车路协同下高速公路运行态势监测方法

Monitoring method for traffic situation of highway under vehicle-infrastructure cooperation

为了监控高速公路交通状况,构建了车路协同下高速公路运行态势的监测与评定一体化方法.借助新一代信息通信技术和结合高速公路车辆行驶态势,在分析道路交通事故主要特征的基础上,利用车路协同技术构建高速公路运行态势的监测指标体系.以行驶中的车辆为信息感知对象,依据大数据技术,利用不确定性数学方法建立高速公路运行态势的评估模型.结果表明,车路协同下评估模型不但能最大可能地控制高速公路系统中的不安全行为,而且能最大限度地解决车、路、环境等诸要素的协同问题.通过对复杂交通环境下高速公路运行态势进行等级界定,可为用户提供安全、舒适、智能、高效的驾驶感受与交通服务.采用该评估模型对江苏省境内19条高速公路运行态势聚类分析,所得结果符合江苏省高速公路实时运行情况.该监测与评估方法提高了高速公路运行态势研究的实时性和准确性,使高速公路系统运行管理达到高效化和安全化.

To monitor the traffic condition of highway,an integrated method for monitoring and evaluating the running situation of the highway under the vehicle-infrastructure cooperation was constructed.With the new generation of information and communication technology and combined with the driving situation of highway vehicles,by analyzing the main characteristics of road traffic accidents,the monitoring index system of the highway operation situation was constructed.The results show that the model can control the unsafe behavior in the highway system and solve the cooperative problems of vehicles,roads and environments.By defining the operating situation of highway in the complex traffic environment,it can provide users with safe,comfortable,intelligent,and efficient driving feeling and traffic service.Through the cluster analysis of the operation situation of 19 highways in Jiangsu Province,the results are in agreement with those obtained under the real-time operation conditions of Jiangsu highway.The monitoring and evaluating method improves the real-time and the accuracy of the highway operation situation,and makes the highway system operation management achieve the high efficiency and the safety.
