For now, trRouting is used exclusively with [transition](https://github.com/chairemobilite/transition)

It may be possible in the future to import GTFS data directly into trRouting, but this is not yet ready.

This is rather complicatd because after a transfer, trRouting doesn't know how it reached the stop, and the path to reach the stop can change afterward, so we cannot look...

Idea: when reaching the last connection of a trip 1 that has the same block_id as a trip 2, we could simply activate trip 2 first connection.

Yes, i approve!
