Which units of measure are used in the Here Traffic Flow API


I read the developer documentation but still I can't find which units are used for speedFlow speedUncapped location length, etc. The API response for speeds are in the range of 2.5-3.7, too low to be miles per hour. Does anyone know which units are used in the API response. They don't offer tech support for trial accounts. Thank you.

I read the developer documentation https://developer.here.com/documentation/traffic-api/dev_guide/index.html


Solution

  • According to Here Traffic API v7 - Speeds

    A current flow object contains 3 speed values:

    •   freeFlow - the reference speed (in meters per second) along the roadway when no traffic is present.
    •   speed - the expected speed (in meters per second) along the roadway; will not exceed the legal speed limit.
    •   speedUncapped - the expected speed (in meters per second) along the roadway; may exceed the legal speed limit.
