OpenRouteService ( - short ORS) - Is much more than a website with a route service for cars, pedestrians and bicycles based on Open Standards and Open Geodata. Several Location Based Services (LBS) created from OSM data are available, developed by Pascal Neis. For example (Neis 2008):
  • Route Service
  • Geocoder/Reverse Geocoder
  • Directory Service
  • Accessibility Analysis Service
  • Emergency Route Service

What can you do on ORS? is much more than only a routing service: it uses a wide range of services based on OSM data that also could be used in other applications and scenarios. Currently the following services have been implemented within the frame of based on OSM data:

ORS Directory Service
  • The Directory Service is a service that provides access to an online directory to find the location of a specific or nearest place, product or service.
  • The Location Utility Service provides a Geocoder/Reverse Geocoder; the Geocoder transforms a description of a location, such as a place name, street address or postal code, into a normalized description of the location with a Point geometry.
ORS Route Service
  • The Route Service determines travel routes and navigation information according to diverse criteria. This has been realized for:
    • cars: fastest, shortest, recommended
    • several options to avoid tools, tunnels, etc.
    • same for heavy vehicles with many options
    • wheelchair routing (beta)
    • cars: use of realtime traffic (TMC), for GERMANY
    • bicycles (MTB, race bike, safest route...)
    • pedestrian
    • further extensions (particular options for different types of bicycles etc.) are planned or in work
ORS Accessibility Analysis Service
  • The Accessibility Analysis Service (AAS) calculates a polygon representing the area that is reachable within a certain time distance based on a street network around a given location.
ORS Emergency Route Service
  • In the Emergency Route Service you can specify areas that will be avoided by your route.

OSM Tags used for Wheelchair Routing

The wheelchair routing profile uses a mixture of static filtering, dynamic filtering and prioritisation.

  • Static Filtering means that OSM features having the listed tags are taken in or out of the routing graph independent of which preferences the users of the profile specify
  • Dynamic Filtering means that the OSM features having the listed tags are taken in or out of the routing graph dependent on which preferences the of the profile specify (such as, incline, surface/smoothness, height of dropped kerbs)
  • Prioritasation means that some OSM features having certain listed tags are getting higher (or lower) priority in route planning over other features, which may result in little detours in favour of a more suitable route

OSM Tags used for Static Filtering of Ways/Nodes Independent on User Preferences

The following table shows a list of tags that are used for static filtering. Depending on whether they are "accepted" or "non accepted", they are part of the graph or are completely taken out of the graph, independent on any user setting, and will NOT be available for any route computation. If they are "accepted" they will be available for any route computation.

Key Values for Accepted Ways Values for Non Accepted Ways
highway "footway", "pedestrian", "living_street", "residential", "unclassified", "service",

"trunk", "trunk_link", "primary", "primary_link", "secondary", "secondary_link", "tertiary", "tertiary_link", "road"

OSM Tags applied for Dynamic Filtering of Way/Nodes Depending On User Preferences

The following features are accepted/not accpeted depending on the preferences the users set in the User Interface of OpenRouteService.


For the keys surface and smoothness following logic applies for sidewalks:

If sidewalk=left|both|right exists, evaluate whether also "sidewalk:surface:left", "sidewalk:surface:both", "sidewalk:surface:right", "sidewalk:smoothness:left", "sidewalk:smoothness:both", "sidewalk:smoothness:right" exist. If so use these values for surface and smoothness of the sidewalks, if not fall back to surface and smoothness of the way, even for the sidewalks

Key route option "concret, asphalt" route option "flattened cobblestone and better" route option "cobblestone and better" route option "compacted" all traversable surfaces

(also: sidewalk:left|both|right:surface)

incline incline <= 0.03 incline <= 0.06 incline <= 0.09 incline <= 0.12 incline <= 0.31

(note: due to a restriction of attribute storage all incline values > 0.31 are mapped to 0.31)

The values "up", "down" and "yes" are mapped to incline = 0.1

The value "steep" is mapped to incline = 0.15

The value "no" is mapped to incline = 0

The values "at_grade", "flush", "flush;lowered" and "flush_and_lowered" are mapped to kerb:height = 0.0

The values "yes", "both", "low", "lowered", "dropped", "rolled", "sloped" and "lowered_and_sloped" are mappend to kerb:height = 0.03

The values "no", "one", "raised", "none" and "regular" are mapped to kerb:height = 0.15

kerb:height kerb:height <= 0.03 kerb:height <= 0.06 kerb:height <= 0.10 kerb:height <= 0.15

The values "no", "one", "raised", "none" and "regular" are mapped to kerb:height = 0.15

OSM Tags used for Prioritisation/Weighting of Features Indpendent of User Preferences

Ways (and also some nodes) get higher weights (positive prioritisation) as well as lower weights (negative prioritisation) depending on their tags. Also combinations of positive and negative features are possible. Segments that have higher weights are more probably to be used in the wheelchair routing.

Key Positive Prioritisation Negative Prioritisation
tunnel "yes"
sidewalk "yes", "both", "right", "left"
foot "designated", "yes", "official", "permissive", "limited"
bicycle "official"
highway "footway", "pedestrian", "living_street", "crossing" "path", "track" (if no further information about surface|smoothness|incline|tracktype is available)

"trunk", "trunk_link", "primary", "primary_link", "secondary", "secondary_link", "tertiary", "tertiary_link", "road (if no sidewalk is tagged)

maxspeed if maxspeed > "50"
footway "crossing"

User Manual Help



  • The OpenRouteService doesn't interpret OSM Relation:restrictions, which can be a severe limit to the usefulness for traffic routing in some cities. This route is incorrect for example, because the a turn restriction relation is in place shown on this map.
  • Clicking the map often leads to an unintentional change in the start or end location marker.
  • Barriers are not taken into credit. Try a route between the two towns Bremm and Dohr. OpenRouteservice would give you the former road which is still accessible but with a barrier that you can't pass with the car. YourNavigation takes the mapped barrier into credit and takes the far longer road (which is the shortest road for cars for about 5 years now) if you choose car navigation. Can somebody please add the recognition of barriers into OpenRouteService.
  • Ways tagged with construction=* or proposed=* are not taken into credit. See for example [8]. This is bad if the map is not up to date. Possible solution: additional permanent RouteLink which enables it. These tags are deprecated.
  • Another example which does not route the shortest way: [9]
  • Example where pedestian routing works well: [10], but the designated cycleway is ignored [11] when routing for bicycles.
