高速收费站片区交通组织优化与城市门户形象提升一体化设计实践——以张掖东南门户地区为例

Integrative Design Practice for Traffic Organization Optimization and Urban Portal Image Promotion in High-Speed Toll Station Node—— A Case of the Southeast Portal Area of Zhangye

高速收费站节点是城市对外的门户,也是展示城市形象的关键节点,对于旅游城市尤为重要。然而高速收费站区域普遍存在着交通组织复杂、景观元素单一、门户整体品质不高的问题,需要将高速收费站节点的交通组织优化与城市门户形象提升做一体化设计。文章通过分析张掖东南门户地区的建设诉求,通过VISSIM仿真软件对交叉口进行渠化改善,形成更多的绿地空间,同时结合丹霞元素的景观打造,实现了门户地区形象的一体化提升,具有一定的实用参考价值。

The high-speed toll station node is not only the gateway to the outside of the city,but also the key node to display the image of the city,which is particularly important for the tourist city.However,there are many problems in the area of high-speed toll stations,such as complex traffic organization,single landscape elements and low quality of the portal.It is necessary to integrate the optimization of traffic organization of high-speed toll station nodes with the promotion of the image of the city portal.Through the analysis of the construction demands of the southeast portal area in Zhangye,this paper improves the channelization of the intersection through VISSIM simulation software,and forms more green space.At the same time,combining with the landscape construction of Danxia element,it realizes the integration of the portal area image,which has a certain practical reference value.
