Illumination change underneath bridge influences driver behavior

Illumination change can influence driver behavior. Especially, glare light can make driver blind and lost vision, caused accidents happen. Driving behavior is a complex psychological activity process, and many researchers want to find common driving behavior characteristics. This paper studied driving behaviors, found in big cities, like Beijing, bridge is one factor can cause illumination change, data shown that mostly driver would change their driver behaviors instinctive, vehicle acceleration changed in a regular wave. Degree of illumination change will cause different acceleration variations. This paper discussed the reason how this phenomenon happen.
