Hi Michael,
thank you so much for your help. With your explanation I better knew where
to search.
Please let me extend your answer by the following link, which is, what I
found:
http://sumo.dlr.de/wiki/TraCI/Object_Context_Subscription
And yes, there already is a representation for that in TraCI4Matlab
(function subscribeContext() )
Best regards,
Marcus

Hi Marcus,
> what do you think is the most efficient way to get a car's environment
like other cars, junctions etc.
supposing you want to use TraCI, have a look here:
<http://sumo.dlr.de/wiki/TraCI/Object_Variable_Subscription>
http://sumo.dlr.de/wiki/TraCI/Object_Variable_Subscription
It's a quite technical description though, but the main idea is that you can
say: Tell me for each timestep the speed of every vehicle in radius
10 aroung junction 1 (where you can of course specify the type (vehicle,
edge, ...) and the instance of the reference point as well as the type and
the variables (speed, pos, ...) you are asking for.
It is implemented at least in the python client, I don'tknow about Traci4J
and Matlab.
Best regards,
Michael
