RouteOptions
A RouteOptions
object is a structure that specifies the criteria for results returned by the Mapbox Directions API.
Pass an instance of this class into the Directions.calculate(_:completionHandler:)
method.
-
Initializes a route options object for routes between the given waypoints and an optional profile identifier.
-
Initializes a route options object for routes between the given locations and an optional profile identifier.
Note
This initializer is intended for
CLLocation
objects created using theCLLocation.init(latitude:longitude:)
initializer. If you intend to use aCLLocation
object obtained from aCLLocationManager
object, consider increasing thehorizontalAccuracy
or set it to a negative value to avoid overfitting, since theWaypoint
class’scoordinateAccuracy
property represents the maximum allowed deviation from the waypoint. -
Initializes a route options object for routes between the given geographic coordinates and an optional profile identifier.
-
-
-
Initializes an equivalent route options object from a match options object. Desirable for building a navigation experience from map matching.
-
A Boolean value that indicates whether a returned route may require a point U-turn at an intermediate waypoint.
If the value of this property is
true
, a returned route may require an immediate U-turn at an intermediate waypoint. At an intermediate waypoint, if the value of this property isfalse
, each returned route may continue straight ahead or turn to either side but may not U-turn. This property has no effect if only two waypoints are specified.Set this property to
true
if you expect the user to traverse each leg of the trip separately. For example, it would be quite easy for the user to effectively “U-turn” at a waypoint if the user first parks the car and patronizes a restaurant there before embarking on the next leg of the trip. Set this property tofalse
if you expect the user to proceed to the next waypoint immediately upon arrival. For example, if the user only needs to drop off a passenger or package at the waypoint before continuing, it would be inconvenient to perform a U-turn at that location.The default value of this property is
false
when the profile identifier isProfileIdentifier.automobile
orProfileIdentifier.automobileAvoidingTraffic
andtrue
otherwise. -
The route classes that the calculated routes will avoid.
Currently, you can only specify a single road class to avoid.
-
The route classes that the calculated routes will allow.
This property has no effect unless the profile identifier is set to
ProfileIdentifier.automobile
orProfileIdentifier.automobileAvoidingTraffic
. -
The number that influences whether the route should prefer or avoid alleys or narrow service roads between buildings. If this property isn’t explicitly set, the Directions API will choose the most reasonable value.
This property has no effect unless the profile identifier is set to
ProfileIdentifier.automobile
orProfileIdentifier.walking
.The value of this property must be at least
DirectionsPriority.low
and at mostDirectionsPriority.high
.DirectionsPriority.medium
neither prefers nor avoids alleys, while a negative value betweenDirectionsPriority.low
andDirectionsPriority.medium
avoids alleys, and a positive value betweenDirectionsPriority.medium
andDirectionsPriority.high
prefers alleys. A value of 0.9 is suitable for pedestrians who are comfortable with walking down alleys. -
The number that influences whether the route should prefer or avoid roads or paths that are set aside for pedestrian-only use (walkways or footpaths). If this property isn’t explicitly set, the Directions API will choose the most reasonable value.
This property has no effect unless the profile identifier is set to
ProfileIdentifier.walking
. You can adjust this property to avoid sidewalks and crosswalks that are mapped as separate footpaths, which may be more granular than needed for some forms of pedestrian navigation.The value of this property must be at least
DirectionsPriority.low
and at mostDirectionsPriority.high
.DirectionsPriority.medium
neither prefers nor avoids walkways, while a negative value betweenDirectionsPriority.low
andDirectionsPriority.medium
avoids walkways, and a positive value betweenDirectionsPriority.medium
andDirectionsPriority.high
prefers walkways. A value of −0.1 results in less verbose routes in cities where sidewalks and crosswalks are generally mapped as separate footpaths. -
The expected uniform travel speed measured in meters per second. If this property isn’t explicitly set, the Directions API will choose the most reasonable value.
