| 摘 要： | 从道路使用率、出行时间成本、环境保护三方面平衡交通效益出发,建立在饱和度约束下以通行能力、出行者平均延误、尾气排放量作为性能指标的平面交叉口信号控制多目标优化模型;模型可根据交通流状态的不同对控制目标有所侧重;最后运用遗传算法对模型进行优化。算例分析表明,该模型能较好的适应交通流状态的变化,可获得更好的交通控制效果。

| Abstract: | Based on using rate of the road, traveler time cost, environment protection comprehensive balance of traffic efficiency, the paper presents a multi-objective signal control optimization model with traffic capacity, traveler delay and exhaust emission as the optimization objectives, and saturation degree is taken as restrictions. The method can adjust the weight of performance indexes according to traffic flow state. The multi-objective model is solved by genetic algorithm. The result shows that the model can adapt the traffic flow state well and improve the traffic control effectively. |
