This is an example OpenTripPlanner server. It uses data publicly available from SEPTA.
Build the Docker image and run.
docker build . -t septa-otp
docker run -p 8080:8080 septa-otp
Check out the OpenTripPlanner API docs here.
Once you have an instance running locally, you can get a list of stops from:
http://localhost:8080/otp/routers/default/index/stops
Say you are living in Levittown, PA and would like to get to 34th Street Station (the closest train station to Drexel's CCI). You want to leave at 5:00PM on July 1st, 2021. Here, 2:90702 and 1:19026 are the IDs of Levittown and 34th Street Station, respectively.
http://localhost:8080/otp/routers/default/plan?&mode=TRANSIT&fromPlace=2:90702&toPlace=1:19026&date=2021-07-01&time=5:00PM
The most useful part of this response is the list of itineraries. Each itinerary describes how to get from point A to point B. If you want to see all possible itineraries for the whole day, we can start at 12:00AM and look over the next 24 hours (or 86,400 seconds).
http://localhost:8080/otp/routers/default/plan?&mode=TRANSIT&fromPlace=2:90702&toPlace=1:19026&date=2021-07-01&time=12:00AM&searchWindow=86400
Finally, the parameter showIntermediateStops=true will show us all the stops between our source and destination which might be useful in some cases.
