Voyage Volume
The /arterial/api/voyagevolume endpoint returns a set of traffic volume data for Portland, Oregon. The returned data is grouped by its controller_id attribute and broken up by system detector count within that grouping. Due to the quantity of data in the database, API calls to this endpoint must be constrained within a date range through the use of the start_date and end_date parameters in order to reliably return any data.
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 Voyage Volume section of the Other Download Categories dropdown menu on the Downloads page.
