摘要
针对山区道路交通安全现状,提出安全度概念,分析了山区道路行驶车辆的制动器不失效、车辆横向不失稳等安全性条件。并利用车辆参数、道路参数和能量平衡的原理,建立了山区车辆行驶中车路耦合的交通安全条件和安全度模型。
The concept of safe degree is defined by analyzing the present traffic safety conditions of mountainous highways.This paper analyzes the safety conditions on mountainous highways,such as brake temperature and lateral vehicle stability.A safety model for mountainous highways is established based on the parameters of vehicle and mountainous highways and the law of conservation of energy.The model is to provide not only a theoretical basis for the enhanced safety with early warning and control,but also a theoretical reference for the design of the mountainous highways.
