Resource title	Traffic information messages
Description	Traffic information messages are available in two formats: the DATEX II standard and a simpler Simppeli JSON format that follows the GeoJSON standard and includes the geometry of the message. Simppeli JSON can be retrieved without area geometries to reduce data size, or geometries can be downloaded separately via an interface and combined with the message. Traffic messages use the TMC/ALERT-C location referencing system to indicate the geographical position of incidents, and time fields follow the ISO 8601 format in UTC. Message types include special transports (EXEMPTED_TRANSPORT), road works (ROAD_WORK), traffic announcements (TRAFFIC_ANNOUNCEMENT), and weight restrictions (WEIGHT_RESTRICTION).
