Take a random bus from the realtime data API and get it’s route ID, I got “2446_884”. Great.
Now try and find “2446_884” as a route ID in the GTFS static routes.txt under route_id.
You can’t, it’s under a different format e.g “28-244-sj2-1”
My question is, how do I find the relevant route in routes.txt from the realtime route_id?
Thanks.
Make sure you’re using the correct GTFS timetable data.
GTFS for realtime - This is the GTFS timetable that matches the realtime timetable
“Static timetables, stop locations, and route shape information in GTFS format for operators that support realtime”
GTFS Timetables complete - this is a ‘different’ version of the GTFS timetable that doesn’t match the realtime
“Static timetables, stop locations, and route shape information in General Transit Feed Specification (GTFS) format for all operators, including regional, trackwork and transport routes not available in realtime feeds.”
