摘要:

基于“基础设施即服务”的理念研究区域城际铁路规划问题,精准考虑带时间窗的个体出行特征和运输服务供给,构建时空网络联系基础设施、服务供给和出行需求3个维度。在所有路段存在的前提下,考虑城际铁路、城市轨道交通和城市道路等基础设施及其运输服务供给,为每类出行者生成满足其出行时间窗的备选出行链集合,以所有出行者广义费用和总投资费用加权和最小为优化目标,构建整数线性规划模型。在含有物理路段相同、服务供给相同的条件下,采用相同规模,但具有不同特征的出行需求构建3种不同场景进行优化对比,验证所提出方法的价值和有效性。结果表明,本文提出的规划方法在有效满足精细化出行需求的同时,有助于实现投资效益最大,为区域城际铁路规划提供了新思路。

Abstract:

This paper considers the concept that Mobility as a Service (MaaS) and investigates the intercity railway network design problem. The travel demand with individual features and the transport services with time windows are taken into full considerations. Transportation infrastructure, transport services, and travel demand are connected on a space- time network. Assuming that all links exist, the study takes intercity railway, urban rail transit, and road infrastructures and services into account, and obtains several feasible paths from the origin to destination within the travelers' time window for each type of travelers. The integer linear programming model is then designed to minimize the total generalized cost for all travelers and investment on the network. With identical physical links and transport services, the study analyzes three scenarios with same number of travelers and different demand features and verifies the significance and effectiveness of the model. The results show the proposed intercity railway planning method well reflects different types of travel demand and maximize total benefits in terms of travel time and investment, which also provides a new perspective for regional intercity railway planning
