A Review of Pedestrian Safety Research in the United States and Abroad PUBLICATION NO. FHWA-RD-03-042 JANUARY 2004 Research, Development, and Technology Turner-Fairbank Highway Research Center 6300 Georgetown Pike McLean, VA 22101-2296 FOREWORD The overall goal of the Federal Highway Administration’s (FHWA) Pedestrian and Bicycle Safety Research Program is to increase pedestrian and bicycle safety and mobility. From better crosswalks, sidewalks, and pedestrian technologies to expanded public educational and safety programs, the FHWA’s Pedestrian and Bicycle Safety Research Program aims to pave the way for a more walkable future. The following document summarizes research on pedestrian safety in the United States with a focus on crash characteristics and the safety effects of various roadway features and traffic-control devices; it also considers pedestrian educational and enforcement programs. This pedestrian safety synthesis was part of a large FHWA study (“Evaluation of Pedestrian Facilities”) that has generated several other documents on the safety of pedestrian crossings and the effects of innovative engineering treatments on pedestrian safety. These other reports on pedestrian safety likely will interest readers. The results of this research will be useful to transportation researchers, engineers, planners, and safety professionals involved in improving pedestrian safety and mobility. Michael F.

Supplementary Notes This report is part of a larger study for FHWA entitled, “Evaluation of Pedestrian Facilities.” FHWA Contracting Officer’s Technical Representatives (COTRs): Carol Tan Esse and Ann Do, HRDS. 16. Abstract The purpose of this report is to provide an overview of research studies on pedestrian safety in the United States; some foreign research also is included. Readers will find details of pedestrian crash characteristics, measures of pedestrian exposure and hazard, and specific roadway features and their effects on pedestrian safety. Such features include crosswalks and alternative crossing treatments, signalization, signing, pedestrian refuge islands, provisions for pedestrians with disabilities, bus stop location, school crossing measures, reflectorization and conspicuity, grade- separated crossings, traffic-calming measures, and sidewalks and paths. Pedestrian educational and enforcement programs also are discussed. This report is an update resulting from two earlier reports. The most recent was Synthesis of Safety Research: Pedestrians, by C.V. Zegeer (FHWA-SA-91-034, Aug. 1991). The earlier work was Chapter 16, “Pedestrian Ways” by R.C. Pfefer, A. Sorton, J. Fegan, and M.J. Rosenbaum, which was published by the Federal Highway Administration (FHWA) in Synthesis of Safety Research Related to Traffic Control and Roadway Elements (from Volume 2, Dec. 1982). This updated report includes results from numerous studies, foreign and domestic. A review of pedestrian safety research from Australia, Canada, the Netherlands, Sweden, and the United Kingdom is given at: www.walkinginfo.org/rd/international.htm. 17. Key Words: 18. Distribution Statement Pedestrians, safety research, crashes, No restrictions.
