摘要
为保障大丽高速公路长大下坡路段的行车安全,首先,用风险指数法选出几个危险性比较高的连续长大下坡路段;然后,运用GSRS修正温升模型对危险车型在这些坡段上的制动毂温度进行分析;最后,根据坡段上制动毂的温度变化和沿线的气候特征提出基于光流率和边缘率的改善方法,以及其他系统的安全管理措施和工程改善建议。为大丽高速和其他高速公路长大下坡的安全和防护提供参考。
In order to improve the driving safety for long and steep downgrade on Dali-Lijiang expressway in Yunnan, a serious of downgrade sections with low safety level were selected by risk index method firstly. Then using GSRS revision model, the brake drum temperature of vehicles with high risk was analyzed for these slope sections. Finally, according to the temperature change of brake drum and climate characteristics along the expressway, management measures and engineering recommendations were proposed. Researches indicated that the measures are effective for driving safety on expressway.
