The objective of the model is to assign a proportion of the zone-to-zone travel demand onto the station pairs of a planned guideway transit system. The assignment is based on trip time ration between using the existing system (so-called Feeder system) and the planned guideway system. The model output may be used as part of the data to compare different new systems operating in the same demand environment. Originally, the FSM was designed to generate patronage demand data for the automated guideway transit (AGT) system analysis. However, the FSM can be used for plannning studies for any guideway system. The modeling approach of the FSM is generic in nature; it is recommended for comparison of representative deployments only. Actually, the AGT system in the FSM is the guideway system under study (i.e., new system/service to be introduced in the community), and the feeder system is the currently existing local transit system. The FSM models the performance of both the fixed-route service operating on grid networks and the demand responsive service operating on the same network. Basically, the major function of the FSM is to assign patronage demand in a given area onto an AGT network operating in the same general area. This manual describes the organization of the model, the operational features, the required input, the procedure necessary for execution of the model, and the model output.138
