MODELS FOR ASSESSING TRIP DEPENDABILITY IN AUTOMATED GUIDEWAY TRANSIT NETWORKS

Equipment failures and how to correct them are significant factors affecting the quality of service of Automated Guideway Transit (AGT) systems. The network configuration, subsystem failure rates, and recovery modes interact to provide the operational configuration that passengers ultimately view in terms of the ability of the AGT system to provide reliable service for their trip. This report describes a procedure that permits evaluation of the Group Rapid Transit networks in terms of trip dependability. The model uses a flow representation of vehicle traffic determined by network topography, demands for travel, and operational service policy. The model has its most useful application in the intermediate design stage where there are tradeoffs to be evaluated.
