A MODEL TO OPTIMIZE INTERSTATION SPACINGS OF URBAN RAIL RAPID TRANSIT SYSTEMS

An analytical model for determining the optimal station spacings of the RRT system developed by using differential calculus method is presented. Specific cost functions are established for both users and operators in building the model. The model is to find the optimal interstation spacing so that the total social cost is minimized. The results of sensitivity analysis show that the optimal station spacing is more sensitive to some factors such as passenger out-of-vehicle travel time, daily passenger demand, route length and stationing cost but less sensitive to others. In addition, it is found that the effects of out-of-vehicle travel time is more significant than that of in- vehicle travel time. This implies that the transit users are reluctant to walk long distances to use transit. Hence in determining station sites a convenient access to the station should be provided. The number of the covering abstract of the conference is IRRD no 266527.
