Study on the Effects of Speed Camera

Speeding is a kind of common illegal behavior among drivers, and is also one of the primary reasons causing traffic accidents and so the speed management takes on great importance. As the effect of traditional speed control measures is not significant, the speed camera is introduced as a new-style speed control device with the development of high-tech. Many overseas reports show that the effect of speed camera is excellent, especially on the expressway. However, there are only a few studies on the effect of speed camera in China. It bears highly theoretical and practical sense to analyze systematically the effects on reducing speed of the speed camera. This paper takes an urban expressway in Beijing as studying object, and explores the effects on speed control of speed-limit sign, rumble strip and speed camera. The result shows the favorable effect of speed camera on speed control.
