General options

All OSRM HTTP requests use a common structure.

The following syntax applies to all services, except as noted.

Requests

GET /{service}/{version}/{profile}/{coordinates}[.{format}]?option=value&option=value
Parameter Description
service One of the following values: route, nearest, table, match, trip, tile
version Version of the protocol implemented by the service. v1 for all OSRM 5.x installations
profile Mode of transportation, is determined statically by the Lua profile that is used to prepare the data using osrm-extract. Typically car, bike or foot if using one of the supplied profiles.
coordinates String of format {longitude},{latitude};{longitude},{latitude}[;{longitude},{latitude} ...] or polyline({polyline}) or polyline6({polyline6}).
format Only json is supported at the moment. This parameter is optional and defaults to json.

Passing any option=value is optional. polyline follows Google's polyline format with precision 5 by default and can be generated using this package.

To pass parameters to each location some options support an array like encoding:

Request options

Option Values Description
bearings {bearing};{bearing}[;{bearing} ...] Limits the search to segments with given bearing in degrees towards true north in clockwise direction.
radiuses {radius};{radius}[;{radius} ...] Limits the search to given radius in meters.
generate_hints true (default), false Adds a Hint to the response which can be used in subsequent requests, see hints parameter.
hints {hint};{hint}[;{hint} ...] Hint from previous request to derive position in street network.
approaches {approach};{approach}[;{approach} ...] Keep waypoints on curb side.
exclude {class}[,{class}] Additive list of classes to avoid, order does not matter.
snapping default (default), any Default snapping avoids is_startpoint (see profile) edges, any will snap to any edge in the graph

Where the elements follow the following format:

Element Values
bearing {value},{range} integer 0 .. 360,integer 0 .. 180
radius double >= 0 or unlimited (default)
hint Base64 string
approach curb or unrestricted (default)
class A class name determined by the profile or none. 
{option}={element};{element}[;{element} ... ]

The number of elements must match exactly the number of locations (except for generate_hints and exclude). If you don't want to pass a value but instead use the default you can pass an empty element.

Example: 2nd location use the default value for option:

{option}={element};;{element}

Example Requests

# Query on Berlin with three coordinates:
curl 'http://router.project-osrm.org/route/v1/driving/13.388860,52.517037;13.397634,52.529407;13.428555,52.523219?overview=false'

Options

In addition to the general options the following options are supported for this service:

Option Values Description
sources {index};{index}[;{index} ...] or all (default) Use location with given index as source.
destinations {index};{index}[;{index} ...] or all (default) Use location with given index as destination.
annotations duration (default), distance, or duration,distance Return the requested table or tables in response.
fallback_speed double > 0 If no route found between a source/destination pair, calculate the as-the-crow-flies distance, then use this speed to estimate duration.
fallback_coordinate input (default), or snapped When using a fallback_speed, use the user-supplied coordinate (input), or the snapped location (snapped) for calculating distances.
scale_factor double > 0 Use in conjunction with annotations=durations. Scales the table duration values by this number.

Unlike other array encoded options, the length of sources and destinations can be smaller or equal to number of input locations;

Example:

Match service

Map matching matches/snaps given GPS points to the road network in the most plausible way. Please note the request might result multiple sub-traces. Large jumps in the timestamps (> 60s) or improbable transitions lead to trace splits if a complete matching could not be found. The algorithm might not be able to match all points. Outliers are removed if they can not be matched successfully.

GET /match/v1/{profile}/{coordinates}?steps={true|false}&geometries={polyline|polyline6|geojson}&overview={simplified|full|false}&annotations={true|false}

In addition to the general options the following options are supported for this service:

Option Values Description
steps true, false (default) Returned route steps for each route
geometries polyline (default), polyline6, geojson Returned route geometry format (influences overview and per step)
annotations true, false (default), nodes, distance, duration, datasources, weight, speed Returns additional metadata for each coordinate along the route geometry.
overview simplified (default), full, false Add overview geometry either full, simplified according to highest zoom level it could be display on, or not at all.
timestamps {timestamp};{timestamp}[;{timestamp} ...] Timestamps for the input locations in seconds since UNIX epoch. Timestamps need to be monotonically increasing.
radiuses {radius};{radius}[;{radius} ...] Standard deviation of GPS precision used for map matching. If applicable use GPS accuracy.
gaps split (default), ignore Allows the input track splitting based on huge timestamp gaps between points.
tidy true, false (default) Allows the input track modification to obtain better matching quality for noisy tracks.
waypoints {index};{index};{index}... Treats input coordinates indicated by given indices as waypoints in returned Match object. Default is to treat all input coordinates as waypoints.
Parameter Values
timestamp integer seconds since UNIX epoch
radius double >= 0 (default 5m)

