摘要
借鉴路网可靠性分析方法,定义交叉口安全可靠性的概念,提出基于冲突概率分布的安全可靠度理论计算方法以及基于综合交通冲突率的安全可靠度计算方法,结合实例实现交叉口安全评价的定量分析。
According to the reliability analysis methods of road network, the paper presents the conception of intersection safety reliability. What＇s more, the computation methods of safety reliability which arebased on conflict probability distribution and comprehensive traffic conflict ratios are deduced. With the consideration of practice, quantitative analysis on intersection safety comes true.
