| 摘 要： | 行人过街交通特性参数是开展“以人为本”交通管理与控制工作的基础数据.针对现有的行人过街交通特性参数调查方法在行人交通密度与运动空间调查中存在的局限性,文章提出基于低空多旋翼无人机(UAV)辅助城市路口行人过街交通特性参数调查方法,利用无人机航拍视频图像,采用人工交互作业模式可以快速地提取路口行人过街速度、行人交通密度与运动空间等参数。以深圳市10个典型灯控路口为例进行测试,结果表明该方法具备可行性,统计获得深圳市灯控路口行人过街平均步速为1.52 m/s,略高于哈尔滨、北京、长春等城市的同类统计结果.

| Abstract: | Pedestrian crossing traffic characteristic parameters are the basic data for carrying out"people-oriented" traffic management and control.In view of the limitations of the existing survey methods in the investigation of pedestrian traffic density and movement space,this paper proposes a method based on the low altitude multi-rotor unmanned aerial vehicle(UAV) assisted pedestrian crossing traffic characteristic parameters survey method at urban intersections,which uses UAV aerial video images and adopts manual interactive operation mode to quickly extract the pedestrian crossing speed,the pedestrian traffic density and movement space.Taking 10 typical signal controlled intersections in Shenzhen city as examples,the results show that the method is feasible,and the average walking speed of pedestrians at light controlled intersections in Shenzhen is 1.52 m/s,slightly higher than that of Harbin,Beijing,Changchun and other cities in China. |
