    摘要:

    基于长三角一体化发展背景,以太仓市为例,研究组团城市快速通道分布体系。研究显示,与单中心城市相比,“组团式”城市的交通出行特征有显著差异性,主要以组团联系和组团内部交通为主,大流量廊道基本沿着组团OD(交通出行量)走向,但又存在中间大量的郊区段并伴随一定的潮汐交通现象。研究表明:组团城市建设快速路是完全可行的,快速路在选线上要以组团联系为主,形态上以服务大客运OD为主。另外快速路的末端可采用快捷路(或主干路)衔接,延伸快速路敷设范围,近期保证设施效益的最大化,远期也可进行快捷路快速化改造,实现城市快速路网络化布局的可能。

    Abstract:

    Based on the background of the integrated development of the Yangtze River Delta, taking Taicang City as an example, the fast-track distribution system of cluster cities is studied. Research shows that compared with the single-center cities, the traffic travel characteristics of cluster-type cities are significantly different. The cluster connections and intra-cluster traffic are the main features. The large-flow corridors basically follow the OD (origin destination) direction of the cluster, but there are a large number of suburb sections accompanied with certain tidal traffic phenomena in the middle. Studies have shown that it is completely feasible to construct the expressways in cluster cities. The route selection of expressways should take into account the group connection, and the main form is to serve the OD of large passenger transport. In addition, the end of the expressway can be connected with the express road (or trunk road) to extend the laying range of the express road, which can maximize the benefit of the facilities in the short term, and also quickly reconstruct the express road in the long term in order to realize the networked layout of the urban expressways.
