I am using Omnet, SUmo and Veins to simulate Vanets. The issue I face is that with certain maps, not all cars in the route file are spawned, at least not when they are supposed to. From what I understand it is because there is "not enough space in the network". I find it weird because the map I currently have covers 5*4 Manhattan blocks and should be big enough to accommodate thirty vehicles.

When I use departLane and departPos with "free", cars spawn, but the simulation fails randomly. I used a much bigger map with thirty vehicles and that one worked fine.

Any ideas, thanks in advance.

At depart time SUMO does not check for general space in the network but on the given departLane (which defaults to the rightmost usable lane) of the first edge in the route that's why vehicles are delayed. You already found out what to do against it, use departLane="free".

As for the second problem please give at least the error message preferrably with a more detailled description and the SUMO version.
