Street routing

Calculate a convergence point

Find the point where routes from several locations converge with least total cost. Takes the same request as /route. trip is the route from the first location to that point, and alternates holds the routes from each of the other locations to the same point, in request order.

Request body

costing'auto' | 'bicycle' | 'pedestrian' | 'truck' | 'bus' | 'taxi' | 'motor_scooter' | 'motorcycle' | 'bikeshare' | 'auto_pedestrian' required

multimodal is not available. The street graph has no transit; use transit routing at /api/v2/routing/otp/plan.

format'json' | 'gpx' | 'osrm' | 'pbf' | 'geotiff' | 'mvt'

Not all formats are supported by all endpoints, e.g. geotiff is isochrone-only.

idstring

Arbitrary request identifier echoed in the response.

languagestring

BCP47 locale for narrative output. See locales/ for supported values.

units'km' | 'miles' | 'mi'
admin_crossingsboolean

When true, the route summary includes admins (array of administrative regions the route passes through) and admin_crossings (array of objects with from_admin_index, to_admin_index, from_shape_index, and to_shape_index indicating where and along which edge an administrative boundary is crossed).

alternatesinteger

Number of alternative routes to return. Forced to 0 for more than 2 waypoints.

banner_instructionsboolean

Include OSRM-format banner instructions, if format = osrm.

directions_type'none' | 'maneuvers' | 'instructions'
elevation_intervalnumber

Elevation sample interval in meters along the path. 0 = no elevation.

linear_referencesboolean

Include base64-encoded OpenLR references per edge in the response..

prioritize_bidirectionalboolean

Prefer bidirectional A* even when date_time.type={depart_at,arrive_by,current} in /route, or prefer CostMatrix over TDMatrix when calling /sources_to_targets

roundabout_exitsboolean

When true, exit instructions at roundabouts are added to the output.

shape_format'polyline6' | 'polyline5' | 'geojson' | 'no_shape'

Not all formats are supported by all endpoints, e.g. no_shape is not valid for isochrone.

turn_lanesboolean

When true, each maneuver may include a lanes array describing lane-level guidance: possible directions and which lanes are valid or active for following the maneuver.

voice_instructionsboolean

Include OSRM-format voice instructions, if format = osrm.
