A performance assessment model for automated guideway transit systems

A computer model has been developed for the purpose of assessing the performance characteristics of Automated Guideway Transit (AGT) systems. The model is structured to provide an effective, low-cost tool for establishing the supply side characteristics of AGT systems for a variety of network configurations and demand models. Features of the model include the automatic generation of service routes and assignment of route operating frequencies and the capability to display results as well as verify user supplied network data through the use of computer generated graphics. Model outputs consist of system operational statistics, passenger service measures, system capital and operating costs, and energy utilization estimates. Applications of the model have included examinations of AGT system design requirements and cost/performance comparisons of AGT and conventional transit modes. The model has proved to be particularly useful for conducting parametric studies necessary to gain an understanding of system performance-operating policy interactions. A detailed description of the model is presented in the paper along with examples of model outputs and a discussion of computer resources required in using the model.
