Traffic Congestion Identification Design Based on Vehicle Electronic Tags

摘要:

提出一种基于车载电子标签的交通状态判别方法;该判别方法通过在路段安装背靠背式接收机避免反向车道车辆干扰,采用有源主动电子标签扩大读写范围与精度,利用扫描区间内获得的电子标签数量、更新比率、停留时间等信息,配合交叉口信号灯状态,构建控制系统与车载电子标签的联动体系,进行交通状态,尤其是拥堵状态的判别;经VISSIM交通仿真软件的二次开发,模拟车载电子标签环境,仿真试验验证该方法可有效判别交通状态,判别的平均准确度在85%以上。

Abstract:

Traffic congestion identification design based on vehicle electronic tags is proposed. The reader which is installed on the road back to back, is used to avoid the interference from the reverse drive vehicles. And the Active electronic tag is used to expand the range and accuracy in reading and writing. In scanning of electronic tag range, the number of vehicle electronic tags, the tag’s update ratio and the travel time are obtained. In order to identify traffic status and the congestion state, the control system and the linkage of the on-board electronic tag system with the intersection light condition is established. The simulation environment is built by VISSIM with secondary development. Simulation result shows that the present methods can effectively discriminate traffic states and the average accuracy is above 85%.
