Camera Traffic Counts

Traffic count data collected from the several GRIDSMART optical traffic detectors deployed by the City of Austin.

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.

THIS DATASET IS UNDER ACTIVE DEVELOPMENT AND IS SUBJECT TO CHANGE AT ANYTIME. IT MAY CONTAIN INCOMPLETE OR INACCURATE INFORMATION

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.
