Yujia Tian, Hong Chen, Baixiu Liu, Dianliang Xiao · 2010
With the rapid development of mountainous expressways, the traffic accidents increase obviously on bridge-tunnel sections, which brings new challenges to traffic safety protection on mountainous expressways. Based on the traffic accident data of Tongchuan section on Baotou-Maoming expressway, this paper carries out an in-depth study on traffic safety of mountainous expressway bridge-tunnel sections and sets up the safety evaluation system of bridge-tunnel sections on mountainous expressway based on Bayesian network. It is helpful to further identify potential threats and to provide guidance for future construction.
