摘　　要： 为了及时、准确地获取城市道路交通信息,提出了一种基于车间通信的交通信息采集方法,将具有车间通信功能的车辆视为路网中的移动传感器节点;路旁基站通过对节点采集到的交通数据进行分析,得到路段实时交通状态。另外,还设计了基于上述方法的无线交通信息服务系统(WTISS)原型,同时结合Paramics、NS2、Matlab、MySQL等工具完成了WTISS仿真系统,并在该仿真系统上验证了本文方法的正确性。 In order to acquire urban traffic information timely and accurately,a method of collecting traffic information based on inter-vehicle communication was put forward.All the vehicles which can transmit and receive data by wireless communication were regarded as moving sensors on traffic network.Road-side station can get traffic status by analyzing data collected by equipped vehicles.Moreover,a prototype system of Wireless Traffic Information Service System(WTISS)was designed,and WTISS simulation system based on Paramics,NS2,Matlab and MySQL was constructed.The method of collecting traffic information mentioned above was verified on this simulation system.
