摘要:
为优化经济圈内客运多方式交通网络结构,建立了交通方式分担与交通分配组合模型,研究经济圈内多方式交通网络均衡时乘客的交通方式选择问题.考虑出行时间、出行费用、舒适度等影响乘客出行方式选择的因素,分析了铁路和公路2种存在主要竞争关系的出行方式的广义出行费用.结合我国经济圈内城际客运出行特征,给出了经济圈内多方式交通网络均衡条件,构建了与该均衡条件等价的变分不等式模型,设计了求解该模型的精简对角化算法.最后结合长江三角洲经济圈,应用该模型预测乘客选择铁路和公路出行方式的比例.结果表明,模型和求解算法有效,能够从用户最优的角度为合理配置经济圈内多种交通方式提供量化依据.
Abstract:
A combined modal split and assignment model is proposed for modeling passengers’ mode choices in a multimodal transportation network in an economic circle. Generalized travel cost models of highway and railway are established which incorporate the travel time, ticket fare and passenger’s discomfort. The equilibrium conditions of a multimodal transportation network in an economic circle are defined based on characteristics of passenger’s trips between cities. A variational inequality formulation is proposed to express the equilibrium conditions. The streamlined version of a diagonalization algorithm is presented to solve the model. The model and the algorithm are applied to the prediction of the ratios of passengers’ choices of railway and highway for their trips between cities in the Yangtze River Delta economic circle. The numerical results show that the model and the algorithm are effective, which can provide quantitative basis for rationally configuring the multiple traffic modes in an economic circle from the perspective of user optimum.
