SPATIAL WALKABILITY INDEX (SWI) OF PEDESTRIAN ACCESS TO RAIL TRANSIT STATION IN KUALA LUMPUR CITY CENTER

Abstract

Walkability is crucial for sustainable transportation in cities but measuring it may be difficult due to unclear criteria that could be used as well as the methods available. This study aims to measure the Spatial Walkability Index (SWI) of pedestrian access to rail transit stations in Kuala Lumpur City Center by using a comprehensive set of criteria including Connectivity, Land use mix, Comfort, Security, and Safety, which are all represented as ground measurable parameters in this study. SWI was derived using Analytical Network Process (ANP) and GIS analysis. ANP is a decision-making technique that uses pairwise comparison to derive the weightage of the ground measurable parameters which then were used to determine the SWI for pedestrians by using GIS proximity analysis. In this analysis, the weightage of parameters located on the road were used as basis in deriving the SWI. As a result, the SWI for pedestrian access to rail-transit stations in KL City Center was determined. The results revealed that the SWI for most of the area was in average level. Based on analysis conducted, the SWI was greatly influenced by its criteria, proving how ANP can aid in analyzing the SWI by incorporating the weightage of its criteria.
