Dear Hwang

I have found your simulations very interesting. I was looking for such simulation because I had an argument with a friend regarding the optimal traffic light timing. You have some simulations but I was looking for a simulation with the following features:

[li]One junction only.
Ability to control also the acceleration and delay time.
Ability to set a timer so that the simulation will take only the predefined timer.
Longer range for the lights durations. [/li]

[/list] Do you have such simulation?
