Transit Arrival Board

A hobby project that uses the MTA's GTFS static and realtime feeds to get realtime transit info about public transit near our high school, The Bronx High School of Science.

Environment Variables

Create a .env file and add the following variables.

MTABUSKEY

The MTA's BusTime feeds require an API key, which you can obtain here.

Configuration

The configuration file is located in config.ts. It is currently set to stops located near The Bronx High School of Science, but this file is meant to be edited to display any stop in the MTA network. Stops can be added (either subway or bus) with StopConfig objects, which is explained in depth below.

stop_ids

Although each GTFS stop_id refers to a single platform, we have anticipated for the need to combine platforms with built-in transfers. The first stop_id is used to distinguish the stop_name and as a key.

walk_time

Although the Rust backend uses the MTA's GTFS realtime feeds to get information about when a vehicle is scheduled to arrive at a station, it may be unhelpful for the vehicle to arrive faster than someone would be able to "catch" it. walk_time is used to remove vehicles from the React.js frontend that are deemed to be unlikely for someone to "catch" it.
