ABSTRACT

Evaluating spatial inequalities using a single walking accessibility measure is quite challenging. In response, the paper proposes combining two accessibility measures (real and potential) to provide additional insights into the identification and mapping of spatial inequalities. The municipality of Getafe in the Madrid Metropolitan Area, Spain serves as a case study. A questionnaire, administered via face-to-face interviews, recorded the resident’s walking preferences for reaching in-store retail. A gravity-based model was used to calculate real and potential accessibilities, which were combined to map four accessibility places that originate spatial inequalities: advantageous, moderately advantageous, moderately disadvantageous, and disadvantageous. The results suggest that potential accessibility values are higher than real accessibility values, and the final map shows the city centre residents (mostly seniors) benefit from the advantageous accessibility places. Disadvantageous places are mainly found in the city’s periphery, where younger people live.

摘要

使用单一的步行可达性措施评估空间不平等非常具有挑战性。作为回应，本文建议结合两种可达性措施（真实的和潜在的），以提供对空间不平等的识别和映射的额外见解。西班牙马德里都市区的赫塔菲市就是一个案例研究。通过面对面访谈进行的问卷调查记录了居民前往店内零售店的步行偏好。基于重力的模型用于计算真实和潜在的可达性，这些模型结合起来绘制了导致空间不平等的四个可达性地点：有利、中等有利、中等不利和不利。结果表明，潜在可达性值高于实际可达性值，最后的地图显示市中心居民（主要是老年人）受益于有利的无障碍场所。不利的地方主要集中在城市的外围，那里是年轻人居住的地方。
