Maria, Thanks for your reply! If I have 3000000 vehicles in my simulation scenario, the suggested Traci command is going to set a parameter for each vehicle, like
- use Traci to find a list of vehicles is running and are going to insert in the simulation, - set a new rerouting period for these vehicles. - I am wondering, is it a time-consuming one? Are there some other methods I could do it quickly and easily? Best regards, Jane On Tue, Sep 8, 2020 at 3:26 AM <[email protected]> wrote: > Hi Jane, > > > > I think you could do it using Traci.
