Camera Traffic Counts

Traffic count data collected from the several GRIDSMART optical traffic detectors deployed by the City of Austin. ***This dataset is no longer updated because these devices are no longer maintained*** The Travel Detectors dataset ( https://data.austintexas.gov/Transportation-and-Mobility/Traffic-Detectors/qpuw-8eeb ) is related to this dataset using the 'ATD Device ID' field. The Travel Detectors dataset provides more information on device location and status. The average speed measurements may not have been calibrated for all intersections. All measurements have been collected using automated machine vision processes and have not been validated.

本数据集为奥斯汀市部署的多台GRIDSMART光学交通检测器所采集的车流量统计数据。***本数据集现已停止更新，因相关设备不再进行维护。***Travel Detectors数据集（链接：https://data.austintexas.gov/Transportation-and-Mobility/Traffic-Detectors/qpuw-8eeb）与本数据集通过"ATD设备ID"字段关联。该数据集提供了更多关于设备位置与运行状态的信息。部分交叉口的平均车速测量数据可能未经过校准。所有测量数据均通过自动化机器视觉流程采集，且未经过有效性验证。
