文章从停车视距模型出发,分析了货车停车视距模型参数,通过试验方法确定了驾驶员反应时间,利用动能定理,经大量制动试验,建立了不同路面条件下速度与制动距离的关系,提出了不同速度下制动系数,基于此,首次建立了我国公路货车停车视距,并分析了不同线形条件下的货车停车视距保证,为工程设计人员提供参考,采用货车停车视距对相关路段进行检验,能够有效的保证行车安全。
Based on the model of parking distance, the article analyzes the parameters of the model of vehicle parking sight distance, and determines the reaction time of the driver through the test method. Based on the kinetic energy theorem and a large number of braking tests, the relationship between speed and braking distance under different road conditions is established , Proposed the braking coefficient under different speeds. Based on this, the first time set up the line of sight of the truck parking on the highway in our country, and analyzed the line of sight guarantee of truck parking under different linear conditions, providing references for engineering designers, Related sections for testing, can effectively ensure traffic safety.
