8 CHAPTER 1 Introduction Research Problem Statement To facilitate the compilation of safety data, guidelines are needed to enable transit agencies to report comparable safety Many major metropolitan regions in North America are data in a consistent and comprehensive fashion that will currently planning, constructing, or already have LRT systems. support research and help to improve LRT safety. Although these systems have excellent overall safety records, collisions do occur, and public perception often runs counter to the statistics. TCRP has produced several reports dealing Research Objectives with pedestrian and motorist safety along LRT alignments. The The TCRP established three objectives in the Research Proj- reports include TCRP Report 17: Integration of Light Rail Tran- ect Statement.

These research efforts, and others, looked at a number of systems, identified safety measures, and proposed safety The activities of this project were organized in two Phases, enhancements, but they did not include a systematic approach and framed by 12 Tasks defined by the TCRP.
