What is the Traffic API?
HERE Traffic API is a RESTful API that provides traffic flow and incidents information and map tiles.
To obtain traffic data via the HERE Traffic API, it is necessary to formulate a request that combines the URL and a set of parameters to specify the required response.
The HERE Traffic API encompasses services outlined below.
Traffic Incident Data
The API provides aggregated information about traffic incidents in XML or JSON, including the type and location of each traffic incident, status (whether it is still active), start and end time, and other relevant data.
Traffic Map Tile Overlays (Traffic Tiles)
The Traffic API delivers pre-rendered map tile overlays with traffic information, ready to be displayed by mapping applications. You can request map tiles that show traffic data for a specific area.
Traffic Flow Data
The service offers access to real-time traffic flow data in XML or JSON, including information on speed and congestion for the region(s) defined in each request, and can deliver additional data such as the geometry of the road segments to which the flow data relate.
Traffic Flow Availability
The service allows client applications to access the general traffic information either specified by a map segment (defined as a map view), or in general for the whole world (without the map view).
