Evaluation of Intersection Control Beacon on Xu Song Rural Highway of Beijing City

Abstract

This paper documents the speed reduction impacts of intersection control beacon on rural highway on Xu song road of Beijing City, China. To determine the effect of intersection control beacon on stopping behaviors of drivers, a camera was used to collect valid samples at four times. After data preparation, there were 200 valid samples. In order to research the changing of vehicle speed and relationship of speed and distance, Lagrange's interpolation and Analyses of Variance (ANOVA) methods were used on the speed data to get the mean diagram of mean speeds and the statistically significantce result of distance and speed. The result showed that on rural highway on named Xu song road of Beijing City with intersection control beacon, the speed of vehicles waned decreased 12.87%, moreover, distance has a significant effects on speed. In the distance of speed beginning to decrease was 13 meters from intersection stopping bar, speed changed significantly at about 1.5 merters away from the stopping bar with, significantce level (P) is 0.03, lower than criterion significance significant level (a= 0.05).
