基于定点检测数据的城市干道车辆轨迹重构

Signal Timing and Detector Databased Reconstruction of Vehicle Trajectories on Urban Arterials

摘要:

针对我国城市干道实际交通数据条件，通过融合定点检测器和交通信号配时数据，基于交通波动理论和交通仿真的思想，开发了一种新的车辆轨迹重构方法，克服了现有方法依赖于高频率的浮动车数据以及未考虑车辆变道和路侧出入口进出车辆干扰的缺陷，并以青岛市一条信控干道的实证数据验证了该方法的有效性.

Abstract:

Based on the shockwave theory and traffic simulation concept, this paper presents a new reconstruction method of vehicle trajectories on urban arterials with detector data and signal timing data. Unlike the existing methods, the proposed method takes into consideration the impacts of lane change and roadside entrance and exit on vehicle maneuvers without relying on highfrequency floating car data. The proposed method has been validated at a signalized arterial in Qingdao City of China.
