Hi Yushen,

 

I think you can achieve this using TraCi (see https://sumo.dlr.de/docs/TraCI.html).

You could use induction loops and the command “getLastStepVehicleNumber” to check how many vehicles entered within the last simulation step. By checking the vehicle IDs with the command “getLastStepVehicleIDs” you could check how many vehicles with the prefix "A", "B" or "C" entered. See https://sumo.dlr.de/docs/TraCI/Induction_Loop_Value_Retrieval.html and https://sumo.dlr.de/docs/Simulation/Output/Induction_Loops_Detectors_(E1).html

This way you can check if the desired weight was reached and then generate a vehicle using the command "add". See https://sumo.dlr.de/docs/TraCI/Change_Vehicle_State.html

 

Regards,

Giuliana

Betreff: [sumo-user] Generate vehicle according to simulation data

 

Hi,

 

Does SUMO support the following trip generation mechanism:

 

For a certain edge, say edge #1, every 10 vehicles arriving edge #1, generate 1 vehicle staring from edge #1?

 

A more complicated case is:

 

I have three types of vehicles, with prefix ‘A’, ‘B’ and ‘C’. Different prefix has different weight, say ‘A’ has 2, ‘B’ has 3 and ‘C’ has 5. Is it possible for a certain edge to generate 1 vehicle for every 20 weight arriving this edge?

 

Thanks for your attention.

 

Best regards,

Yushen