This property has no effect unless the profile identifier is set to
ProfileIdentifier.walking
. You can adjust this property to account for running or for faster or slower gaits. When the profile identifier is set to another profile identifier, such asProfileIdentifier.driving
, this property is ignored in favor of the expected travel speed on each road along the route. This property may be supported by other routing profiles in the future.The value of this property must be at least
CLLocationSpeed.minimumWalking
and at mostCLLocationSpeed.maximumWalking
.CLLocationSpeed.normalWalking
corresponds to a typical preferred walking speed. -
The desired arrival time, ignoring seconds precision, in the local time at the route destination.
This property has no effect unless the profile identifier is set to
ProfileIdentifier.automobile
. -
The desired departure time, ignoring seconds precision, in the local time at the route origin
This property has no effect unless the profile identifier is set to
ProfileIdentifier.automobile
orProfileIdentifier.automobileAvoidingTraffic
.
-
A Boolean value indicating whether alternative routes should be included in the response.
If the value of this property is
false
, the server only calculates a single route that visits each of the waypoints. If the value of this property istrue
, the server attempts to find additional reasonable routes that visit the waypoints. Regardless, multiple routes are only returned if it is possible to visit the waypoints by a different route without significantly increasing the distance or travel time. The alternative routes may partially overlap with the preferred route, especially if intermediate waypoints are specified.Alternative routes may take longer to calculate and make the response significantly larger, so only request alternative routes if you intend to display them to the user or let the user choose them over the preferred route. For example, do not request alternative routes if you only want to know the distance or estimated travel time to a destination.
The default value of this property is
false
. -
A Boolean value indicating whether the route includes a
ManeuverType.exitRoundabout
orManeuverType.exitRotary
step when traversing a roundabout or rotary, respectively.If this option is set to
true
, a route that traverses a roundabout includes both aManeuverType.takeRoundabout
step and aManeuverType.exitRoundabout
step; likewise, a route that traverses a large, named roundabout includes both aManeuverType.takeRotary
step and aManeuverType.exitRotary
step. Otherwise, it only includes aManeuverType.takeRoundabout
orManeuverType.takeRotary
step. This option is set tofalse
by default. -
A Boolean value indicating whether
Directions
can refresh time-dependent properties of theRouteLeg
s of the resultingRoute
s.To refresh the
RouteLeg.expectedSegmentTravelTimes
,RouteLeg.segmentSpeeds
, andRouteLeg.segmentCongestionLevels
properties, use theDirections.refreshRoute(responseIdentifier:routeIndex:fromLegAtIndex:completionHandler:)
method. This property is ignored unlessprofileIdentifier
isProfileIdentifier.automobileAvoidingTraffic
. This option is set tofalse
by default. -
The maximum vehicle height.
If this parameter is provided,
Directions
will compute a route that includes only roads with a height limit greater than or equal to the max vehicle height or no height limit. This property is supported byDirectionsProfileIdentifier.automobile
andDirectionsProfileIdentifier.automobileAvoidingTraffic
profiles. The value must be between 0 and 10 when converted to meters. -
The maximum vehicle width.
If this parameter is provided,
Directions
will compute a route that includes only roads with a width limit greater than or equal to the max vehicle width or no width limit. This property is supported byDirectionsProfileIdentifier.automobile
andDirectionsProfileIdentifier.automobileAvoidingTraffic
profiles. The value must be between 0 and 10 when converted to meters. -
The maximum vehicle weight.
If this parameter is provided, the
Directions
will compute a route that includes only roads with a weight limit greater than or equal to the max vehicle weight. This property is supported byDirectionsProfileIdentifier.automobile
andDirectionsProfileIdentifier.automobileAvoidingTraffic
profiles. The value must be between 0 and 100 metric tons. If unspecified, 2.5 metric tons is assumed. -
A radius around the starting point in which the API will avoid returning any significant maneuvers.
Use this option when the vehicle is traveling at a significant speed to avoid dangerous maneuvers when re-routing. If a route is not found using the specified value, it will be ignored. Note that if a large radius is used, the API may ignore an important turn and return a long straight path before the first maneuver.
This value is clamped to
LocationDistance.minimumManeuverIgnoringRadius
andLocationDistance.maximumManeuverIgnoringRadius
.
