基于出行链理论的UE模型构建

Construction of User Equilibrium model based on trip-chaining

为使传统用户平衡配流模型所得结果更加符合出行者实际出行行为,在分析出行链和传统用户平衡配流两大理论的基础上,将传统UE模型中的路段流量转变为出行链的流量,构建了基于出行链的UE模型;通过分析比较运用传统算法与有效集算法求解平衡配流问题,得出有效集算法更适于求解构建的模型。

In order to make the traditional User Equilibrium assignment model results more in line with the traveler actual travel behavior,based on the analysis of trip-chaining theory and traditional user equilibrium assignment theory,road traffic flow of the traditional UE model was transformed into the trip-chaining flow. A UE model based on trip-chaining was constructed. Based on analysis and comparison about solving the assignment problem with traditional algorithm and active set algorithm,the active algorithm was put forward to solve the model.
