| 摘 要： | 为了便于高速公路安全的分析及事故预测模型的建立,明确了高速公路"立交安全影响区"这一概念,分别以500 m和100 m为统计单元,研究立交桥两侧5 km范围内的事故发生水平.结果表明:以500 m为间隔划分单元是合适的,能满足实际的需要,通过比较立交中心桩号两侧1 km、2 km、3 km和4 km范围内、外的事故发生水平,确定了立交安全影响区的范围,并给出了理论上立交区的事故水平分布图.

| Abstract: | The concept"Safety Influencing Range of Freeway Interchange"was defined in this paper.The highway accident distribution was studied by taking 500 m and 100 m as the statistical unit separately in 5 km range on both sides of the interchange,and the result indicates that it is suitable to take 500 m as statistical unit,and based on analyzing and comparing the accident frequency in and outside of 1 km,2 km,3 km,4 km range respectively,the safety influencing range of freeway interchange was confirmed.The theore... |
