Google and TriMet have set a groundbreaking standard in transit trip planning by harnessing the power of open datasets with the GTFS (General Transit Feed Specification) and GTFS-RT (Real-Time) standards.1 These specifications are invaluable in conveying essential public transit details such as schedules, routes, stops, and updates to the public.
What is GTFS?
GTFS data is split into static and dynamic segments. Static data encapsulates crucial information about the transportation network, including stops, routes, schedules, and fares. On the other hand, dynamic data, or GTFS-RT, offers real-time updates on transit services such as delays, cancellations, and occupancy rates.
For example, at a bus stop, static data provides details like the stop's name, number, and the associated routes along with their schedules. Dynamic data, or GTFS-RT, updates users about real-time changes like early or late bus arrivals, route modifications, or service alerts. Static data also details operational days, including exceptions for holidays, and offers insights into stop accessibility and specific boarding or alighting points. GTFS additionally supports the dissemination of fare information and precise route mapping.
This framework enables passenger information systems to seamlessly sync with both static and dynamic data, processing millions of changes daily. Updates are smoothly integrated in real time, often refreshed every second, to ensure transparency for users.
How Does GTFS Realtime Work?
GTFS Realtime operates by continuously collecting data regarding the current status of transit services from a multitude of sources. This real-time data is then formatted into a standardized feed that developers and transit agencies can access, enabling them to provide up-to-the-minute information about transit conditions.
Why Use GTFS?
Employed by over 10,000 transit agencies across more than 100 countries2, GTFS stands apart from other data formats due to its design specifically tailored for effective communication of public transportation information3. Managed by a nonprofit, GTFS standards ensure data consistency and reliability, crucial for real-time service updates. This format proves especially useful in corporate settings, where it helps businesses display nearby public transit options on digital screens, enhancing commute options for employees.
The Impact of Real-Time Data
Real-time data profoundly improves public transportation, allowing users to plan their routes with the most current information about schedules and vehicle availability. This data includes updates on location, speed, and the status of transit vehicles, refreshed every few seconds or minutes, depending on the service frequency.
