Transit Coverage Types
Intermodal Routing API offers two different levels of coverage for public transit: real-time (with limited geographic coverage) and timetable.
Real-time information ensures that the service considers the vehicle's current location or any sudden service disruptions, to provide an up to date Expected Time of Arrival (ETA) for the Transit services at a particular station. In the context of routing, real-time information is considered within the route and journey calculation process. However, the vehicle's current location messages alone cannot provide enough information to the user; this information needs to be matched with relevant journey information to be useful.
The Park and Ride service sources detailed transit schedules from transit agencies. This information may come in the form of actual times, such as: the train leaves the station at 09:18, or scheduled frequencies, such as: the bus runs every 20 minutes between the hours of 08:00 and 10:40 AM. In addition, timetable transit coverage areas provide a more complete representation of the public transit networks available in a given city or metropolitan area.
