针对大部分城市公交发展滞后、公交站点和公交线路供需不平衡等问题,该文采用统计数据与实调数据相结合的方式,利用两步移动搜索法,从供需的角度研究分析城区公交站点服务的空间可达性。以河南省焦作市为例,以城区街道办为基本研究单元,分别采用固定阈值的简单两步移动搜索法和基于实测数据拟合的增强两步移动搜索法,对焦作市公交设施可达性的空间布局和差异性进行研究。实验结果表明:焦作市城区公交站点服务可达性整体上比较差;城区公共交通资源发展不平衡,空间差异比较明显,公交站点供需相对平衡区域主要集中在城区中心城区,低值区主要集中在城区边缘;增强两步移动搜索法考虑了距离衰减对人们公交出行的影响,更能反映焦作市真实的公交状况。
In view of the lagging development of public transport in most cities and the imbalance of supply and demand between bus stations and bus lines, this paper uses the two-step mobile search method combining statistical data with real data to study and analyze the service of urban bus stations Space accessibility. Taking Jiaozuo City of Henan Province as an example, the urban street office was taken as the basic unit of study. The fixed two-step mobile search method with fixed threshold and the enhanced two-step mobile search method based on measured data fitting were used respectively. The spatial layout and the differences are studied. The experimental results show that the accessibility of bus stations in urban areas of Jiaozuo City is relatively poor overall; the development of urban public transport resources is unbalanced with obvious spatial differences; the relative balance between supply and demand of bus stops mainly concentrates in downtown urban areas; Urban fringe; enhanced two-step mobile search method to consider the impact of distance attenuation on people’s bus travel, but also to reflect the real Jiaozuo City bus status.
