| [sumo-user] question about about the subscription with the traci.constant DISTANCE_REQUEST |
|
Hello sumo people, Hello Jakob, I have a question about the subscription, of the traci.constant “DISTANCE_REQUEST”. I want to take the distance between Ego and every traffic around the EGO-Vehicle. I tried to do that in one step using “SubcribeContext”.
Here is the command that I used: “traci.vehicle.subscribeContext(‘EGO’, tc.CMD_GET_SIM_VARIABLE, 42, [tc.DISTANCE_REQUEST])” But I think that the constant “DISTANCE_REQUEST”, need to have two parameter. The vehicles-ids of the two cars. In order to get the distance between this two vehicles. I think it’s why I’m getting “None” as Output of this assertion.
My question is to know it’s someway to get this relative distance of traffic around the ego vehicle to the ego vehicle itself in one step? Or should I do that in two steps:
The first one gets the vehicle Id around the ego vehicle The second one use the function getdistance2d (ego,traffic), to have the distance between Ego the surrounding vehicle.
