Development of a Location Method for Urban Public Transit Network based on the Hub and spoke Network Structure

摘要

This paper presents a location method for urban public transit (PT) network based onthe hub and spoke network structure model. The proposed method integrates the PTlines with the transfer hubs. PT lines fall into four major service levels: the subwayservice, the bus rapid transport (BRT) service, the bus service, and the feeder busservice. Transfer hubs fall into three major categories: intermodal terminals, transfercenters and transfer stations. Every level of PT lines is located by connecting thedifferent classes of transfer hubs. The optimization objectives, the constraints and theprocedures for PT lines location are present, and they are different for every level PTservice. The design and implementation of the proposed method are illustrated by acase study for Fuzhou city; the proposed allocation method offers a new approach forincreasing the PT level of service of a high-density city. The procedure for allocatingPT lines is more practical and maneuverable.
