Incident reports and traffic regulations (EVIS.AT): accidents, roadworks, closures with time span

GET /v1/traffic/incidents

Active reports (active=false: also ended and future), filterable by area, road (road, road_class), route, type and time window. Sorted by importance (closures and binding reports first, then motorways, expressways, federal and state roads, then start), paged with limit and cursor (total, next_cursor, next as relative URL, next_offset).

Mehr

Roadworks on motorways and expressways carry lane details from ASFINAG (lanes). mandatory=true: binding (router: closure), show the text unchanged. Geometry along GIP edges. Data source: ASFINAG / EVIS.AT (CC BY 4.0), road network GIP.at (CC BY 4.0); attribution required.

Parameter

Name	Ort	Typ	Standard	Beschreibung
`bbox`	query	string	–	west,south,east,north; optional
`planned`	query	string	–	true: planned only, false: unplanned only
`road`	query	string	–	Road number, normalized: A1, A 1 and A01 are the same; also S1, B99, L347
`road_class`	query	string	–	Comma-separated: motorway (A), expressway (S), federal (B), state (L)
`active`	query	string	`with from/to`	false: also inactive (default with from/to)
`type`	query	string	–	Comma-separated: accident, congestion, construction, lane_restriction, road_closure, road_hazard, miscellaneous
`from`	query	string	–	Window start (UTC, YYYY-MM-DD or YYYY-MM-DDTHH:MM[:SS]Z): incidents still valid afterwards
`to`	query	string	–	Window end (UTC): incidents starting before
`route`	query	string	–	Route corridor: encoded polyline (like geometries=polyline6 or polyline) or GeoJSON LineString; result sorted by position on the route
`route_precision`	query	string	–	6 (default) or 5
`buffer`	query	string	`25`	Corridor half-width in meters, 1 to 1000, default 25
`sort`	query	string	`with route`	importance (default): closures and binding reports first, then road class A, S, B, L, then start; route (default with route): position on the route
`limit`	query	string	`500`	At most this many features, 0 to 1000, default 500
`cursor`	query	string	–	Page marker: next_cursor of the previous response
`offset`	query	string	–	Skip features (alternative to cursor)
