Re: [sumo-user] Traffic flow disappears after some time
That explains it. 24 hours matches the time when my flow stopped. Thanks so much for the info!

Re: [sumo-user] Arbitrary departure time for vehicles controlled via TraCI
Hi Jacob, >From line 1202 in _vehicle.py, the add() method multiplies the input by 1000, >so it seems that it receives input in seconds.
