摘要
为了解决交通平衡分析理论的一个难点问题即如何把车种禁行管理信息融入到交通平衡分析中来,通过定义路网出行子图空间,提出了基于路网出行子图空间上的W ardrop平衡原理并建立了相应的交通平衡分析模型.通过实例阐释了含有分车种禁行路段路网平衡交通流从W ar-drop平衡状态到出行子图空间上的W ardrop平衡状态演变的条件及演变的过程,可以看出,出行子图空间上的W ardrop平衡是比W ardrop平衡外延更广的一个概念,该方法有利于分析含有局部限制条件下交通行为的本质特征,有助于交通优化管理方案的设计.
To bring management＇ s information of partial prohibited link into method of traditional traffic flow equilibrium analysis a new conception, journey sub-graph space, is proposed in this article. Then a new kind of Wardrop equilibrium is proposed based on the journey sub-graph space, and the traffic equilibrium analysis model which confirms the rule of Wardrop equilibrium on the journey sub-graph space is built up. By using the new analysis method, the conditions and processes of state transferring from Wardrop equilibrium to Wardrop equilibrium on the journey sub-graph space are illustrated through an example. It is shown that the conception＇ extension of Wardrop equilibrium on the journey sub-graph space is larger than that of Wardrop equilibrium. With this new analysis method, many transportation management schemes might be gained.
