Modeling and simulation of traffic lights on the high contrast and brightness conditions and structure

Nowadays, the use of intelligent control systems to reduce human error is one of the most popular research fields. Design and implementation of such controllers requires to actual knowledge of the environment conditions. Traffic lights as one of the inputs of intelligent control systems are significant. usually the traffic lights have the various physical structure. also, generally in image processing images is provided by a digital camera therefore having similar characteristics of images is a necessity. The light of environment conditions as backlight can lead to different results in the image processing. It seems, design and practical implementation of this system with acceptable performance will be hard achievable without a proper model for different lighting conditions. In this study we propose a consistent and comprehensive model for traffic lights in various lighting conditions, such as day and night conditions.
