基于时空消耗理论的城市交通结构数学规划优化模型研究

A Mathematical Programming Model of Optimizing Urban Passenger Traffic Structure Based on Time-space Consumption Theory

在分析各交通方式出行效率差异性基础上,立足于城市客运系统的基本功能,建立了城市地面上客运交通结构线性规划模型。模型以各种交通方式时空消耗最小化为目标,考虑了城市道路系统要求、出行者要求、城市客运系统要求和交通方式发展规模4个方面约束,最后比较了本文模型与其他文献模型的区别。

Urban traffic structure is the core and key factors that determine the sustainable development of urban traffic system. By analyzing the difference of all traffic modes in transportation efficiency and based on the basic function of urban passenger traffic system,the paper proposed a lineal programming model of optimizing urban passenger traffic structure. The objective of the model is minimizing the time and space consumption of the urban passenger traffic system. The constraints include four aspects：urban road system, the passengers,urban passenger traffic system and the scale of each traffic mode. In the end ,the difference between the model and others＇ model was compared.
