摘　　要： 基于机会模型、潜能模型和Allen网络可达性模型,客观评价公交车站所在节点乘客以公交系统为载体的空间可达性,提出可达性是可达数量和可达质量的复合,可达质量包括可达质量系数与可达性贡献率.分析影响可达质量的主要因素,构建公交车站可达性度量模型.研究结果表明,公交线路的数量、发车频率对所停靠公交车站的可达性影响显著,不同公交车站的可达性存在明显差异. In order to evaluate the spatial accessibility of bus travel for a specific urban node more comprehensive-ly and more objectively, based on the research results of Opportunity-based Model, Potential Model and Allen＇s Network Accessibility Model, a new view is presented that accessibility is the multiplier of accessibility quantity and accessibility quality while accessibility quality is composed of accessibility quality efficiency and accessibility contribution rate. Then, through analyzing the main influence factors of accessibility quality, an accessibility measurement model is established in which accessibility of bus stop is determined by both accessibility quantity and accessibility quality. Results show that accessibility is significantly affected by the quantity and departure fre-quency of bus lines, and obvious differences exist among diverse bus stops. The conclusions of empirical study can be applied in public transit network optimization and bus stop distribution.
