Research gaps in Walkability studies using the SLR approach

Abstract Walkability is currently a significant research topic because it influences health, social, and environmental aspects. However, there is very little research has been conducted to provide specific information about the research gap on that topic. Identifying research gaps before beginning research on a specific topic is critical for providing novelty. Therefore, identifying the existing research gaps in walkability and grouping them into a theme is the purpose of this study. A systematic literature review is applied. 101 articles from 2022 to 2023 are collected to present research gaps in the Walkability studies in recent years. Those data then are analyzed by using a simple affinity diagram to group the research gaps into themes. The review reveals the majority of papers focus on walkability factors and their relationships, including physical walkability factors, perceived walkability factors, walking behavior, physical activity, and social conditions. The findings of this study will aid researchers in architecture, urban planning, and urban design in more easily determining research gaps and providing a quick grasp of a comprehensive understanding of research gaps from the last two years over the world concerning walkability studies.
