If you can't keep the vehicles in the simulation and they exit when reaching their destination, it means that you are actually generating the vehicles. Any vehicle that you generate will either move towards some destination and get disposed of eventually or stop (if you want). What do you mean by a random walk? Do you want the vehicles to just drive around without a destination?

I already checked traci and randomtrips but I cant seem to find a way to generate routes automatically and let the vehicles stay inside the simulation. 

if I generate them by defining trips, they reach to their target and leave the simulation. I can’t add them using traci because I need to specify routes.

What I am trying to do is really simple, I dont know why there’s no straightforward way to generate a specific number of cars on specific roads and let them randomwalk for a specific number of time.

- you can add cars via traci (traci.vehicle.add) : https://sumo.dlr.de/docs/TraCI.html

- you can write a script that generates xml inputs for the simulation (i.e. https://sumo.dlr.de/extractTest.php?path=complex/tutorial/traci_tls/plain)

- you can use ready-made scripts to generate traffic (also with specific numbers): https://sumo.dlr.de/docs/Tools/Trip.html#randomtripspy

  (and there are many more tools for traffic generation in sumo/tools)

Hi,
What is the best practice to initiate a simulation with a specific number of cars. I was using an additional file and input for the first time interval the occupancy but apparently it is not working. After researching it seems like there’s no straightforward method of adding lets say 5 cars to road 1 and 2 cars to road 2 and creating routes for these cars using a script?
Regards,
Toprak
