Hi Jin,

 

With the command traci.vehicle.setType() you are assigning a new vehicle-type to the vehicle. So you are changing from AudiTT vehicle-type to AudiA2, this means that not only the car following model will be changed but also all other parameters of vehicle-type, for example the maxSpeed.

I think there is no other way to change the car following model in Traci. You can check the following links for more information:

https://sumo.dlr.de/docs/TraCI/Change_Vehicle_State.html

https://sumo.dlr.de/docs/TraCI/Vehicle_Value_Retrieval.html

Giuliana

Hello:

 

Hope this email finds you well

Here is my question:

 

I know we can use traci.vehicle.setType("a new type") to change the car-following mode, but is there any way to preserve the same ID name

with different car-follow-type.

 

For example, in the route file:

<vType id="AudiTT" maxSpeed="15.00" carFollowModel="IDM"/> <vType id="AudiA2" maxSpeed="15.00" carFollowModel="Krauss"/>

<vehicle id="vehicle_0" type="AudiTT" depart="0.00" route="route_0" />

 

For example, in the route file: I have a vtype "AudiTT" with IDM model and Audio A2 with Krauss model

when I change the type for "vehicle_0" the whole thing has been changed

is there a way to assign "Krauss" to Audi TT with Traci python in runtime?

 

Best regards

 

Jin
