Sparking off walkability: A computational approach of urban network analysis on walkability in TOD neighborhoods

Abstract

Existing and proposed Transit Oriented Development (TOD) neighborhoods of Waipahu Transit Center Station in Honolulu, Hawaii are revisited by a proposed computational approach of Urban Network Analysis (UNA). The four measures of UNA: reach, gravity, closeness, and straightness are employed for investigating walkability in these given urban neighborhoods. In each measure, 1) accessibility to transportation 2) intersections frequency, 3) residential building density, 4) commercial building density, and 5) Industrial buildings density are delineated and proposed as vital factors for improving planning and design decisions on walkability patterns around the TOD neighborhoods.
