摘要
"1小时交通圈"是近年来区域交通建设和经济发展领域较热门的概念,在主要中心城市周边,很多城镇都提出了融入其1小时交通圈的战略规划。通过对交通圈进行分类,界定了研究要素,以长三角地区公路和铁路为道路网络数据集,定量研究了上海市城际1小时交通圈道路的设计方法、建立方法和构面方法。根据交通规划预测了2020年交通圈的扩散范围,并分析了上海市主城区对外1小时交通圈的性质及内部结构,根据不同交通工具的速度和特征将交通圈分成商务圈、大众圈、货运圈和高铁圈等类型,最终总结出交通圈发育结构。研究结果表明:①2011年,上海市1小时交通圈可以覆盖到周边10个地市的部分区域,并随着交通设施的完善不断接近"圈层-环点"交通圈结构。②通过分析1小时交通圈中的"岛",能够了解到路网完善程度和存在的问题,辅助道路规划。③对交通圈进行分层研究能够更好地通过交通圈对圈内的人流和物流进行分析。④"圈层-环点"状的现代中心城市城际交通圈结构能够检验中心城市周边路网建设所处的阶段,以及为城市、区域等相关领域的经济圈、都市圈研究打下交通基础。
＂One hour traffic circle＂ is a popular concept in regional traffic construction and economic develop-ment. Recent years, many cities and towns have put forward strategic planning to get into one hour traffic cir-cle of the regional center city around them. In this paper, the concept of traffic circle is classified firstly, then, the research elements are defined, based on the highway and railway network dataset in Yangtze River Delta, the design method, construction method and structure method for one hour traffic circle of Shanghai city are quantitatively studied. And on the basis of these methods and data, one hour traffic circle of Shanghai city in the end of 2011 is calculated. According to the traffic planning to 2020, the diffusion area of traffic circle is pre- dicted, and the properties and internal structure of one hour traffic circle of the main in Shanghai are analyzed. Then, the traffic circle is divided into business circle, public circle, freight circle, and high speed railway circle according to the different vehicle speed and characteristics. Finally, the traffic circle model is summarized. The results show that： 1, in the end of 2011, one hour traffic circle of Shanghai City can cover part of the around 10 cities, and with the improvement of transportation facilities, the circle will be more and more close to the ＂cir-cle ＆ surrounding point model＂. 2, the degree of perfection and existing problems of road nets can be defected through analyzing the＂ islands＂ in a traffic circle, which can assist road planning. 3, through classification of the traffic circle, people flow and material flow in the circle can be analyzed better. 4, Circle ＆ surrounding point structure can inspect the period of road network construction around center city, and provide basis for studying economic circle, and metropolitan area in city and regional science.
