摘要
为量化公路作业区段对行车风险的影响,文中基于势场理论,针对公路作业区段的安全风险进行了系统性分析与建模,通过引入相对运动思想,结合作业区的多重风险因素,加入等效质量和伪距离概念,构建了公路作业区段的安全风险势场模型,并对封闭不同的车道数、不同限速值以及不同渐变率上游过渡区的情况进行了量化分析和说明。研究结果表明:公路作业区的风险分布在不同情况下具有纵向和横向差异,其封闭车道数、上游过渡区渐变率及限速值对行车安全风险具有显著影响,故在进行作业区布设时,应综合考虑各种影响因素,以确保公路作业区的布设合理性。文中通过多点微分联立方法构建的势场模型,能够灵活适应不同作业区设置下的风险分布;同时首次将势场理论应用于公路作业区段的行车安全风险建模,且所建立的模型具有一定的泛化能力,可为公路作业区的安全管理提供科学的量化工具和理论依据,有助于制定更加有效的安全管控策略,提升公路作业区的整体安全性。
To quantify the impact of highway operation section on driving risks,this study systematically analyzes and models the safety risks of highway operation section based on potential field theory.By introducing the concept of relative motion and integrating multiple risk factors of work zones,the equivalent mass and pseudo-distance concepts are incorporated to construct a safety risk potential field model for highway operation section.This model is applied to quantitatively analyze and elucidate the effects of different lane closures,speed limits,and upstream taper rates.The results indicate that the risk distribution within highway work zones exhibits longitudinal and lateral variations under different scenarios,with lane closure,taper rate,and speed limits significantly influencing driving safety risks.Therefore,when designing work zones,it is essential to comprehensively consider various factors to ensure the rational layout of highway work zones.The potential field model constructed through the multi-point differential coupling method demonstrates flexibility in adapting to risk distributions under various work zone configurations.Moreover,this study is the first to apply potential field theory to model driving safety risks in highway operation section,and the established model with certain generalization capabilities can provide a scientific quantitative tool and theoretical foundation for the safety management of highway work zones,contributing to the formulation of more effective safety control strategies and enhancing the overall safety of such zones.
