Traffic

Traffic data covers the motorway and expressway network (ASFINAG, EVIS.AT) and planned roadworks on other roads. Requests are in the search zone, 10 per second, and need a token (Access and limits); curl samples send it as a header, browser samples as access_token. The map source below takes the token from the transformRequest of First map.

List incidents

const url = "https://api.mapx.at/v1/traffic/incidents?bbox=16.0,48.0,16.8,48.5&type=road_closure,construction&limit=20&access_token=YOUR_TOKEN";
const { features, total, next_cursor } = await (await fetch(url)).json();
for (const f of features) console.log(f.properties.road, f.properties.type, f.properties.text);

Filters: bbox, road (A1, A 1 and A01 are the same road), road_class (motorway, expressway, federal, state, comma-separated, for A, S, B and L roads), type (accident, congestion, construction, lane_restriction, road_closure, road_hazard, miscellaneous), planned=true|false, and a time window with from and to (UTC). By default only active reports are returned; active=false adds ended and future ones. A report with mandatory: true is binding; show its text unchanged.

Results are sorted by importance: closures and binding reports first, then motorways, expressways, federal and state roads, then by start. Page with limit (default 500, maximum 1000) and cursor: pass next_cursor from the response, or follow next, until next is null. total is the number of matches. Bad values for road, road_class, type or cursor return a 400 problem response.

curl -s -H "Authorization: Bearer YOUR_TOKEN" "https://api.mapx.at/v1/traffic/incidents?road=A1&road_class=motorway&limit=100" | jq '.total, .next'

Lane details on motorways

Roadworks on motorways and expressways carry lanes from ASFINAG: one entry per direction and carriageway with the closed lanes (right, middle, left, hard_shoulder), the number of open lanes (open) out of original, contraflow, road_closed and the temporary speed_limit_kmh. direction is aligned (with increasing road kilometers) or opposite. sources lists where a report comes from (evis, asfinag); source names the dataset (evis-planned+asfinag when both match, asfinag-roadworks for roadworks only ASFINAG reports). The text of an EVIS report is never changed.

const url = "https://api.mapx.at/v1/traffic/incidents?road=A12&type=lane_restriction&access_token=YOUR_TOKEN";
const { features } = await (await fetch(url)).json();
for (const f of features) for (const l of f.properties.lanes) console.log(f.properties.road, l.closed, l.open, l.speed_limit_kmh);

Incidents along a route

Pass the route as route (encoded polyline or GeoJSON). Results are sorted by position on the route. For long routes use POST with a JSON body.

curl -s -H "Authorization: Bearer YOUR_TOKEN" -X POST https://api.mapx.at/v1/traffic/incidents -H "Content-Type: application/json" -d '{
  "route": { "type": "LineString", "coordinates": [[16.37, 48.21], [16.3, 48.19]] },
  "type": "road_closure,construction", "buffer": 50
}' | jq '.total'

buffer is the corridor half-width in meters (1 to 1000, default 25).

Show traffic on the map

map.on("load", () => {
  map.addSource("traffic", { type: "vector", url: "https://api.mapx.at/v1/traffic/tiles.json" });
  map.addLayer({ id: "traffic", type: "line", source: "traffic", "source-layer": "traffic",
                 paint: { "line-width": 4, "line-color": "#e11d48" } });
});

The style traffic-day already contains the layer. Tiles are in the static zone (5 per second); let the client cache them.

Route with traffic

GET /v1/directions/driving-traffic/{coordinates}

The route avoids current closures and lists incidents in legs[].incidents. Use incidents=true to get the list with other car profiles.
