Abstract

Traffic lights are available in almost all cities and towns worldwide. They solve many traffic congestion problems, save numerous human lives and avoid frequent automobile accidents. Optimizing the operation of traffic light systems in roads is essential for any city's economy, safety and environment. Simulation technology is probably the best tool to analyze and optimize the operation and design of traffic light systems. The increasing use of automobiles in cities has lead city administrators and local governments to install traffic lights and detectors in large quantities in order to avoid accidents and optimize the movement of automobiles and humans. Although signalization can solve traffic conflicts at the intersections, it causes stoppage. The chief objective of optimal traffic control is to improve system mobility and throughput at reduced delays. Delays and stops are not only irritating and pricey to drivers and passengers, but they also add to air contamination and energy use. In this paper, we analyze and demonstrate how the timings of a traffic light system are calculated in order to determine the optimum and proper timings needed to optimize traffic flow.
