公路交通事故产生的原因是多方面的,但主要与驾驶员的素质、车辆技术状况、公路状况有关。据日本《铺装新设计法》所载,雨天的交通事故约87％与路而滑溜有关。经对我市102国道雨天多发事故路段的调查,也证明了雨天交通事故多发生在路表比较光滑的路段。从调查所见,雨天易发生事故路段的路面摩擦系数多在40以下,路面构造深度多在0.3mm以下。由于路表宏观构造深度小,表面光滑,在雨天路面潮湿状态下,车轮同路面之间形成一层水膜,降低了车轮同路面的附着力,在车轮转向、刹车、改变车速的情况下,极易
The causes of road traffic accidents are many, but mainly related to the quality of drivers, vehicle technology, road conditions. According to Japan’s “New Design Law”, about 87% of traffic accidents in rainy days are related to slippery roads. After the city of 102 State Road accident investigation of rainy days, also proved that traffic accidents occurred in rainy days more smooth road sections. According to the survey, the pavement friction coefficient of road sections prone to rainy days is more than 40, and the pavement depth is more than 0.3mm. Due to the macrostructure depth of the road surface is small and the surface is smooth, a layer of water film is formed between the wheel and the road surface under wet conditions of the rainy day, reducing the adhesion of the wheel to the road surface. Under the condition that the wheels are steered, braked and the vehicle speed is changed, Very easy
