Raster Incident Tiles

Service version: 4
Last edit: 2022.09.12

Purpose

The TomTom Traffic Tile service serves 256 x 256 pixel or 512 x 512 pixel tiles showing traffic incidents. All tiles use the same grid system. Because the traffic tiles use transparent images, they can be layered on top of map tiles to create a compound display. Traffic tiles render graphics to indicate traffic on the roads in the specified area. The Traffic incidents tiles use colors to indicate the magnitude of delay associated with the particular incident on a road segment. The magnitude of delay is determined based on the severity of traffic congestion associated with the particular incident.

Response data

Successful response

The Raster Incident Tiles API endpoint for a valid single request returns a response in PNG format. See: style examples for more information.

Error response

The Raster Incident Tiles API endpoint for an invalid single request returns a response body in XML or JSON format. By default the Error response is returned in XML format. In order to obtain the Error response in JSON format, the Accept request header with a proper value must be used. The types of the fields refer to a JSON response.
