Track Your Transit is a comprehensive web application designed to provide real-time bus tracking and next vehicle predictions. It caters to a growing list of transit agencies, including many of the largest systems in North America. This means that users can rely on the app to get accurate and timely information about their public transportation options, making their commutes more efficient and less stressful.

The application originally started as SEPTA Selector, focusing on the Southeastern Pennsylvania Transportation Authority (SEPTA). Over time, it expanded its scope to include other transit systems and rebranded as The Selector. The app offers two distinct types of trackers: one for general transit, such as buses, and another specifically for rail systems, including services like Amtrak. This dual functionality makes it versatile and useful for a wide range of users, from daily commuters to long-distance travelers.

Track Your Transit was developed with the transit enthusiasts in mind, but it also provides valuable features for everyday riders. The app offers real-time predictions, showing when the next vehicle is expected to arrive, and displays the current locations of vehicles on a map. This helps users plan their trips more effectively and reduces the uncertainty often associated with public transportation.

To gather the necessary information, Track Your Transit utilizes various data feeds and APIs. It primarily relies on General Transit Feed Specification (GTFS) and GTFS-Realtime (GTFS-RT) feeds, which are standard formats for public transportation schedules and real-time updates. Additionally, the app integrates with other APIs, such as Bustime and Infopoint, to collect comprehensive and up-to-date information. This combination of data sources ensures that users receive the most accurate and reliable transit information available.

Overall, Track Your Transit is a powerful tool for anyone who relies on public transportation, offering a seamless and user-friendly experience to keep riders informed and on schedule.
