Supposing that the travel cost on the paths and the congestion degree on the key links were considered by the urban travelers, a price-congestion mixed dynamic evolution model was established based on analyzing the equilibrium flow model. The model was based on the economics theory of non-Walrasian equilibrium method and by simulating the traveler's route choice behavior following the economical concept of market exploration process, the equivalency of model stability and equalization was verified. The evolution model was simulated by using a s...

基于经济学非瓦尔拉斯均衡理论,采用经济学中市场摸索过程模拟出行者路径选择行为;假设城市出行者在路径决策过程中,考虑路径出行时间和关键路径拥挤程度的共同影响,以价格拥挤混合均衡交通流模式为基础,建立了一种价格-拥挤混合调节的非均衡网络交通流动态演化模型,并验证了模型稳定状态与均衡的等价性;基于简单的测试网络和中型路网,对演化模型进行了模拟,描述了非均衡网络交通流的演化过程与非均衡状态下交通网络的整体表现。研究结果表明:时间价格调节模型的演化结果符合经典的Wardrop第一原理,拥挤数量调节的结果使得OD间各路径上关键路段的拥挤程度一致,价格-拥挤混合调节的结果会使路径流...
