城市交通网络均衡问题的算法分析与应用研究

The Researches and Applications for the Urban Transportation Network Equilibrium Question

随着世界上大多数城市的交通条件的日益恶化,如何有效地模拟和解决拥挤和出行决策间的相互作用,从而获得整个城市交通网络的交通流模式,在国内外产生了一系列分析方法。在对交通网络分配模型进行系统综述地基础上,重点讨论了固定需求下的均衡配流问题。通过具体的算例,将容限配流法、比例配流法和方向搜索法进行对比分析,证明了方向搜索法在求解标准均衡配流解上的优越性。

With traffic conditions in most cities worsening, a series of analysis methods have been studied at home and abroad to simulate and solve the interaction between congestion and travel decision -making effectively, then obtain the flow patter throughout the whole urban network. The standardized User - equilibrium model and its solution algorithm in detail are discussed. The paper aims to discuss the equilibrium assignment. By contrasting and analyzing, the direction search method is found the best. The conclusions are instructive to the network assignment.
