摘要

This study developed an approximate analytical model to design feeder bus transit (e.g. shuttle bus, minivan) services along a trunk line (e.g. metro rail and light rail) whose stations and line alignment are pre-determined. Specifically, an optimization model is developed to identify the density and frequency of feeder bus services that minimizes the total cost of the trunk-feeder system (sum of operating cost and user cost) subject to vehicle capacity constraints. The model is applied using the data from Purple Line Light Rail (LRT) system in Maryland, U.S.A. The results demonstrate that the developed model provides a useful tool to generate the optimal number of feeder bus lines and the best frequency of feeder service along the Purple Line corridor.
