| Re: [sumo-user] device to check the distance of one vehicle relative to other one in a define radius |
|
Hello Jakob, Thank you for the hint. Based on the example in the link: http://sumo.dlr.de/wiki/TraCI/Interfacing_TraCI_from_Python#Context_Subscriptions
. I wrote the same in Matlab using:
“traci.junction.subscribeContext('5', traci.constants.CMD_GET_VEHICLE_VARIABLE, 42, {traci.constants.VAR_SPEED, traci.constants.VAR_WAITING_TIME})” But it’s still the same issue that we had since the last version of SUMO.
You can see this issue in the picture bellow. I want to know If it’s with the new version of SUMO until impossible to use TRACIMATLAB? It’s also the same behavior
by using TRACI-C++. Do you have any idea to Work around that issue?

I have a question relative to the device in SUMO. What I want to do is to check the relative distance from my ego-car with in other one inside a define radius. For that reason I
have basically the possibility to use Traci function, perform the calculation of all vehicle in the network and just take the one, which the value is lower than a define value. But to be able to run the simulation quickly, that’s not the best way to do that.
For this reason I want to know if we have in SUMO some device, which enable me to have the relative distance from the ego-car with traffic car, which is inside a define radius. By using the ssm.device, we just have this information inside a conflict area.
Thank you very much
