coordinatesThe waypoint's geographic coordinates.typeDefines how a waypoint should be considered for route calculation. The default waypoint type is WaypointType.stopover.transitRadiusInMetersThe maximum allowed distance from the waypoint that the calculated route may pass through. For example, to drive past a city without necessarily going into the city center, you can specify the coordinates of the center and a transit radius of 5000m. The default transit radius is zero. If the route should pass the waypoint as close as possible, the default value should be kept. Note that the waypoint will be map-matched to a road. Non-zero values allow a greater tolerance. Note that Waypoint.sideOfStreetHint option is ignored if the user sets this option with a value greater than zero.headingInDegreesOptional heading angle referenced by true North, clockwise specifying the direction of travel. The heading direction may help the routing algorithm to select the best direction, for example, when multiple directions are possible at a road junction. North is 0 degrees, East is 90 degrees, South is 180 degrees, and West is 270 degrees. The value must be in the range [0, 360] when specified. By default, or whennullis set, heading is ignored for route calculation.sideOfStreetHintOptional coordinates to indicate which side of the street should be used to reach the waypoint. For example, if the location is to the left of the street, the router will prefer using that side in case the street has dividers. Note that this option is ignored if the user sets Waypoint.transitRadiusInMeters option with a value greater than zero.displayLocationOptional coordinates to indicate physical location of the Points of Interest (PoI). It is different from coordinates and Waypoint.sideOfStreetHint which are generally expected to to be on the navigable road network and can be different from actual location of the PoI. display_location is used for visualization of the PoI regardless of road network.minCourseDistanceInMetersOptional distance in meters during which the user wants to avoid taking actions. For example, if the origin is set by a moving vehicle, the user might not have time to react to immediate actions such as a sharp right turn.nameHintOptional name hint causes the router to look for the place with the most similar name. This can e.g. include things like:Northbeing used to differentiate between interstatesI66 NorthandI66 South,Downtown Avenuebeing used to correctly select a residential street.matchSideOfStreetSpecifies how the location set by Waypoint.sideOfStreetHint should be handled. Note that this setting might affect the geometry of the resulting route.durationThe duration in seconds that should be spent at a waypoint of type WaypointType.stopover. Impacts time-aware calculations. Ignored for waypoints of type WaypointType.passThrough. The default duration is 0 seconds.segmentHintOptional segment hint causes the router to try and match to the specified segment. Waypoint coordinates need to be on the segment, otherwise waypoint will be matched ignoring the segment hint. This parameter can be used when the waypoint is too close to more than one segment to force matching to a specific one. Only topology segment id and travel direction are used to define the segment hint
Note:
The feature is not supported by the OfflineRoutingEngine.
onRoadThresholdInMetersOptional threshold allows specifying a distance within which the waypoint could be considered as being on a highway/bridge/tunnel/sliproad. Within this threshold, the attributes of the segments do not impact the matching. Outside the threshold only segments which aren't one of highway/bridge/tunnel/sliproad can be matched.chargingStopSpecifies of a user-planned charging stop. The resultingRoutemay contain this waypoint as aRoutePlacewith a non-nullChargingStationmember when the provided specifications indicate that a stop is required to charge the EV battery. Note: IfEVCarOptions.ensure_reachabilityis not set astrueandChargingStop.min_durationis not provided, route calculation may suggest a better charging stop instead of this stop.currentWeightChangeInKilogramsChanges the value ofvehicle[currentWeight]by this value. Enables the support of scenarios where the vehicle takes additional cargo or unloads its cargo along the route. Changes to the configuration of the vehicle, such as adding a trailer, aren't supported. Relative value in kilograms. Available range: from -40000 to 40000 (inclusive). Note:
- A route request with this parameter requires to set VehicleSpecification.currentWeightInKilograms and VehicleSpecification.grossWeightInKilograms.
- This feature is supported in transport modes of TransportMode.car, TransportMode.taxi, or TransportMode.truck.
Note: This is a beta release of this feature, so there could be a few bugs and unexpected behaviors. Related APIs may change for new releases without a deprecation process.
