国道G110北京段是为货车提供服务的专用通道,其中延庆县城-昌平德胜口路段为连续下坡,成为运营安全关注的重点。国道G110以6轴集装箱为典型代表车型,特殊的车辆组成及道路特征决定了不能应用常规的“速度一致性”评价方法进行定量结合定性的分析方法。根据连续下坡制动失灵的事故特征,采用货车制动榖温升模型的技术手段对G110(延庆县城-昌平德胜口)连续下坡路段运营安全现况进行分析,并且根据评价结论有针对性地提出安全建议与对策。
State Road G110 Beijing section is dedicated to providing services for trucks, including Yanqing County - Changping Deshengkou section of the continuous downhill, becoming the focus of operational safety concerns. State Road G110 to 6-axis container as a typical representative of the model, the specific vehicle composition and road characteristics of the decision can not be applied to conventional “speed consistency ” evaluation method for quantitative analysis combined with qualitative analysis. According to the accident characteristics of continuous downhill braking failure, the operational safety status of G110 (Yanqing County - Changping Deshengkou) continuous downhill section was analyzed by technical means of temperature rise model of truck brake 榖, and according to the conclusion of the evaluation Put forward safety recommendations and countermeasures.
