以赣州三康庙环岛为例,分析其交通问题的根源之所在,对其采用了不同程度的改善措施,并对不同措施进行了交通评价,从而得到了合理的解决方案。通过与上海五角场环岛、陆家嘴环岛等相关案例的类比,对城市环形交叉口常见的交通问题、解决思路及措施进行了总结,可供类似项目参考。

Taking Ganzhou Cankangmiao Island as an example,this paper analyzes the causes of its traffic problems,takes the different improvement measures for the traffic problems and evaluates the traffic for the different measures so as to achieve the reasonable solving scheme.Compared with the relative cases of Wujiaochang Roundabout and Lujiazui Roundabout in Shanghai,this paper summarizes the common traffic problems,solving ideas and measures of urban roundabout,which can be referred for the similar projects.
