Nearly a century,the Central Bank since a junction on the date,because of its many benefits much traffic engineers of all ages。However,with demand continuing to grow,its shortcomings have gradually revealed。Central Bank intersection had once been the people's opposition,traffic engineers in the unremitting efforts of the traditional circular intersections were continuous improvement,gradually overcome the traditional shortcomings of the Central Bank intersection, the development of the Central Bank intersection of the merits of making Central Bank intersection in Europe and the United States and other countries have been increasingly wide range of applications. However,due to various reasons,the intersection of China's Central Bank building in both theory and practice are relatively backward。So try from the Central Bank intersection,as well as the development of the Central reference design technology,and other key areas on the hope that the current transportation construction has inspired。 This paper first introduced the Central Bank intersection of the characteristics and development experiences,and the Central Bank of organizations optimize the traffic intersection some of the ways。Through the entrance of Ganzhou City Southern,Central Bank intersection of all imports lane vehicular traffic survey to measure the capacity of its Central Bank,and other basic parameters of traffic intersections,in conjunction with urban planning and traffic characteristics,such as traffic parameters of the system optimal design。 Key words: Central Bank intersection;Traffic Organization optimization; 目 录 第一章 绪论……………………………………………………1
