基于实时交通信息的车辆路径与调度动态仿真

Dynamic Vehicle Routing and Scheduling with Real-time Traffic Information

城市的发展导致道路交通运输问题变得越来越突出。针对这类问题,建立了一种基于实时交通信息的动态车辆路径与调度问题模型,并构建了一个动态交通仿真模型模拟真实的车辆行驶状况。通过两阶段仿真,获取车辆在道路中行驶的实际行驶时间。最后构造了一个交通网络,通过仿真试验验证提出的模型的有效性。

With the development of city construction, urban freight transport problems become more and more heavily. In order to solve these problems, a dynamic vehicle routing and scheduling model with real time information was set up and a dynamic traffic simulation model was proposed. Two-phase simulations were used to update the travel time. The models were used to a test road network. Simulation experiments verify the efficiency of the proposed model.
