城市道路平面交叉口设计探讨

Discussion on Design of Urban Road Planar Intersections

在城市道路设计中,交叉口最为复杂,也是设计人员需要重点研究的对象,交叉口设计是否合理,将会影响整条道路的通行效率,交叉口的布置也是提升道路景观形象的重要节点。平面交叉口通过合理的渠化、导流岛、专用车道等精细化设计可以达到“少投资、高效果”的成效。充分挖掘交叉口时间和空间资源,发挥道路最大潜在通行能力是城市道路设计中最具性价比的措施。

In the urban road design,the intersection is the most complex,but also designers need to focus on the research object,the intersection design is reasonable,will affect the efficiency of the whole road,the layout of the intersection is also an important node to enhance the road landscape image.Planar intersection through reasonable channelization,diversion island,special lane and other fine design can achieve the effect of"less investment,high effect".It is the most cost-effective measure in urban road design to fully tap the time and space resources of intersections and give full play to the potential capacity of roads.