The radius for each point should be the standard error of the location measured in meters from the true location. Use Location.getAccuracy() on Android or CLLocation.horizontalAccuracy on iOS. This value is used to determine which points should be considered as candidates (larger radius means more candidates) and how likely each candidate is (larger radius means far-away candidates are penalized less). The area to search is chosen such that the correct candidate should be considered 99.9% of the time (for more details see this ticket).

Response

  • code if the request was successful Ok otherwise see the service dependent and general status codes.
  • tracepoints: Array of Waypoint objects representing all points of the trace in order. If the trace point was ommited by map matching because it is an outlier, the entry will be null. Each Waypoint object has the following additional properties:
    • matchings_index: Index to the Route object in matchings the sub-trace was matched to.
    • waypoint_index: Index of the waypoint inside the matched route.
    • alternatives_count: Number of probable alternative matchings for this trace point. A value of zero indicate that this point was matched unambiguously. Split the trace at these points for incremental map matching.
  • matchings: An array of Route objects that assemble the trace. Each Route object has the following additional properties:
    • confidence: Confidence of the matching. float value between 0 and 1. 1 is very confident that the matching is correct.

In case of error the following codes are supported in addition to the general ones:

Type Description
NoMatch No matchings found.

All other properties might be undefined.

Trip service

The trip plugin solves the Traveling Salesman Problem using a greedy heuristic (farthest-insertion algorithm) for 10 or more waypoints and uses brute force for less than 10 waypoints. The returned path does not have to be the fastest path. As TSP is NP-hard it only returns an approximation. Note that all input coordinates have to be connected for the trip service to work.

GET /trip/v1/{profile}/{coordinates}?roundtrip={true|false}&source{any|first}&destination{any|last}&steps={true|false}&geometries={polyline|polyline6|geojson}&overview={simplified|full|false}&annotations={true|false}'

In addition to the general options the following options are supported for this service:

Option Values Description
roundtrip true (default), false Returned route is a roundtrip (route returns to first location)
source any (default), first Returned route starts at any or first coordinate
destination any (default), last Returned route ends at any or last coordinate
steps true, false (default) Returned route instructions for each trip
annotations true, false (default), nodes, distance, duration, datasources, weight, speed Returns additional metadata for each coordinate along the route geometry.
geometries polyline (default), polyline6, geojson Returned route geometry format (influences overview and per step)
overview simplified (default), full, false Add overview geometry either full, simplified according to highest zoom level it could be display on, or not at all.

Fixing Start and End Points

It is possible to explicitely set the start or end coordinate of the trip. When source is set to first, the first coordinate is used as start coordinate of the trip in the output. When destination is set to last, the last coordinate will be used as destination of the trip in the returned output. If you specify any, any of the coordinates can be used as the first or last coordinate in the output.

However, if source=any&destination=any the returned round-trip will still start at the first input coordinate by default.

Currently, not all combinations of roundtrip, source and destination are supported. Right now, the following combinations are possible:

roundtrip source destination supported
true first last yes
true first any yes
true any last yes
true any any yes
false first last yes
false first any no
false any last no
false any any no

  • waypoints: Array of Waypoint objects representing all waypoints in input order. Each Waypoint object has the following additional properties:
    • trips_index: Index to trips of the sub-trip the point was matched to.
    • waypoint_index: Index of the point in the trip.
  • trips: An array of Route objects that assemble the trace.

In case of error the following codes are supported in addition to the general ones:

Type Description

NotImplemented This request is not supported

All other properties might be undefined.

Tile service

This service generates Mapbox Vector Tiles that can be viewed with a vector-tile capable slippy-map viewer. The tiles contain road geometries and metadata that can be used to examine the routing graph. The tiles are generated directly from the data in-memory, so are in sync with actual routing results, and let you examine which roads are actually routable, and what weights they have applied.

GET /tile/v1/{profile}/tile({x},{y},{zoom}).mvt

The x, y, and zoom values are the same as described at https://wiki.openstreetmap.org/wiki/Slippy_map_tilenames, and are supported by vector tile viewers like Mapbox GL JS.

