9 years ago Hi, Rafael! We have actually moved away from using that code and are now doing all of our travel time calculations using OpenTripPlanner. In terms of its GTFS processing, this tool is really quite primitive.
To answer your specific questions:
- The travel time calculator processes a single GTFS file at a time. To process multiple files you’d first need to merge them into a single GTFS file (and a single service ID).
- If no service ID is specified, I believe it defaults to the first service ID listed in calendar.txt, though I’d suggest checking the code to confirm.

Hi Owen.
What would be the best way to proceed if I have three separate GTFS.zip files (one for each mode, including bus, subway and trains) and I would like to compute the travel time matrix considering potential boardings across transport modes. Any idea on this?
On a related topic, what happens if I do not specify -id [service id] ? In a fairly simple simulation I did (symmetrical travel time matrix of 5 points in Portland), I notice the algorithm still works without this input and there was not any difference in the results.csv.
