Alternatively, web application servers could also be used which as a response to a valid HTTP GET request will return the feed. The file itself is a regular binary file, so any type of webserver can host and serve the file (other transfer protocols might be used as well). Feeds are served via HTTP and updated frequently. Vehicle positions - information about the vehicles including location and congestion levelĪ feed may, although not required to, combine entities of different types.Service alerts - stop moved, unforeseen events affecting a station, route or the entire network.Trip updates - delays, cancellations, changed routes.The specification currently supports the following types of information: Create your own feeds using the reference.Decide which feed entities you will be providing.The system immediately processes feed updates as Live Transit Updates information. Your feed needs to be available on a location where we can fetch it periodically. We created the GTFS realtime feed format to complement the widely-used GTFS format for static transit schedules. Transit partners provide these updates in their feeds. Live Transit Updates provide two types of real-time updates to users: live departure times and service alerts. These updates include live departure and arrival times to transit stations and service alerts. Live Transit Updates is a service providing real-time transit updates to users of Google Maps and Google Maps for mobile. What is Live Transit Updates for Google Maps? The specification is published under the Apache 2.0 License.
The specification was designed through a partnership of the initial Live Transit Updates partner agencies, a number of transit developers and Google. GTFS Realtime was designed around ease of implementation, good GTFS interoperability and a focus on passenger information. It is an extension to GTFS (General Transit Feed Specification), an open data format for public transportation schedules and associated geographic information. GTFS Realtime is a feed specification that allows public transportation agencies to provide realtime updates about their fleet to application developers. As a result, in case of an unfortunate delay, a rider would be relieved to know that they can stay home a little bit longer.
Providing up-to-date information about current arrival and departure times allows users to smoothly plan their trips. Providing users transit data updates in real time greatly enhances their experience of your transit services. GTFS Realtime Best Practices on the Mobility Data site.