Example request

# This fetches a Z=13 tile for downtown San Francisco:
curl 'http://router.project-osrm.org/tile/v1/car/tile(1310,3166,13).mvt'

Example response

example rendered tile http://map.project-osrm.org/debug/#14.33/52.5212/13.3919

The response object is either a binary encoded blob with a Content-Type of application/x-protobuf, or a 404 error. Note that OSRM is hard-coded to only return tiles from zoom level 12 and higher (to avoid accidentally returning extremely large vector tiles).

Vector tiles contain two layers:

speeds layer:

Property Type Description
speed integer the speed on that road segment, in km/h
is_small boolean whether this segment belongs to a small (< 1000 node) strongly connected component
datasource string the source for the speed value (normally lua profile unless you're using the traffic update feature, in which case it contains the stem of the filename that supplied the speed value for this segment
duration float how long this segment takes to traverse, in seconds. This value is to calculate the total route ETA.
weight integer how long this segment takes to traverse, in units (may differ from duration when artificial biasing is applied in the Lua profiles). ACTUAL ROUTING USES THIS VALUE.
name string the name of the road this segment belongs to
rate float the value of length/weight - analagous to speed, but using the weight value rather than duration, rounded to the nearest integer
is_startpoint boolean whether this segment can be used as a start/endpoint for routes

turns layer:

Property Type Description
bearing_in integer the absolute bearing that approaches the intersection. -180 to +180, 0 = North, 90 = East
turn_angle integer the angle of the turn, relative to the bearing_in. -180 to +180, 0 = straight ahead, 90 = 90-degrees to the right
cost float the time we think it takes to make that turn, in seconds. May be negative, depending on how the data model is constructed (some turns get a "bonus").
weight float the weight we think it takes to make that turn. May be negative, depending on how the data model is constructed (some turns get a "bonus"). ACTUAL ROUTING USES THIS VALUE
type string the type of this turn - values like turn, continue, etc. See the StepManeuver for a partial list, this field also exposes internal turn types that are never returned with an API response
modifier string the direction modifier of the turn (left, sharp left, etc)

Result objects

Route object

Represents a route through (potentially multiple) waypoints.

Properties

  • distance: The distance traveled by the route, in float meters.
  • duration: The estimated travel time, in float number of seconds.

  • weight: The calculated weight of the route.
  • weight_name: The name of the weight profile used during extraction phase.
overview Description
simplified Geometry is simplified according to the highest zoom level it can still be displayed on full.
full Geometry is not simplified.
false Geometry is not added.
  • legs: The legs between the given waypoints, an array of RouteLeg objects.

StepManeuver object

Properties

  • location: A [longitude, latitude] pair describing the location of the turn.
  • bearing_before: The clockwise angle from true north to the direction of travel immediately before the maneuver. Range 0-359.
  • bearing_after: The clockwise angle from true north to the direction of travel immediately after the maneuver. Range 0-359.
  • type A string indicating the type of maneuver. new identifiers might be introduced without API change Types unknown to the client should be handled like the turn type, the existence of correct modifier values is guranteed.
type Description
turn a basic turn into direction of the modifier
new name no turn is taken/possible, but the road name changes. The road can take a turn itself, following modifier.
depart indicates the departure of the leg
arrive indicates the destination of the leg
merge merge onto a street (e.g. getting on the highway from a ramp, the modifier specifies the direction of the merge)
ramp Deprecated. Replaced by on_ramp and off_ramp.
on ramp take a ramp to enter a highway (direction given my modifier)
off ramp take a ramp to exit a highway (direction given my modifier)
fork take the left/right side at a fork depending on modifier
end of road road ends in a T intersection turn in direction of modifier
use lane Deprecated replaced by lanes on all intersection entries
continue Turn in direction of modifier to stay on the same road
roundabout traverse roundabout, if the route leaves the roundabout there will be an additional property exit for exit counting. The modifier specifies the direction of entering the roundabout.
rotary a traffic circle. While very similar to a larger version of a roundabout, it does not necessarily follow roundabout rules for right of way. It can offer rotary_name and/or rotary_pronunciation parameters (located in the RouteStep object) in addition to the exit parameter (located on the StepManeuver object).
roundabout turn Describes a turn at a small roundabout that should be treated as normal turn. The modifier indicates the turn direciton. Example instruction: At the roundabout turn left.
notification not an actual turn but a change in the driving conditions. For example the travel mode or classes. If the road takes a turn itself, the modifier describes the direction
exit roundabout Describes a maneuver exiting a roundabout (usually preceeded by a roundabout instruction)
exit rotary Describes the maneuver exiting a rotary (large named roundabout)

Please note that even though there are new name and notification instructions, the mode and name can change between all instructions. They only offer a fallback in case nothing else is to report.

