基于随机用户平衡的混合交通网络流量分离模型

Mixed Traffic Network Flow-Split Model Based on Stochastic User Equilibrium

考虑了影响出行者交通选择行为的主要因素(时间、费用、方便性、舒适性等),分析了在多种交通方式(私家车、出租车、公交车、轨道交通以及自行车等)存在条件下城市交通网络中出行者交通选择行为,包括交通方式选择和出行路径选择,并基于随机用户平衡(SUE)理论构造了城市混合交通网络的流量分离和分配综合模型及求解算法。最后通过一个简单算例,得到了当各种影响因素变化时,各种交通方式的流量变化情况。

Authors analyzed the basic factors （including time, cost, convenience and comfort） that influenced passengers＇ choice behaviors under the condition of multi-mode （including car, taxi, bus, track and bike） traffic network. A flow split model and its algorithm for urban mixed network were presented based on stochastic user equilibrium （SUE） theory. Finally, the applications of the model and its algorithm were illustrated with a simple example. By the method of sensitivity analysis, the changes of different traffic mode flows were obtained with the changes of the factors that influenced the passengers＇ choice behaviors.
