overview

RouteStep

Consists of a maneuver such as a turn or merge, followed by a distance of travel along a single way to the subsequent step.

  • distance: The distance of travel from the maneuver to the subsequent step, in float meters.
  • duration: The estimated travel time, in float number of seconds.
  • geometry: The unsimplified geometry of the route segment, depending on the geometries parameter.

  • name: The name of the way along which travel proceeds.

  • pronunciation: The pronunciation hint of the way name. Will be undefined if there is no pronunciation hit.
  • destinations: The destinations of the way. Will be undefined if there are no destinations.
  • mode: A string signifying the mode of transportation.
  • maneuver: A StepManeuver object representing the maneuver.
  • intersections: A list of Intersections that are passed along the segment, the very first belonging to the StepManeuver

Maneuver Type

turn: a basic turn into direction of the modifier

new name: no turn is taken/possible, but the road name changes. The road can take a turn itself, following modifier.

depart: indicates the departure of the leg

arrive: indicates the destination of the leg

merge: merge onto a street

on ramp: take a ramp to enter a highway (direction given my modifier)

off ramp: take a ramp to exit a highway (direction given my modifier)

fork: take the left/right side at a fork depending on modifier

end of road: road ends in a T intersection turn in direction of modifier

continue: Turn in direction of modifier to stay on the same road

roundabout: traverse roundabout, has additional field exit with NR if the roundabout is left

rotary: a larger version of a roundabout, can offer rotary_name in addition to the exit parameter.

roundabout turn: Describes a turn at a small roundabout that should be treated as normal turn. The modifier indicates the turn direciton. Example instruction: At the roundabout turn left.

notification: not an actual turn but a change in the driving conditions. For example the travel mode. If the road takes a turn itself, the modifier describes the direction

Maneuver Modifier

uturn: indicates reversal of direction

sharp right: a sharp right turn

right: a normal turn to the right

slight right: a slight turn to the right

straight: no relevant change in direction

slight left: a slight turn to the left

left: a normal turn to the left

sharp left: a sharp turn to the left

Intersections

  • location: A [longitude, latitude] pair describing the location of the turn.
  • bearings: A list of bearing values (e.g. [0,90,180,270]) that are available at the intersection. The bearings describe all available roads at the intersection.
  • entry: A list of entry flags, corresponding in a 1:1 relationship to the bearings. A value of true indicates that the respective road could be entered on a valid route. false indicates that the turn onto the respective road would violate a restriction.
  • in: index into bearings/entry array. Used to calculate the bearing just before the turn. Namely, the clockwise angle from true north to the direction of travel immediately before the maneuver/passing the intersection. Bearings are given relative to the intersection. To get the bearing in the direction of driving, the bearing has to be rotated by a value of 180. The value is not supplied for depart maneuvers.
  • out: index into the bearings/entry array. Used to extract the bearing just after the turn. Namely, The clockwise angle from true north to the direction of travel immediately after the maneuver/passing the intersection. The value is not supplied for arrive maneuvers.
