The entrance point for this problem is: https://github.com/eclipse-sumo/sumo/blob/eede07d32811e5ad51c8c8847b5955cefe2743b6/src/netimport/NIImporter_OpenStreetMap.cpp#L945-L946 Any OSM node which has a railway tag with a value containing the keyword "crossing" will be treated as a railway crossing....

By setting `traci.vehicle.setSpeedMode(vehicleID,30)`, you have chosen deliberately to allow unsafe following speeds. See the documentation of the [speed mode](https://sumo.dlr.de/docs/TraCI/Change_Vehicle_State.html#speed_mode_0xb3).

Please run your simulation again without setting speed mode at all. If you still encounter collisions, you can attach an archive with your scenario data here for us to check.

@LekYang Do you still have the problem or can we close here? Please provide us with the scenario to reproduce it ourselves in case you still struggle...

Vehicles collide even without any speed mode changes...

I suggest to get the missing files from the Github repository as a workaround. Although traas has been deprecated because a TraCI Java interface is provided by [libtraci](https://sumo.dlr.de/docs/Libtraci.html), the files...

Did you start the (virtual) LISA controller as well (see [docs](https://sumo.dlr.de/docs/Tools/LiSuM.html#lisa_virtual_controller))? This one actually executes the TL logic given inputs from the user (e.g. time, detector occupancy, ...)

Your case is different from the cited [issue](https://github.com/eclipse-sumo/sumo/issues/10933) as you didn't define a taxi fleet at all. Your person is transported by a triggered vehicle (see docs about [PersonTrip](https://sumo.dlr.de/docs/Specification/Persons.html#persontrips)). You...

Sorry I mixed a bit two different things. 1. You didn't define a taxi vehicle at all (only the vehicle type). You just defined trips to be completed with a...
