Raster Incident Tiles

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.

You can easily run this and other endpoints.

1. Go to the TomTom API Explorer page.
2. Click an endpoint.
   1. Click Try it out.
   2. Enter/select all required parameter values and any optional parameter values.
   3. At the bottom of the form, click Execute.
3. Review the Response.
