ors.engine.profiles
The profiles object contains key-object-pairs for each profile you are using.
There are some default profile keys in our standard ors-config.yml with flag encoders and recommended profile-specific settings predefined. These standard profiles are:
* in ors.engine.profiles.* | flag encoder ors.engine.profiles.*.profile |
|---|---|
car | driving-car |
hgv | driving-hgv |
bike-regular | cycling-regular |
bike-mountain | cycling-mountain |
bike-road | cycling-road |
bike-electric | cycling-electric |
walking | foot-car |
hiking | foot-hgv |
wheelchair | wheelchair |
public-transport | public-transport |
WARNING
The predefined settings override settings specified in the profile_default in your ors-config.yml or ors-config.env!
If you want to specify your own profile settings based on your specific profile_default values, you can work around this by naming your profile differently, e.g. custom-car instead of car. Note that the profile name can be chosen freely but cannot contain special characters that cannot be used for directory names on your operating system.
WARNING
In the directions endpoint, the profiles are addressed by their encoder name (e.g. driving-car)!
Properties for each (enabled) profile are set under ors.engine.profiles.<profile>, e.g.
ors.engine.profiles.carors.engine.profiles.hiking
| key | type | description | default value |
|---|---|---|---|
| profile | string | Profile name for the directions endpoint. Also used as specification for the flag encoder during graph building. Possible values are restricted to those in the second column in above table! | NA |
| enabled | boolean | Enables or disables the profile across openrouteservice endpoints | true |
| elevation | boolean | Specifies whether to use or not elevation data | false |
| elevation_smoothing | boolean | Smooth out elevation data | false |
| traffic | boolean | Use traffic data if available | false |
| interpolate_bridges_and_tunnels | boolean | Toggle elevation interpolation of bridges and tunnels on and off | true |
| instructions | boolean | Specifies whether way names will be stored during the import or not | true |
| optimize | boolean | Optimize the sort order when contracting nodes for CH. This is rather expensive, but yields a better contraction hierarchy. | false |
| graph_path | string | Subdirectory name under ors.engine.graphs_root_path. If left unset, the profile entry name on the profiles list is used | NA |
| encoder_options | string | For details see encoder_options below | |
| preparation | object | Preparation settings for building the routing graphs | |
| execution | object | Execution settings relevant when querying services | |
| ext_storages | object | External storages for returning extra information | |
| maximum_distance | number | The maximum allowed total distance of a route | 100000 |
| maximum_distance_dynamic_weights | number | The maximum allowed distance between two way points when dynamic weights are used | 100000 |
| maximum_distance_avoid_areas | number | The maximum allowed distance between two way points when areas to be avoided are provided | 100000 |
| maximum_distance_alternative_routes | number | The maximum allowed total distance of a route for the alternative routes algorithm | 100000 |
| maximum_distance_round_trip_routes | number | The maximum allowed total distance of a route for the round trip algorithm | 100000 |
| maximum_speed_lower_bound | number | Specifies the threshold for the query parameter maximum_speed | 80 |

| maximum_snapping_radius | number | Maximum distance around a given coordinate to find connectable edges | 400 |
| maximum_visited_nodes | number | Maximum allowed number of visited nodes in shortest path computation | 1000000 |
| encoder_flags_size | number | The number of bytes used for FlagEncoders | 8 |
| location_index_resolution | number | The minimum resolution in meters of tiles in the location index. Lower values yield faster queries at a cost of increased memory requirements. Reducing the resolution reduces the lookup radius which can be compensated by increasing location_index_search_iterations. Corresponds to GraphHopper's index.high_resolution configuration parameter. | 500 |
| location_index_search_iterations | number | The maximum number of iterations performed in coordinates lookup. Higher values yield a broader search area, but might reduce query performance. It only affects the storage lookup but not its layout so changing this parameter does not require rebuilding the location index. Corresponds to GraphHopper's index.max_region_search configuration parameter. | 4 |
| force_turn_costs | boolean | Should turn restrictions be obeyed | false |
| gtfs_file | string | Only for pt profile: location of GTFS data; can either be a zip-file or the unzipped folder | NA |
encoder_options
Properties beneath ors.engine.profiles.*.encoder_options:
| key | type | profiles | description | example value |
|---|---|---|---|---|
| block_fords | boolean | * | Do not route through fords | true |
| consider_elevation | boolean | bike-* | The maximum possible speed is the bike-type specific maximum downhill speed, which is higher than the usual maximum speed | true |
| maximum_grade_level | number | car, hgv | Relates to the quality of tracks as described in tracktype. Specifying e.g. maximum_grade_level=1 means that tracktype=grade2 and below won't be considered for routing. Setting maximum_grade_level=0 discards all tracks with a valid tracktype tag, while a negative value such as maximum_grade_level=-1 entirely disables routing on tracks. | 3 |
| preferred_speed_factor | number | wheelchair | Travel speeds on edges classified as preferable for wheelchair users are multiplied by this factor, use to set faster traveling speeds on such ways | 1.2 |

| turn_costs | boolean | car, hgv, bike-* | Should turn restrictions be respected | true |
| use_acceleration | boolean | car, hgv | Models how a vehicle would accelerate on the road segment to the maximum allowed speed. In practice it reduces speed on shorter road segments such as ones between nearby intersections in a city | true |

ext_storages
For each profile it can be defined which external storages for extra info should be included in the graph. This makes those information available as extra_info in a routing response.
To do so, add a key from the list below. Leave its value empty, unless you want to specify further options (currently only available for RoadAccessRestrictions, Borders and Wheelchair).
Properties beneath ors.engine.profiles.*.ext_storages:
| key | type | description | example value |
|---|---|---|---|
| WayCategory | object | Returns the way category in the route response, Compatible for any profile type | |
| WaySurfaceType | object | Returns the way surface in the route response, Compatible for any profile type | |
| HillIndex | object | Returns the ascent/descent in the route response, Compatible for any profile type | |
| TrailDifficulty | object | Returns the trail difficulty in the route response, Compatible for profile-hiking | |
