Vehicle Positions

The Vehicle Positions API is a GraphQL service that provides real-time positions and status for public transport vehicles across Norway. It enables fetching and streaming live vehicle data including location, delays, occupancy, and journey information.

API Reference

WebSocket Subscriptions

For real-time streaming updates, the API provides GraphQL subscriptions over WebSocket:

WebSocket URL: wss://api.entur.io/realtime/v2/vehicles/subscriptions

Subscriptions allow your application to receive continuous updates as vehicle positions change, rather than polling for data.

Example Subscription

Connect to wss://api.entur.io/realtime/v2/vehicles/subscriptions with the ET-Client-Name header.

Subscribe to vehicle updates within a geographic bounding box:

Code
subscription {
  vehicles(
    boundingBox: {
      minLat: 59.9
      maxLat: 60.0
      minLon: 10.7
      maxLon: 10.8
    }
  ) {
    vehicleId
    location {
      latitude
      longitude
    }
    bearing
    delay
    line {
      publicCode
    }
  }
}
