摘　　要：为解决城市道路畸形交叉口交通拥堵、交通组织不合理等问题,提高道路通行能力,对某城市现状畸形道路交叉口进行了改造设计。文章依托张柏路-临空港大道交叉口改造项目实例,分析了现状交叉口存在的交通组织问题,探讨了交叉口改造原则及方法,结合现状交通量调查结果,采用四阶段预测法对远期交通量进行预测,明确了交叉口内主次交通流向的路权大小,并以此作为交通组织的主要依据,经过多方案分析比选,提出合理的交叉口改造策略,即畸形交叉口改造设计时,应依托交叉口内各方向交通流量主次大小,综合考虑通行能力、安全性、景观效果、用地条件、投资造价等方面因素,从而提出最优设计方案。To solve the problems of traffic congestion and unreasonable traffic organization at the abnormal intersection of urban roads,and to improve road capacity,a renovation design was carried out for the existing abnormal intersection of a certain city.Based on the example of the Zhangbai Road Lingkong Avenue intersection renovation project,this paper first analyzed the traffic organization problems existing in the current intersection and explored the principles and methods of intersection renovation.Then,combined with the survey results of the current traffic volume,the four-stage prediction method was used to predict the long-term traffic volume,and the right of way size of the primary and secondary traffic flow direction in the intersection was determined,which was used as the main basis for traffic organization.After multiple scheme analysis and comparison,a reasonable intersection renovation strategy was proposed.When designing the renovation of abnormal intersections,it is necessary to rely on the primary and secondary traffic flow in all directions within the intersection and comprehensively consider factors such as traffic capacity,safety,landscape effects,land conditions,and investment costs to propose the optimal design scheme.
