It is used to describe the safety situation of traffic facilities and a quality indicator that traffic facilities provide safety services for traffic participants. This paper systematically introduces the domestic and international research status, concept definition, application and research content of the level of safety service, studies the selection of the classification index, proposes the method of division of safety service level of σ theory, and quantifies the safety of expressway in China plain and mountainous areas Service Level. As a new method for quantitative evaluation of traffic safety, the level of safety service can not only be used to describe the potential of improving traffic safety, but also serve as a reference for the implementation of safety renovation project.
