摘　　要：随着经济的不断发展,城市圈的不断蔓延扩张,高速公路横穿城市中心,限制了城市的扩容,城市框架的拉大势在必行,高速公路市政化改造可以有效地解决这一类问题。城市道路的交叉口作为道路系统中的重要组成部分,其设计显得格外重要。本文以石家庄复兴大街的交叉口设计为例,主要从交叉口的布局、平面、竖向设计等方面,进一步探析在市政化改造过程中,交叉口设计存在的问题与建议。在市政化理念的指导下,最大限度地优化使用功能。采取优化的辅路平面、调整辅路纵面、增设交通安全设施等一系列措施,更大限度地缓解交叉口的交通压力,完善交叉口的使用功能,保障往来车辆及行人的安全。With the continuous development of the economy and the continuous expansion of urban areas,highways cross the city center,limiting the expansion of the city.The expansion of the urban framework is imperative,and the municipal renovation of highways can effectively solve these problems.As an important component of the road system,the design of intersections on urban roads is particularly important.This article takes the intersection design of Fuxing Street in Shijiazhuang as an example,mainly from the layout,plane,vertical design,and other aspects of the intersection,to further explore the problems and suggestions in the intersection design during the municipal transformation process.Under the guidance of the concept of urbanization,the use of functions has been optimized to the greatest extent possible.By adopting a series of measures such as optimizing the plane of auxiliary roads,adjusting the longitudinal plane of auxiliary roads and adding traffic safety facilities,the traffic pressure at intersections has been alleviated,the use functions of intersections has been improved,and the safety of vehicles and pedestrians traveling between them has been ensured to a greater extent.
