# Traffic Signal Design-Matlab

I need help creating a Gui that can optimize traffic signal timings for a set of traffic lights at the intersection of two roads. The goal is to minimize the average wait time.

The program should accept user-inputs for the traffic flow (cars/minute) in two, perpendicular directions.

E-mail me back at

Thank you

Which part do you need help with? The traffic optimization or the MATLAB GUI? What have you completed so far?
Joga1229 • Mar 7, 2010
the traffic optimization, like the equations to use because i can program the GUI, i just need to know how to setup the optimization

The program should output green light timings(sec), average wait time, and flow capacity(cars/minute) for each road

@Joga: Could you share your current efforts, the program you have tried on your own so far?
Joga1229 • Mar 7, 2010
I have the program ready to go, but i don't think im using the right equations to minimize the average wait time. All i want to know is what equations that are better suited for this program.

The program should output the green light timings (in seconds) for each road as well as the average wait time and the flow capacity of the junction (in total cars per hour). I want to know which equations are the best for each circumstance

Traffic flow simulation - Matlab

Hi crazy engineers, i need help with developing a matlab program for traffic flow control on an signalized intersection and i don't know where to start, have looked in some matlab book but am still stuck. Anyone with ideas...

Joga! you should share your source for make us understand for your help level.. if you put it here, we can discuss it for best algorithm and proper gui..
