州际24移动技术州际观测网络(I-24 MOTION)是位于田纳西州纳什维尔附近的一种新的交通科学仪器。I-24 MOTION由276个安装在杆上的高分辨率交通摄像机组成,可无缝覆盖约4.2英里的I-24,这是一条4-5车道(每个方向)的高速公路,经常出现拥堵。摄像机通过光纤网络连接到计算设施,在计算设施中使用计算机视觉技术从视频图像中提取车辆轨迹。每年大约有2.3亿英里的车辆行驶在I-24 MOTION内。该仪器的主要输出是车辆轨迹数据集,其中包含高速公路上每辆车的位置,以及其他补充信息,如车辆尺寸和类别。本文描述了该仪器的设计和创建,并提供了从该仪器生成的第一个公开可用的数据集。本文发布的数据集包含10天中每天至少4小时的车辆轨迹数据。随着系统的不断成熟,所有轨迹数据都将在i24motion.org上公开。
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 is vehicle trajectory datasets that contain the position of each vehicle on the freeway, as well as other supplementary information such as 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 i24motion.org.
