Hey, thanks a lot for your answer. I checked the Python example and adapted it to my needs and it worked. I then prepared the minimal example for C++ and while doing that, I think I found the solution. However, I still didn’t fully understand why… Maybe you could give me a little hint, just for understanding. My subscription to both vehicles and persons around a vehicle works fine now. If I only subscribe to persons though, the program crashes straight after starting it. So, if I comment line 66 it crashes (which is what I did in my not-minimal-example and why I asked for help), if I comment line 67 it works and if I don’t comment either of those two lines, it works, too.
You can find the cpp-file here: https://syncandshare.lrz.de/dl/fiWxH8FERhgLwXaDorAyFmW1/SumoConnect.cpp Thanks for the amazing help here!

(at least it does in our tests since version 0.31.0). You may take a look at the tests at https://github.com/DLR-TS/sumo/tree/master/tests/complex/traci/contextSubscriptions Can send a small scenario where it fails for you? regards, Jakob 2017-12-19 17:59 GMT+01:00 Kaths, Jakob <[email protected]<mailto:[email protected]>>: Hello! I was wondering if it’s possible to retrieve values of pedestrians in SUMO by subscription. I know, that in Context Subscription in the Wiki (http://sumo.dlr.de/wiki/TraCI/Object_Context_Subscription) pedestrians are not mentioned. However, I found the corresponding value (CMD_GET_PERSON_VARIABLE 0xae) in the TraCIConstants.h and tried to subscribe, but it failed. Is there a possibility to retrieve position, angle, speed etc. from pedestrians via subscription without modelling them as vehicles? If not, is this planned for the future or could you give a hint of how to implement this? Thanks in advance! Jakob -- Dipl.-Ing.
