点击右侧的“导出”以下载车辆轨迹数据。相关元数据及其他数据可于下方“附件”中下载。下一代仿真（NGSIM）项目的研究人员在加利福尼亚州洛杉矶市的南行US 101公路与兰卡斯特大道、加利福尼亚州埃默里维尔市的东行I-80公路以及佐治亚州亚特兰大市的皮奇树街采集了详细的车辆轨迹数据。数据通过同步数字摄像机网络获取。NGVIDEO是为NGSIM项目开发的定制化软件应用，用于从视频中提取车辆轨迹数据。该车辆轨迹数据每十分之一秒记录一次研究区域内每辆车辆的精确位置，从而获得详细的车道位置信息及与其他车辆的相对位置关系。点击下方“显示更多”按钮，可获取本数据集的额外上下文数据和元数据。如需特定站点的NGSIM视频文件数据集，请参见以下链接：- NGSIM I-80视频：https://data.transportation.gov/Automobiles/Next-Generation-Simulation-NGSIM-Program-I-80-Vide/2577-gpny - NGSIM US-101视频：https://data.transportation.gov/Automobiles/Next-Generation-Simulation-NGSIM-Program-US-101-Vi/4qzi-thur - NGSIM 兰卡斯特大道视频：https://data.transportation.gov/Automobiles/Next-Generation-Simulation-NGSIM-Program-Lankershi/uv3e-y54k - NGSIM 皮奇树街视频：https://data.transportation.gov/Automobiles/Next-Generation-Simulation-NGSIM-Program-Peachtree/mupt-aksf

Click “Export” on the right to download the vehicle trajectory data. The associated metadata and additional data can be downloaded below under "Attachments". Researchers for the Next Generation Simulation (NGSIM) program collected detailed vehicle trajectory data on southbound US 101 and Lankershim Boulevard in Los Angeles, CA, eastbound I-80 in Emeryville, CA and Peachtree Street in Atlanta, Georgia. Data was collected through a network of synchronized digital video cameras. NGVIDEO, a customized software application developed for the NGSIM program, transcribed the vehicle trajectory data from the video. This vehicle trajectory data provided the precise location of each vehicle within the study area every one-tenth of a second, resulting in detailed lane positions and locations relative to other vehicles.
