Rubio TI - Numerical Simulation and Natural Computing applied to a Real World Traffic Optimization Case under Stress Conditions: T2 - Computer Modeling in Engineering \& Sciences PY - 2009 VL - 50 IS - 3 SN - 1526-1506 AB - Urban traffic is a key factor for the development of a city. There exist many different approaches facing traffic optimization. In our case we have focused on traffic lights optimization. We have designed and tested a new architecture to optimize traffic light cycle times. The purpose of this research is to demonstrate the good performance of our architecture in a congested scenario. We have simulated several congestion situations for a very large real world traffic network - "La Almozara" in Zaragoza, Spain. Our results seem encouraging in this extreme situation. As we increase the load in the network we get a the better traffic behavior of our architecture. Finally, new research directions are presented.
