The Simulator
The Simulator is where the real exploration of traffic interaction takes place.
In the Simulator window the loaded map is animated with its road users and
the traffic lights show their status. The only changes that can be applied in
the Simulator are those concerning the speed of cars in the system, however
you do have access to statistics that the simulator generates as it runs.
