【摘要】 城市交通拥堵是制约城市发展的重大问题之一,而公交优先能够引导城市交通优化,近年来公交优先已成为国内大城市空间发展优化的策略之一。国内城市公交已具备相当规模,公交设施的空间布局也反映了城市结构特征。文章以郑州公交为例,基于ArcGIS软件中的核密度分析、可达性分析等分析方法对郑州公交设施的现状空间分布特征和可达性进行分析。并基于现状特征进行讨论,提出相应的布局优化建议。更多还原

【Abstract】 Urban traffic congestion is one of the essential challenges restricting urban development, while public transportation priority can guide urban traffic optimization. In recent years, public transportation priority has become one of the strategies for optimizing the spatial development of large cities in China. The domestic urban public transport has a considerable scale, and the spatial layout of public transport facilities also reflects the characteristics of urban structure. Firstly, taking Zhengzhou public transportation as an example, this paper analyzes the current spatial distribution characteristics and accessibility of Zhengzhou public transportation facilities based on the analysis methods of nuclear density analysis and accessibility analysis in ArcGIS software. Secondly, based on the current characteristics of the discussion, the corresponding layout optimization suggestions are put forward.更多还原
