Declaration
Swift

public enum Constants
inDrivingDirection
The number of lanes on the road in the driving direction or nil if the number of lanes is not known. If available, the value is in the range Constants.numberOfLanesRange. A value of 0 indicates that the vehicle is moving in the wrong direction on a one-way road. A value equal to the Constants.numberOfLanesRange.upperBound indicates that the actual number of lanes is greater than or equal to the Constants.numberOfLanesRange.upperBound. The value comprises both normal and exit lanes. NumberOfLanes.inDrivingDirection and NumberOfLanes.inOppositeDirection can both be nil at the same time.
Declaration
Swift

public let inDrivingDirection: Int?
inOppositeDirection
The number of lanes on the road in the opposite direction or nil if the number of lanes is not known. If available, the value is in the range NumberOfLanes.Constants.numberOfLanesRange. A value of 0 indicates that the vehicle is moving on a one-way road. A value equal to the Constants.numberOfLanesRange.upperBound indicates that the actual number of lanes is greater than or equal to the Constants.numberOfLanesRange.upperBound. The value comprises both normal and exit lanes. NumberOfLanes.inDrivingDirection and NumberOfLanes.inOppositeDirection can both be nil at the same time.
