Incident Details

Service version: 5

Important note

This is the new and improved version (5) of the Incident Details endpoint. We highly recommend that you use this new version 5 rather than the old version 4, which we marked as deprecated.

Purpose

The Incident Details service provides information on traffic incidents which are inside a given bounding box or whose geometry intersects with it.

• The freshness of data is based on the provided Traffic Model ID.
• The data obtained from this service can be used as standalone or as an extension to other Traffic Incident services.
  • In the second case, the same Traffic Model ID should be used when calling all services, in order to grant synchronization of data between APIs.
• Apart from present incident data, it is possible to get information about planned future incidents.

Response data

Successful response

For a single request, the Traffic API Incident Details endpoint returns its response body in JSON format. The fields that appear in the JSON response depend on the value of the fields request parameter.
