Hi Lin,

 

you can adjust it like any other car-following model parameter:

 

• add an attribute cc1="<YOUR_VALUE>" attribute to the vType element definition
• change it during the simulation with TraCI with traci.vehicletype.setParameter(vehID, "cc1", "<YOUR_VALUE>")

Best regards

Thank you for your answer!

Do you know how to adjust the parameters, i.e., spacing time for W99 car following model?

 

Best,

Hi everyone,

 

Does anyone know the default parameters using for the Wiedmann car following model and W99?

 

https://sumo.dlr.de/docs/Definition_of_Vehicles%2C_Vehicle_Types%2C_and_Routes.html#car-following_model_parameters

This website does not have the exact values used for Wiedmann car following model.

 

Does anyone know how to adjust the spacing time(cc1) of Wiedmann car following model?

 

Best regards,

Lin
