FOREWORDTransit administrators, engineers, and researchers often face problems for which informationalready exists, either in documented form or as undocumented experience andpractice. This information may be fragmented, scattered, and unevaluated. As a consequence,full knowledge of what has been learned about a problem may not be brought tobear on its solution. Costly research findings may go unused, valuable experience may beoverlooked, and due consideration may not be given to recommended practices for solvingor alleviating the problem.There is information on nearly every subject of concern to the transit industry. Muchof it derives from research or from the work of practitioners faced with problems in theirday-to-day work. To provide a systematic means for assembling and evaluating such usefulinformation and to make it available to the entire transit community, the Transit CooperativeResearch Program Oversight and Project Selection (TOPS) Committee authorizedthe Transportation Research Board to undertake a continuing study. This study,TCRP Project J-7, “Synthesis of Information Related to Transit Problems,” searches outand synthesizes useful knowledge from all available sources and prepares concise,documented reports on specific topics. Reports from this endeavor constitute a TCRP reportseries, Synthesis of Transit Practice.This synthesis series reports on current knowledge and practice, in a compact format,without the detailed directions usually found in handbooks or design manuals. Each reportin the series provides a compendium of the best knowledge available on those measuresfound to be the most successful in resolving specific problems.PREFACEBy Donna VlasakSenior Program OfficerTransportationResearch BoardThe objective of this synthesis is to report on the mitigation methods tested and used bytransit agencies to reduce collisions between light rail vehicles (LRVs) and motor vehicleswhere light rail transit (LRT) runs through or adjacent to highway intersections controlledby conventional traffic signals. A particular focus is placed on collisions occurring betweenLRVs and vehicles making left-hand turns at these intersections. The synthesis offers successstories and specific actions taken to achieve positive results, as well as examples ofunsuccessful actions. The issues addressed include a range of LRT operations and environmentssuch as median-running, side-running, contra-flow, and mixed-use LRT alignments;urban and suburban setting; and a variety of U.S. geographic regions.This report was accomplished through a review of the relevant literature and surveys ofLRT systems that took the form of structured telephone interviews. This was done, asdirected by the expert topic panel, to obtain more detailed and comprehensive informationabout particular items and to allow the consultants to probe deeper for more completeresponses. With the population for the synthesis survey being only 15 LRT systems, theconsultants and expert topic panel members agreed that this would be the best approach.Kelley Klaver Pecheux, Science Applications International Corporation, McLean, Virginia,and Harry Saporta, PB Americas, Inc., Washington, D.C., collected and synthesizedthe information and wrote the paper, under the guidance of a panel of experts in the subjectarea. The members of the Topic Panel are acknowledged on the preceding page. This synthesisis an immediately useful document that records the practices that were acceptablewithin the limitations of the knowledge available at the time of its preparation. As progressin research and practice continues, new knowledge will be added to that now at hand.
