Transit routing

Transit routing calculates routes using public transportation. When the travel mode is set to Transit, the route is computed using public transit networks including buses, subways, trains, and other transit types. Transit routes include pedestrian legs for walking to and from transit stops.

Supported transit modes

The following transit modes are supported.

Mode	Description
AerialTramway	Aerial tramways and cable cars that transport passengers suspended above ground on overhead cables.
Airplane	Airplane services that are part of the public transit network.
Bus	Standard public bus services operating on fixed routes.
BusRapidTransit	Rapid bus services that operate on dedicated lanes with limited stops, offering faster service than standard buses.
CityTrain	City and commuter trains that operate within urban and suburban areas.
Ferry	Boat and ferry services that are part of the public transit network, transporting passengers across waterways.
FunicularRailway	Inclined railways and funiculars that use cable traction to ascend and descend steep slopes.
HighSpeedTrain	High-speed trains that operate on dedicated tracks at speeds significantly faster than conventional rail.
IntercityTrain	Long-distance trains connecting major cities.
InterregionalTrain	Inter-regional and fast trains that connect areas between cities and regions.
LightRail	Trams and light rail systems that typically operate at street level or on dedicated tracks within urban areas.
Monorail	Monorail systems that operate on a single rail or beam, typically elevated above street level.
PrivateBus	Privately operated bus and taxi services that supplement the public transit network.
RegionalTrain	Regional trains that serve shorter routes within a geographic area, making frequent stops at local stations.
Subway	Underground metro and subway systems that operate on dedicated tracks beneath city streets.

Modes

By default, all transit modes are allowed. You can control which modes are used with either AllowedModes or ExcludedModes:

• AllowedModes – Only the specified modes are used. All other modes are disabled.

• ExcludedModes – The specified modes are disabled. All other modes remain enabled.

You cannot use AllowedModes and ExcludedModes together in the same request.

Unsupported fields

Transit routing supports a different set of request fields compared to other travel modes. The following top-level fields are not supported when the travel mode is set to Transit.

Field	Description
Allow	Road features to allow during route calculation, such as high occupancy lanes.
Avoid	Road features or areas to avoid during route calculation, such as toll roads or ferries.
Driver	Driver-related options such as schedule or rest rules.
Exclude	Exclusion options such as specific countries to avoid.
OptimizeRoutingFor	Optimization objective for routing, such as fastest or shortest distance.
SpanAdditionalFeatures	Additional span-level features such as speed limits or road attributes.
Tolls	Toll cost calculation options.
Traffic	Traffic usage options for route calculation.
TravelStepType	Turn-by-turn step type for route instructions.
Waypoints	Intermediate waypoints along the route.
