_______________________________________________Hello Jakob,
Thank you very much for your answer! Thank you also for the hint. I’m trying to use the subscribe function of SUMO in CarMaker. But it seems that, it’s not possible to subscribe and get the value for more than two constant values.
When I tried to use that function:
“traci.vehicle.subscribeContext(vehID, tc.CMD_GET_VEHICLE_VARIABLE, 200, [tc.VAR_POSITION3D, tc.VAR_ANGLE, tc.VAR_SLOPE])”
As you can see I want to subscribe 3 constant values, but I just got 2 values (position3d and Angle). (See picture down).
The first key it’s always “vehicle id”
Second key is “position3d”
And Third key is “angle”
Please do you have here some hint how can I retrieve these 3 constant.values by using the subscribe function of SUMO?

Hello,
1) we don't have a set date for 1.1.0 yet but I have some hopes that it will be in December. I don't think that issue #4569 will be fixed soon because the developer of that code is extremely busy with other projects.
2) There is yet no capability to retrieve values from the ssm device via TraCI. Again, the developer for this is currently not available to add these features.
Currently, you can try to reconstruct critical encounters either via
- fcd-output (it includes position and orientation of all vehicles)
- traci. (you can retrieve position and orientation of all vehicles, also you can selectively retrieve vehicles in a given range around another vehicle)
regards,
Jakob

Hello Jakob, hello Sumo-Community,
Please can you help to clarify me on some open point from my side? These Points concern in general the analyzing of critical scene using ssm device. These points are:
1- Please Jakob do you have some idea, when about you can delivered the SUMO release 1.1.0. Because the issue from ssm (see https://github.com/eclipse/sumo/issues/4569) would be fixed in the release of SUMO 1.1.0. Or maybe is there some possibility to get that issue fixed before that release?
2- I wanted also to know if we have somehow the possibility to retrieve online some value inside of ssm-device (as example to get online when a potential conflict area would happen).
The motivations here are:
- To get apart from the trajectory of vehicle (ego and foe) that are critical also the position and orientation of other traffic object, which is inside the conflict area.
- To also have the yaw and slope apart from the trajectory of the traffic object. Because it seem that the in the file generated from ssm there is no information about orientation of the traffic object.
If we can have some possibility to know online, when some conflict area would happen, we can also take these values directly online and save it in a file. So we can have a file which contents the information that we really need. And from the ssm device, we can know the time, when a potential conflict area would happen.
I would be very glad if you can give me some hint, and possibilities, that SUMO can offer me to get this information in the point 2.
To summarize these information are:
o Position and orientation of the critical vehicles (foes and ego)
o Position and orientation of vehicle which is inside a potential conflict area.
I hope to read you very soon!
Thanks in advance!
Best Regards
Christian
