Relative accessibility is a widely studied approach that recognizes access to major locations as subjective and shaped by individual circumstances (e.g., individual preferences, habits, and cultural norms). One missing element in the knowledge base is how relative accessibility can be effectively mapped for decision-making. To fill the research gap, this paper evaluates whether cartograms are an appropriate tool for mapping relative accessibility, taking the city of Zaragoza, Spain as a case study. The research design included three phases: (i) elaboration of grid-based maps on relative non-motorized accessibility; (ii) elaboration of cartograms on relative non-motorized accessibility; (iii) an end-user evaluation with 30 local practitioners to analyze the effectiveness of cartograms to map relative accessibility compared to grid-based maps. Participants signaled that diffusion-based cartograms could be complementary to grid-based maps, providing better visualization of spatial dissimilarity patterns of accessibility between population groups. However, participants noted greater difficulty in identifying Dorling cartograms as an effective technique for mapping relative accessibility. The paper closes with a review of the strengths and weaknesses of the potential application of these visualization techniques in the field of accessibility planning.

相对可及性是一种经过广泛研究的方法，可将对主要地点的访问视为主观因素，并受个人情况（例如，个人偏好，习惯和文化规范）的影响。知识库中缺少的一个要素是如何有效地映射相对可访问性以进行决策。为了填补研究空白​​，本文以西班牙萨拉戈萨市为例，评估了制图是否是映射相对可及性的合适工具。研究设计包括三个阶段：（i）制定相对非机动可及性的基于网格的地图；（ii）制定关于相对非机动可达性的制图；（iii）与30位当地从业人员进行的最终用户评估，以分析制图相对于基于网格的地图的相对可及性。与会者表示，基于扩散的制图可以补充基于网格的地图，从而更好地可视化人口群体之间可及性的空间差异模式。但是，与会人员指出，将多林制图确定为映射相对可及性的有效技术难度更大。本文在结尾处回顾了这些可视化技术在可访问性计划领域中的潜在优势和劣势。
