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 ***This dataset is no longer updated because these devices are no longer maintained*** The Travel Detectors dataset ( https://data.austintexas.gov/Transportation-and-Mobility/Traffic-Detectors/qpuw-8eeb ) is related to this dataset using the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.
