This research proposes a new traffic assignment method on the hybrid road network which consists of two types of links, one is "aggregate link" that represents many routes and mainly deals with streets, the other is "arterial link" that represents the road section and mainly indicates arterials. The simplified network can be formed with smaller number of links comparing to one including all roads, arterials and streets. This research shows the equivalence between the assignment on the simplified network and on the network of all roads on the assumption and using the special utility function in the route choice model. As for the assumption, the study is assuming that the cognitive travel time of all routes from Origin to Destination is the same within the streets area, which is surrounded by arterial links. On the other hand, the special utility function is adopted that can be divided into several road sections. Moreover, a traffic simulation model is established, which can estimate dynamic user equilibrium flow approximately on the hybrid road network.

本文提出了一种新的混合路网交通分配方法，该方法由两类路段组成，一类是“聚合路段”，代表多条路线，主要处理街道;另一类是“主干路段”，代表路段，主要表示干线。与包括所有道路、干线和街道的网络相比，简化网络可以用较少数量的链路形成。在路径选择模型中，假设并使用特殊的效用函数，证明了简化网络上的分配与所有道路网络上的分配是等价的。至于假设，本研究假设从原点到目的地的所有路线的认知旅行时间是相同的街道区域内，这是由动脉连接包围。另一方面，采用了特殊的效用函数，可以划分为多个路段。此外，建立了一个交通仿真模型，该模型可以近似估计混合路网上的动态用户平衡流量。
