摘　　要：错位交叉口是城市道路短间距交叉口的特殊情况,此类交叉口因间距较短且反向错位常常导致城市道路拥堵或事故频发,是城市道路交通改造的痛点和难点.本文以开放大道与达阳路交叉口为例进行交通组织优化研究,并运用Before-and-after方法的思想进行了改造前后的对比.对比发现:改造之后,该交叉口事故率下降87%、整体延误分别下降70%.本文的交通组织优化方法对于城市道路错位交叉口的改造具有实际借鉴意义.Misaligned intersections are a special case of short-spaced intersections on urban roads.Such intersections often lead to urban road congestion or frequent crashes due to short distances and reverse misalignment,which is a pain point and difficulty in urban road traffic reconstruction.This paper takes the intersection of Kaiyang Avenue and Dayang Road as an example to study the optimization of traffic organization,and uses the Before-and-after method to make a comparison before and after the transformation.The comparison found that after the renovation,the crash rate of the intersection dropped by 87%,and the overall delay decreased by 70%.The traffic organization optimization method in this paper has practical reference significance for the reconstruction of urban road misaligned intersections.
