扬州市万福快速路立交方案比选

Comparison and Selection of Yangzhou Wanfu Expressway Interchange Schemes

城市道路快速化已成为提升居民出行效率的有效手段,而老城区过于成熟的地块开发大大增加了道路快速化设计难度,故而全面分析设计重难点并进行方案的经济合理性研究显得尤为重要。依托扬州市万福快速路东延项目,通过对交叉口流量、住宅光照和噪声影响以及交叉口渠化长度等方面的综合分析,同时结合扬州市快速路网规划,确定了万福路-金湾路节点互通立交的功能定位、车道规模、建设选型,并分析了右转匝道采用不同设计速度时的利弊。

The rapid transportation of urban roads has become an effective mean to improve the travel efficiency of residents,while the development of old towns already mature greatly increases the difficulty in the design of rapid transportation of roads.Therefore,it is particularly important to comprehensively analyze the key and difficult points of the design and study the economic rationality of the scheme.Based on the Yangzhou Wanfu Expressway East Extension Project,through the comprehensive analysis on the intersection flow,residential lighting and noise effects,and intersection channelization length,and combined with the planning of expressway network in Yangzhou,the functional positioning,vehicle lane scale and construction model selection for the interchange at the node of Wanfu Road-Jinwang Road are determined,and the advantages and disadvantages of using the design speeds for the right turn ramps are analyzed.
