基于慢行交通的长沙市老城区道路交通网络优化
|
摘要
老城区路网基于慢行交通设置,往往是慢行交通规划的热点,但依据缺乏,优化艰难。本文运用常规交通网络分析、空间句法和路径结构分析,将长沙市老城区与知名慢行交通中心城区进行对比,得出长沙市老城区道路交通网络存在交叉口X形率偏低、空间可达性较差、可识别性较差和路网连接度偏低等问题。基此,对长沙市老城区道路交通网络给出相应的优化建议。
The old urban road network based on slow traffic settings is often the focus of slow traffic planning, but lack of basis makes it difficult to optimize. By using the analysis of routine traffic network, spatial syntax and path structure, this paper compares the old urban area of Changsha with the well-known slow traffic central area, and concludes that there are some problems in the road traffic network of the old urban area of Changsha, such as low X-shaped rate of intersection, poor spatial accessibility, poor identifiability and low connectivity of road network. Based on this, the paper gives the corresponding optimization suggestions for the road traffic network in the old urban area of Changsha City.
