Abstract
The Interstate-24 MObility Technology Interstate Observation Network (I-24 MOTION) is a new instrument for traffic science located near Nashville, Tennessee. I-24 MOTION consists of 276 pole-mounted high-resolution traffic cameras that provide seamless coverage of approximately 4.2 miles I-24, a 4-5 lane (each direction) freeway with frequently observed congestion. The cameras are connected via fiber optic network to a compute facility where vehicle trajectories are extracted from the video imagery using computer vision techniques. Approximately 230 million vehicle miles of travel occur within I-24 MOTION annually. The main output of the instrument are vehicle trajectory datasets that contain the position of each vehicle on the freeway, as well as other supplementary information vehicle dimensions and class. This article describes the design and creation of the instrument, and provides the first publicly available datasets generated from the instrument. The datasets published with this article contains at least 4 hours of vehicle trajectory data for each of 10 days. As the system continues to mature, all trajectory data will be made publicly available at this http URL.

I-24 Motion是位于新泽西州纳什维尔附近的一个 traffic 科学仪器,由 276 个高清晰度杆式交通摄像头组成,能够提供无缝覆盖 I-24 高速公路大约 4.2 英里的覆盖。该高速公路是 4-5 车道(每个方向)的经常拥堵的高速公路。摄像头通过光纤网络连接到一个计算设施,使用计算机视觉技术从视频图像中提取车辆轨迹。每年,I-24 Motion 内大约 230 亿英里的车辆行驶。仪器的主要输出是车辆轨迹数据集,其中包括每个车辆在高速公路上的位置,以及其他补充信息,如车辆尺寸和类别。本文介绍了仪器的设计和创建,并提供了从仪器中产生的第一批公共可用数据集。本文发布的数据集包含每 10 天至少 4 小时的车辆轨迹数据。随着系统的不断发展,所有轨迹数据都将在 this http://URL 上免费提供。
