Analysis of vehicle speed control in highway tunnel sections

Abstract

China's mountainous highway tunnels are prone to accidents, and the main types of accidents are tailgating and wall crashes. On the basis of analyzing the distribution pattern of highway traffic accidents, we deeply investigate the impacts of people, vehicles, roads, and the environment, and put forward an analytical method for the causes of tunnel accidents by using the method of Principal Component Analysis, and put forward a method of setting up speed-control based traffic signs based on the characteristics of the drivers, and establish a strategy of setting up traffic signs in tunnels to perfect the overall safety protection technology of the dense section of tunnel of mountainous highway of China and to enhance the safety of tunnel road sections, which is of theoretical value and practical significance, and provides a technological support for the safe operation of the highway of mountainous areas of China.
