信号交叉口车辆通行轨迹数据集

信号交叉口车辆通行轨迹数据集由吉林大学利用视频轨迹提取软件Tracker进行无人机航拍视频数据中车辆轨迹数据的手动提取，共得到长春市4个信号控制交叉口车辆通行案例36组，其中有16组直行通行案例，16组左转案例和4组右转案例。通过使用Matlab程序，对公开轨迹数据集Waymo中的轨迹数据进行通行车辆的数据筛选、滤波、缺失值和异常值处理等工作，提高数据质量，保证数据精度。共得到3个交叉口的通行案例4组，其中直行通行案例2组，左转和右转通行案例各1组。Jilin University manually extracted the vehicle trajectory dataset for signalized intersections from unmanned aerial vehicle (UAV) aerial video data using the video trajectory extraction software Tracker. A total of 36 vehicle traffic cases from 4 signal-controlled intersections in Changchun City were obtained, including 16 straight-through traffic cases, 16 left-turn cases, and 4 right-turn cases. Additionally, trajectory data from the public Waymo trajectory dataset was processed via Matlab programs, covering vehicle screening, filtering, missing value handling, and outlier removal to improve data quality and ensure data accuracy. For the processed Waymo dataset, 4 traffic cases from 3 intersections were acquired, with 2 straight-through cases, 1 left-turn case, and 1 right-turn case respectively.
