ASSESSING POTENTIALLY WALKABLE HERITAGE TRAIL IN JOHOR BAHRU, MALAYSIA USING ANALYTICAL HIERARCHICAL PROCESS AND GEOGRAPHICAL INFORMATION SYSTEM

This study aims to assess walkability on potential heritage trails in Johor Bahru City using AHP and GIS. In this study, MCDA was used to determine the weightage of the criteria used by GIS to assess the potentially walkable heritage trail in Johor Bahru City. Past studies have been used as a reference to determine the criteria for potentially walkable heritage trails. The criteria are all measurable and can be represented as spatial data on the ground to be used in GIS analysis. Then, the weightage was calculated using the Analytical Hierarchy Process (AHP), which is one of the MCDA weighing methods. The weightages were then used in Travelling Salesman Problem (TSP) Analysis to assess the potentially walkable heritage trail. Weightages are added as a cost during TSP analysis by calculating their value in a field script. The script includes the cost and each criteria name for a better understanding of the TSP process. A single heritage trail was produced that connects six different heritage locations while prioritizing criteria in this study when creating the heritage trail. The six heritage locations are the Royal Abu Bakar Museum, Johor Bahru Chinese Heritage Museum, Bangunan Sultan Ibrahim, Johor Ancient Temple, Masjid Al-Attas and Arulmigu Sri Rajakaliamman Glass Temple. The heritage trail has improved in its accessibility and travel time compared to the existing path. This indicates that travelling using potentially walkable heritage trails produced by this study will shorten travel time and be healthier as it focuses on walking rather than passive transportation.
