基于国内外交通事故鉴别方法,结合山区高速公路特点及其事故特点,提出改进的鉴别指数与非定长分段法相结合的适合山区高速公路的混合鉴别方法,最后在包茂高速(西安—榆林)铜川段进行实例验证,证明了该方法的有效性。

Based on the current domestic and foreign identification of accident-prone location, and with the characteristics of mountain area freeway and its accidents＇ characteristics, one kind of effective mountainous area freeway＇s accident-prone identification method is proposed, namely the distinction index-random length stepwise method.
