Provides a comprehensive, state-of-the-art review of the operation and control strategies of light rail transit systems (LRTS). Intended to serve as a basis for further research in the goal of developing an analytical tool for evaluating the operations of light rail at-grade within an urban signal system. Identifies the various at-grade crossing types that can exist for a LRTS, the operating characteristics of light rail vehicles, and the use of control devices at at-grade crossings. Summarizes both the priority strategies used by transit agencies and the methods of evaluation used to assess the impacts of LRTS.

Page 31 - ... designed primarily to serve as a vehicle for testing relatively complex network control strategies under conditions of heavy traffic flow. It is particularly appropriate to the analysis of dynamically-controlled traffic signal systems based upon realtime surveillance of network traffic movements. It may also be used, however, to address a variety of other simpler problems, including the effectiveness of conventional traffic engineering measures (eg, parking and turn controls, channelization,...
Page 24 - Time-based coordination is a relatively inexpensive means of allowing traffic signals on the LRT corridor to be synchronized with either adjacent signals on the corridor or signals on the cross street, or both, depending on the cycle length requirements at different times of the day and days of the week.
