摘要
针对当前我国城市交通控制对静动态道路交通信息一体化采集存在的难点,设计运用低空多旋翼无人机(multi-rotor UAV)加载高清摄像机及其相应的视频分析系统采集交通控制区域内交通控制评价与优化所需数据,在此基础上利用VISSIM软件进行城市交通控制效果的评价与配时方案优化,并以深圳市沙河西路一西丽湖路交叉口为例进行验证。结果表明,基于UAV/VISSIM的城市交通控制评价与优化方案具有可行性,优化后该路口的服务水平由目前的E级提升至C级,有效提高城市交通控制评价和整体工作效率。
In view of the difficulties of integrated collection of static and dynamic road traffic information in China's urban traffic control,this paper designs to use the low altitude multi-rotor unmanned aerial vehicle(UAV)loaded with high-definition camera and corresponding video analysis system to collect the data needed for traffic control evaluation and optimization in the traffic control area.On this basis,VISSIM is used to complete the evaluation of urban traffic control effect.Then,taking the intersection of Shahe West Road and Xili Lake Road in Shenzhen as an example,the method is verified.The experimental results show that the evaluation and optimization scheme of urban traffic control based on UAV/VISSIM is feasible.After optimization,the service level of the intersection is upgraded from the current E level to the C level,which can effectively improve the overall efficiency of urban traffic control evaluation and optimization.
