Explore Important Variables Influence the Safety and Accessibility of Sidewalk Using the Structural Equation Model (SEM)

Abstract

The prevalence rate of sidewalk was currently one of an important index to assess the development on various international countries. However, according to the result of The Annual National Safe and Accessible Sidewalk Assessment project on urban roads that conducted in recent year by the Construction and Planning Agency, Ministry of Interior; the suitability of sidewalk setting still has many issues for improvement. This study focused on the current condition of urban sidewalk environment, and conduct analysis by utilizing the Structural Equation Model (SEM) to explore important variables that influenced on the suitability of sidewalk. According to the analyzed result of the SEM, the width and clearance height of sidewalk were important factors that influenced on suitability of overall sidewalk. Therefore, from the result, improvement on sidewalk should improve the width and clearance height in priority.
