Re: [sumo-user] Question relativ to context subsciptions
Hello,
- PersonScope::getPosition3D is implemented (TraCIAPI.cpp, line 2971)
- getAngle and getLength are indeed missing in the C++ client (https://github.com/eclipse/sumo/issues/5172)
- getSlope is not yet implemented on the server side for persons (https://github.com/eclipse/sumo/issues/5171)

patches are welcome and should be much easier compared to subscription filtering
best regards,
Jakob

Hello Jakob,

 

thank you very much for your quick answer and for your help. I tried it but still facing some strange behavior.

 

1-     It seem that these variable  VAR_POSITION3D , VAR_ANGLE , VAR_VEHICLECLASS , VAR_LENGTH are not implemented yet for person in C++, although we can get all these value for person by using Traci function command.

 

2-     I also get this error bellow, when I use the variable Slope (VAR_SLOPE) . Please Jakob can you give more hint ?

 

Thank you very much

you need to use two subscribtions. one for vehicles and one for persons:

vehicle.subscribeContext(vehID, CMD_GET_VEHICLE_VARIABLE, range, vars, begin, end)

vehicle.subscribeContext(vehID, CMD_GET_PERSON_VARIABLE, range, persoVars, begin, end)

Hello everyone

I have a question relative to the context subscriptions of sumo.

I want to use the context subscription to filter every objects around the ego vehicle. But I’m facing the issue that the class person is not handle as a vehicle class. The consequence is that by using vehicle.subscribeContext pedestrian will not be considered. I wanted work around that by using person.subscribeContext(vehID, CMD_GET_VEHICLE_VARIABLE, 10000, vars, 0, 3000); but here the parameter vehID would be PedestrianID, and then in this case, I would take the person around a define PedestrianID. But want I want is to take pedestrian around a defined VehicleID (Ego Vehicle). Can you help me on this part, how can I find here a suitable solution. There is a way to have this information by using context subscription ?

Thank you very much for your help.

 

Best regards

 

Christian Wabo
