摘　　要：从提高高架快速路下匝道交叉口通行效率出发,针对高架下匝道和地面交叉口衔接段存在普遍的拥堵现象,对其交通组织进行优化设计,探讨其优化方法。并以郑州市陇海路-嵩山南路交叉口为例,对其交通设计进行优化,并通过VISSIM仿真,对优化前后方案进行评价,发现其改善后交通运行条件明显提高,验证该方法合理有效性。In order to improve the traffic efficiency of the off-ramp intersection of the elevated expressway,aiming at the common congestion in the connection section between the off ramp and the ground intersection,this paper optimized the traffic organization and discussed the optimization method.Taking the Longhai Road-South Songshan Road intersection in Zhengzhou as an example,the traffic design of the intersection was optimized,and through the VISSIM simulation,the scheme before and after the optimization was evaluated,and it was found that the traffic operation conditions were significantly improved after the improvement,which proved that the method was reasonable and effective.
