长沙交通网络空间分布调查与研究——以芙蓉中路“道路血栓”为例

长沙市城市道路交通量空间分布呈现中心区高负荷，依次向外围递减，过江交通高负荷，并以橘子洲大桥和银盆岭大桥为中心沿湘江向南北依次递减。芙蓉路作为市区惟一贯通的纵向主干道，集过境、进出及内部集散等多种功能于一体。本文针对芙蓉中路的交通状况展开全面的调查，试图找出造成芙蓉中路拥堵不畅的关键因素，即诊断出芙蓉中路“道路血栓”的形成原因。

Investigation and Research of Changsha Transportation Network Spatial distribution - to traffic congestion of Furong Middle Road as an example

The space distribution of vehicle trattlC loao on the Changsha urban roads is characterized by high load in the central area, decreasing progressively towards the city outskirts, high river-crossing traffic load concentrating on Juzizhou Bridge and Yinpenling Bridge while decreasing progressively along the Xiangjiang River to the south and the north. As the only urban main road running lengthways, Furong Road integrates various functions such as transit, getting in and out of the city, and internal gathering and distribution. Through overall investigation of Furong Middle Road traffic condition, the article attempts to find out the critical factors leading to traffic congestion of Furong Middle Road.
