I want to keep a constant number of cars in my (long) simulation (OMNeT+Veins). I do not care about mobility that much so i could probably use the Veins in-built function *.manager.numVehicles = 100. The thing is that if i do not specify any(enough) vehicle flows (from SUMO) my simulation terminates instantly (because of no events). So i create some flows (that exit the simulation sooner) and Veins fills up for the cars as they dissappear.

Is there a more elegant way to do this? I'd prefer to just use the numVehicles function since it's easier and the cars move minimally so they remain in the simulation for long.

I need steady-state vehicular density (number of vehicles fixed - even if old ones leave and new ones enter to replace them at the same instant).

Thanks, Andreas

The autoShutdown parameter can be set to false to instruct the coupling interface to keep going even though there are no more cars in the simulation. See https://github.com/sommer/veins/blob/veins-4.5/src/veins/modules/mobility/traci/TraCIScenarioManagerLaunchd.ned#L55
