Hi Noa,
I understand that you want to know if there are any built-in functionality to make cars obey traffic lights in a Road runner simulation.
In RoadRunner, the pre-configured light timing only affects the visual appearance of the traffic lights in the scene. It doesn't have any built-in functionality to control the behavior of the cars in response to the lights.
To simulate the behavior of cars obeying traffic lights, you would need to implement custom logic in your simulation.
Implement logic for the cars to detect the state of the traffic lights and respond accordingly in a MATLAB script and attach it as a behaviour to your cars.
Follow this documentation to know more about attaching behaviors to road runner actors: https://in.mathworks.com/help/driving/ug/overview-of-co-simulating-roadrunner-with-matlab-and-simulink.html#mw_f89c9c1c-224c-4b16-a639-d72e8ac40387
