Re: [sumo-user] How to reach a certain density level using traCI?

[Jakob Erdmann <namdre.sumo@xxxxxxxxx>]

Hello,

you can call traci.vehicle.add repeatedly with the same routeID. just make sure to use a new vehicleID every time.

Alternatively, you could call sumo with option --scale to easily scale the amount of traffic up or down.

Hi all,

I want to keep generating vehicles until the network reaches a certain density level. I know sumo has the option to give a limit on the number of vehicles, which is one of the options. But do there exist better approaches? 

I want to do multiple experiments with different density levels, so it would be best if I can do it in a loop with traCI.  

I tried traci.vehicle.add, and found an old question says that route id cannot be repeated. 

In a word, how can I use traci to generate flow until we reach our desired density?

Thank you in advance,

Hao
