Next Generation Simulation (NGSIM) Open Data

ITS DataHub has partnered with the Federal Highway Administration's (FHWA's) Next Generation SIMulation (NGSIM) program to make available detailed vehicle trajectory data and supporting data files along with the raw and processed video files from the NGSIM data collection efforts. Researchers for the NGSIM program collected the specified data on southbound US 101 and Lankershim Boulevard in Los Angeles, CA, eastbound I-80 in Emeryville, CA and Peachtree Street in Atlanta, GA. This article provides a brief overview of the NGSIM program data collection as well as what types of data are available on ITS DataHub. Some examples of possible uses for the data and information on how to cite the various NGSIM datasets are also included.

智能交通系统数据枢纽（ITS DataHub）已与美国联邦公路管理局（Federal Highway Administration，FHWA）旗下的下一代仿真（Next Generation SIMulation，NGSIM）项目达成合作，对外公开由NGSIM数据采集项目产出的精细化车辆轨迹数据、配套数据文件，以及原始与经处理后的视频文件。NGSIM项目的研究团队分别于美国加利福尼亚州洛杉矶的南向101号美国国道与兰克辛大道、加利福尼亚州埃默里维尔的东向80号州际公路，以及佐治亚州亚特兰大的桃树街完成了指定数据的采集工作。本文简要概述了NGSIM项目的数据采集工作，并介绍了ITS DataHub平台上可获取的各类数据类型。此外，本文还收录了该数据集的部分潜在应用场景示例，以及各类NGSIM数据集的引用规范相关说明。
