摘　　要：提出交通网络中交通分配和信号配时的组合模型.模型被表示为两层规划.低层表示具有排队约束的Wardrop均衡模型,预测驾驶员对信号控制模式如何响应.上层确定最优信号控制以达到网络出行时间最小.The study presents a combined model for traffic assignment and signal time optimization in congestion transportation networks. The model is formulated as bi-level programming problem. The lower-level problem represents Wardrop＇s user equilibrium model, which incorporates drivers＇ reaction to a given signal control pattern. The upper-level problem is to determine an optimal green split that minimizes the system objective function of total network travel time, taking account of drivers＇ route choice behavior in response to signal split changes.

关 键 词：交通网络 均衡分配 信号控制 绿信比
