What happens to vehicles when they end their route

问题:

My project is to build a VANET-based smart parking simulation for a small-scale urban area. I dynamically define a route for vehicles to traverse to, then park for 'x' amount of time. Implementation for that is complete, the next step was to define a new exit route for them to exit the simulation after the 'x' amount of time is up. Reason being is that I want to simulate cars vacating parking spaces so that other vehicles may be able to avail of them (I don't want them to simply just to disappear upon reaching the end of their route)

So my question is, is it true that they just exit simulation after route is complete? Is it possible to avoid this?

回答1:

Veins uses SUMO to simulate vehicle mobility. After a SUMO vehicle reaches the end of its route, it is removed from the simulation. You can, however, use SUMO to simulate a vehicle that drives to an intermediate point, parks for a set duration, then starts driving to its final destination. Such a vehicle will simply be marked as stopped/parking and will remain in the simulation.
