Abstract:This document provides a comprehensive, state-of-the-art review of the operation and control strategies of light rail transit systems. It is intended to serve as a basis for further research in the goals of developing an analytical tool for evaluating the operations of light rail at-grade within an urban signal system. The report identifies the various at-grade crossing types that can exist for a light rail transit system, the operating characteristics of light rail vehicles, and the use of control devices at at-grade crossings. The intent of the report is also to summarize both the priority strategies used by transit agencies and the methods of evaluation used to assess the impacts of light rail transit systems. Simulation has been proposed as a method of analysis; therefore, a summary describing the operation of three applicable computer simulation packages is provided. An appendix of this document provides the minutes of both the technical and steering committee meetings for the project. The minutes are an integral part of the project and have had a significant impact on the study focus, especially in avoiding the duplication of research effort.
