| 摘 要： | 提出一种基于车载无线通信模块的交通流监测原型系统,该系统将行驶中载有无线通信模块的车辆视为移动检测节点,以很小的代价实现对交通信息的获取.在此基础上提出一个具体应用:利用基站对道路上载有通信模块车辆的检测,结合设计的基于结果反馈的自适应Kalman滤波算法,及时准确地完成对路段上交通流量的检测.此外,还基于元胞自动机理论搭建了仿真平台,并验证了算法的有效性.

| Abstract: | A prototype of traffic flow monitoring system based on vehicle wireless communication module was put forward.Each moving vehicle which was equipped with the wireless communication module in this system was regarded as a moving sensor to acquire traffic information with low cost.On this basis,one concrete application was proposed:a base station detects the vehicle with wireless communication module,and estimates the traffic volume through adaptive Kalman filtering based on the feedback of estimation result.A... |
