Overview and prospect of the application of risk prevention and control facilities on freeways
The reasonable application of freeway risk prevention and control facilities can significant-ly reduce traffic risks.This paper first reviewed and summarized the research status of freeway risk prevention and control facilities and divided them into non-electrification and electrification preven-tion and control facilities.Second,on this basis,the paper summarizes the effect of non-electrifica-tion and electrification prevention and control facilities on risk prevention and control of freeways,along with the critical issues in the study.The application scenarios and effectiveness of different electrification risk prevention and control facilities are discussed.Third,the application effects of the risk prevention and control system comprising electrification facilities in various typical scenarios are further analyzed.Finally,the results of the literature review and future developments are summa-rized.The literature review results demonstrate that the risk prevention and control facilities and sys-tems of the freeway have a satisfactory effect in different scenarios.The non-electrification preven-tion and control facilities are limited by their physical characteristics,and certain defects and defi-ciencies in risk prevention and control exist.The electrified risk prevention and control facilities and risk prevention and control systems should be extensively used,and the prevention and control of traffic risks such as traffic congestion and bad weather should be increasingly improved.The results of this study can provide some reference for the setting and application of risk prevention and control facilities on freeways in the future.
