches and the potential transferability of their policies. The methodology involved presentations from foreign hosts, informal discussions, and guided field visits where the team experienced facilities firsthand. The study evaluated strategies across five categories: engineering, education, enforcement, encouragement, and evaluation. The team analyzed how these countries established an urban street user hierarchy that prioritizes walking, biking, and public transit over motor vehicles. This hierarchy influences transportation policy, planning, design, and maintenance, such as designing streets to accommodate pedestrians and cyclists first rather than allocating leftover space. Key findings revealed that higher safety and mode splits in Europe result from a deliberate combination of policies, including integrated land-use planning, high costs for private vehicle ownership, and comprehensive infrastructure networks. The concept of "safety in numbers" was identified as a significant factor, where increased visibility of vulnerable users leads to greater motorist awareness. Engineering observations included innovative traffic signal features like passive pedestrian detection and near-side signals, as well as bicyclist-specific designs such as cycle tracks, bike boxes, and leading green phases. The study also highlighted the importance of low-speed street designs (20–30 km/h) and the close integration of biking with public transit, including bike parking at stations and policies permitting bikes on transit vehicles. Education and enforcement strategies included institutionalized traffic safety education for children and routine photo enforcement. The report concludes with recommendations for U.S. implementation, emphasizing the need for a careful, evidence-based approach. The team advises encouraging transportation policies that prioritize nonmotorized modes in the road user hierarchy and evaluating innovative designs for potential U.S. use. They recommend institutionalizing early-age traffic safety education and developing programs to encourage regular walking and biking. The authors caution that while some practices are immediately transferable, others, such as separated bicycle facilities, may require trial implementations and long-term evaluation to account for cultural and behavioral adaptations. The study underscores that significant safety improvements require a comprehensive, integrated approach rather than isolated interventions.
Key finding
European countries achieve higher pedestrian and bicyclist safety and mobility through a comprehensive strategy that prioritizes non-motorized users in policy and design, utilizes low-speed street environments, and leverages increased user volumes to improve motorist awareness.
