Types of coverage - Public Transit API v8
Public Transit API v8 offers three different levels of coverage:
Real-Time
Real-time information enables the consideration of current vehicle locations or
sudden service disruptions to provide the most up-to-date expected arrival time
of transit services at a specific station. In the context of routing, real-time
information is considered within the route and journey calculation process.
Timetable
Public Transit sources detailed transit schedules from transit agencies. These
schedules may come in the form of actual times (for example, a train leaves a
station at 09:18) or scheduled frequencies (for example, the bus runs every 20
minutes between the hours of 08:00 and 10:40 AM). In addition, timetable transit
coverage areas are a more complete representation of the public transit networks
available in a given city or metropolitan area.
Estimated
With this level of support, the Public Transit provides our best forecast of travel
time based on the transit network configuration, stop density, vehicle type, and
the hours of operation of a given transit system when actual, granular transit
schedule information is not available. It should also be noted that there are
cases where these coverage areas are only partially complete and may not include
all of the public transit options that serve a city. This may include cases where
the HERE Transit Routes service supports one or more, but not all, bus routes,
for example.
