摘要
为了解决城市交通仿真模型仿真速度和仿真精确度的平衡问题,针对城市交通流运行特征,同时考虑影响交通流运行的若干因素,如车辆数目、红绿灯控制等,提出一种中观交通仿真车辆群体模法。该模型结合了宏观模型和微观模型的优点,同时对应的交通流配流算法解决了传统模型的不足,城市交通仿真实验结果表明了车辆群体模型和分配算法的合理性和有效性。
To deal with the balance between rate and accuracy for the urban traffic simulation,characteristics of the urban traffic flow are analyzed,and factors such as car number,traffic lights are also taken into consideration.The car group model of the urban traffic flow is proposed,and a traffic assignment algorithm is developed.The car group model is combined with the macro and micro traffic flow model,and the traffic assignment algorithm is used to solve the problem in traditionary OD matrix.Finally,the urban traffic simulation demonstrate the validity and efficiency of the presented method.
