Spatial Correlation Between Redundancy of Route Options and Commercial Facility Locations in Station Front Areas
Year: 2025
Type: article
Abstract: This study evaluates the effectiveness of a redundancy-based index (RI), originally developed for disaster planning, as a spatial metric in urban analysis. By capturing the degree of overlap among multiple feasible paths, RI serves as a basic and quantifiable tool for assessing route diversity. Focusing on pedestrian networks around major stations, we demonstrate that areas with higher RI values—indicating greater differentiation of paths—exhibit stronger clustering of restaurants. These findings support the use of RI as a foundational indicator of spatial diversity and contribute to a deeper understanding of urban vitality in the context of planning.
