The series comprises technical reports, state-of-the-art documents, newsletters and bulletins, manuals and handbooks, bibliographies, and other special publications. All share a primary objective: to contri- bute-to a better base of knowledge and undarstcmding throughout the transportation community, and, thereby, to an improvement in the basis for decision-making within the community. This title in the series presents an overview of light rail transit, an urban transit alterna- tive which has the potential to help fil the need for flexibility in public transportation. The documen~ is designed to make more accessible the body of knowledge that now constitutes the state-of-the-art of light rail lIdnsit. A 5pecial feature is the inclusion of supplementary material to serve as a source-b~ok for further information. iW ACKNOWLEDGMENTS This report is jointly sponsored by the following organizations: .

Lea Transportation Research, Lea Transit Compendium, '/0/1 No.1, 1974 viii I OVERVIEW OF LIGHT RAIL TRANSIT 1 revived interest in light rail transit IN RECENT YEARS, the growing need to move people in and around urban areas economically and with minimum disruption to the quality of urban life and environment has stimu lated an interest in various transit alternatives. I n I ight of the national interest in energy conservation, the need for transit alternatives has become even more pronounced. In the realm of conventional mass transit, both new and extensions to existing rail rapid transit systems are being planned and constructed. Improvements in bus and com- muter rail services are also being planned and implemented in many urban areas. The interest in transit alternatives has also focused on techniques for making better use of existing transportation reS~iJl'ces such as the designation of exclusive lanes for buses and carpools, and the establishmi!nt of demand responsive transportation services, specialized services for the transportation disadvantaged, and subscription bus service. Evaluation of these transit alternatives, as they relate to specific applications, is necessary if citizens are to receive the best transportation service for their tax dollars. lThis state-of-the-art overview, derived largely from documented research and personal contacts, concentrates on streetcar and light rail transit systems as they exist in the U.S. and Canada.

This latter characteristic is the primary feature which dis- tinguishes light rail transit from the electric streetcar - streetcars typically share right-of- way with óther vehicular traffic on public, o;ten congested roadways- Light rail transit is an intermediate-capacity, intermediate-speed mode capable of operating at passenger volumes, and service levels, between those of hilly-separated rapid transit and those of transit opr.ating on public streets or roadways in mixed traffic. It is characterized by flexibility which prf)vides planners with a variety of options in locating and/or relocatinçç routes, and in selecting and utilizing a number of different operating procedu res. ad van tages Light rail transit has the potential of meeting transportation needs within many urban areas, Recent reports have cited a number of advantages of light rail transit, in contrast to several of the other possible alternatives (references 47. 52, and 54, DeGraw). The attributes most often cited are: . Light rail transit offers flexibility in right-of-way selection. It can be used under- ground in subways. at grade either on exclusive
