Detector Metadata
The /highways/api/detectormetadata end point returns station data for each individual detector in the network, sorted by station number. This information can be constrained to a date or a range of dates using the start_date and end_date parameters; applying this constraint will return only stations active within that range of dates.
This endpoint returns data in JSON format by default. An overview of the data returned by this endpoint, including attribute descriptions, can be found on the Downloads page, in the Detector Metadata section of the Highway Data dropdown menu on the downloads page.
