城市公交可达性与网络空间结构关系分析——以焦作市为例

Analysis of the relationship between urban public transport accessibility and network spatial structure:Taking Jiaozuo City as an Example

针对城市公交系统的可达性及其网络空间结构的耦合关系,构建基于公交站点效率且融合Huff模型的3步移动搜索法,对焦作市居民的公交站点可达性进行研究,依据P-空间模型构建城市公交网络结构,利用耦合协调度模型分析居民的公交站点可达性与公交网络的协调状况。研究表明,焦作现有公交系统对不同区域居民提供的服务不均衡,对主城区投入的交通资源不充足,且忽略了偏远地区居民出行需求,研究结果可为焦作公交网络优化提供参考和建议。

Aiming at the coupling relationship between the accessibility of urban public transport system and its network spatial structure,a three-step floating catchment area method based on bus station efficiency and huff model is constructed to study the accessibility of public transport stations of residents’in Jiaozuo City.The urban public transport network structure is constructed according to the p-space model,and the coordination between residents'bus station accessibility and public transport network structure is analyzed by using the coupling coordination degree model.The interaction between the centrality of township streets and the accessibility of residential bus stations is at the upper-middle level,but the degree of benign coupling is at the lower-middle level,basically in a state of weak coordination and dissonance.The services provided by Jiaozuo’s existing public transport system to residents in different regions are unbalanced,the traffic resources invested in the main urban area are insufficient,and the travel needs of residents in remote areas are ignored.The research results can provide references and suggestions for the optimization of Jiaozuo public transport network.
