Re: [sumo-user] Simulating "count lines"
Hello,
unfortunately, there is currently no convenient way to retrieve the count. You might be able to improve your script by calling traci.inductionloop.getVehicleData because this clearly distinguishes between vehicles on the detector and vehicles that have passed it.
Retrieval of counts is a known issue and should be solved via https://github.com/eclipse/sumo/issues/2139

regards,
Jakob

Hi,

 

I’d like to simulate a count line in a lane, to know how many vehicles have gone passed it (that is, completely passed).

 

My first idea was to use a single induction loop, but unfortunately from Traci you don’t get the information of how many vehicles have actually passed it.

 

So far what I’ve done is to use the loop and keep track of the vehicles inside it (with getLastStepVehicleIDs) at each step, and simply check what ids have “disappeared” from the previous step (so those vehicles left the loop).

 

I’m not convinced this is the best way to do it, but cannot find any other sensor type to compute this.

 

Anyone has any suggestion?

 

Thanks,
