Freeway trajectory recordings: on ramp accelerations and gap choices after ramp metering

This dataset contains the (frames of) videos of freeway data near an on ramp with a ramp metering. It has been used to study the acceleration of vehicles leaving the ramp metering. <br>Also some trajectories and a transformation to real-world coordinates is available. Please refer to the readme file for the content of each of the files.<br>

本数据集收录了设有匝道计量控制（ramp metering）的高速公路入口匝道周边的视频及视频帧数据，曾被用于研究驶出匝道计量控制区域的车辆加速特性。
此外，数据集还提供了部分车辆轨迹数据以及可将图像坐标转换至真实世界坐标系的变换参数。各文件的具体内容，请参阅数据集附带的自述文件（README）。