  • modifier An optional string indicating the direction change of the maneuver.
modifier Description
uturn indicates reversal of direction
sharp right a sharp right turn
right a normal turn to the right
slight right a slight turn to the right
straight no relevant change in direction
slight left a slight turn to the left
left a normal turn to the left
sharp left a sharp turn to the left

The list of turns without a modifier is limited to: depart/arrive. If the source/target location is close enough to the depart/arrive location, no modifier will be given.

The meaning depends on the type property.

type Description
turn modifier indicates the change in direction accomplished through the turn
depart/arrive modifier indicates the position of departure point and arrival point in relation to the current direction of travel
  • exit An optional integer indicating number of the exit to take. The property exists for the roundabout / rotary property: Number of the roundabout exit to take. If exit is undefined the destination is on the roundabout.

New properties (potentially depending on type) may be introduced in the future without an API version change.

Lane object

A Lane represents a turn lane at the corresponding turn location.

Properties

  • indications: a indication (e.g. marking on the road) specifying the turn lane. A road can have multiple indications (e.g. an arrow pointing straight and left). The indications are given in an array, each containing one of the following types. Further indications might be added on without an API version change.
value Description
none No dedicated indication is shown.
uturn An indication signaling the possibility to reverse (i.e. fully bend arrow).
sharp right An indication indicating a sharp right turn (i.e. strongly bend arrow).
right An indication indicating a right turn (i.e. bend arrow).
slight right An indication indicating a slight right turn (i.e. slightly bend arrow).
straight No dedicated indication is shown (i.e. straight arrow).
slight left An indication indicating a slight left turn (i.e. slightly bend arrow).
left An indication indicating a left turn (i.e. bend arrow).
sharp left An indication indicating a sharp left turn (i.e. strongly bend arrow).
  • valid: a boolean flag indicating whether the lane is a valid choice in the current maneuver

Example

{
    "indications": ["left", "straight"],
    "valid": "false"
}

Intersection object

An intersection gives a full representation of any cross-way the path passes bay. For every step, the very first intersection (intersections[0]) corresponds to the location of the StepManeuver. Further intersections are listed for every cross-way until the next turn instruction.

Properties

  • location: A [longitude, latitude] pair describing the location of the turn.
  • bearings: A list of bearing values (e.g. [0,90,180,270]) that are available at the intersection. The bearings describe all available roads at the intersection. Values are between 0-359 (0=true north)
  • classes: An array of strings signifying the classes (as specified in the profile) of the road exiting the intersection.
  • entry: A list of entry flags, corresponding in a 1:1 relationship to the bearings. A value of true indicates that the respective road could be entered on a valid route. false indicates that the turn onto the respective road would violate a restriction.
  • in: index into bearings/entry array. Used to calculate the bearing just before the turn. Namely, the clockwise angle from true north to the direction of travel immediately before the maneuver/passing the intersection. Bearings are given relative to the intersection. To get the bearing in the direction of driving, the bearing has to be rotated by a value of 180. The value is not supplied for depart maneuvers.
  • out: index into the bearings/entry array. Used to extract the bearing just after the turn. Namely, The clockwise angle from true north to the direction of travel immediately after the maneuver/passing the intersection. The value is not supplied for arrive maneuvers.
  • lanes: Array of Lane objects that denote the available turn lanes at the intersection. If no lane information is available for an intersection, the lanes property will not be present.

Example

{
    "location":[13.394718,52.543096],
    "in":0,
    "out":2,
    "bearings":[60,150,240,330],
    "entry":["false","true","true","true"],
    "classes": ["toll", "restricted"],
    "lanes":{
        "indications": ["left", "straight"],
        "valid": "false"
    }
}

Waypoint object

Object used to describe waypoint on a route.

Properties

  • name Name of the street the coordinate snapped to
  • location Array that contains the [longitude, latitude] pair of the snapped coordinate
  • distance The distance, in metres, from the input coordinate to the snapped coordinate
  • hint Unique internal identifier of the segment (ephemeral, not constant over data updates) This can be used on subsequent request to significantly speed up the query and to connect multiple services. E.g. you can use the hint value obtained by the nearest query as hint values for route inputs.
