Abstract
Almost all the populated countries especially under developed countries are facing traffic problem in their major big cities like Karachi, Lahore, etc in Pakistan. There are number of possible solutions as widening the roads, make overheads, and make different routes to same destination etc but these all require healthy resources. There is a requirement to optimize the current road model by properly allocating the time to traffic signals. Researchers have proposed different simulation models and used various approaches to optimize the traffic light signals. In this paper we have provided information about THE traffic light simulator that is implemented using Visual Studio 2008 in C#. We have also illustrated the genetic algorithm (GA) approach that we have used to optimize the traffic light signals using THE simulator. Result shows that our simulator works better and GA provides better results as it matures.
