随着我国城市化进程不断加速,人口向城市的快速聚集,以及汽车保有量的迅猛增加,城区内交通堵塞现象日益严重。尤其是在老城区内,受土地、空间布局的限制,交通资源已达到极限。因此,充分利用有限的交通资源,对老城区道路扩容改造,优化交通组织管理,将是短时期内解决老城区交通拥堵的有效方法。本文结合工程实例,探讨了老城区主干道路扩容改造设计过程中需要考虑的平、纵、横设计以及管线、照明及交通组织设计问题,为类似工程提供参考。
With the accelerating process of urbanization in our country, the rapid accumulation of population to the cities and the rapid increase in car ownership, traffic congestion in urban areas is becoming increasingly serious. Especially in the Old City, due to the limitation of land and space layout, traffic resources have reached the limit. Therefore, making full use of limited transportation resources to expand and rebuild roads in old urban areas and optimize the management of transport organizations will be an effective way to solve the traffic congestion in old urban areas in a short period of time. In this paper, the design examples of flat, vertical and horizontal design, as well as the design of pipeline, lighting and traffic organization in the process of expansion and retrofit of main roads in old city are discussed in this paper, which will provide references for similar projects.
