The transportation field is one of the challenging fields. It plays a vital role in the development of any region. Policymakers and transport planners are trying to make the transportation field more sustainable. Sustainable transportation indicators help to evaluate transportation systems. Public transportation is the key component of sustainable transportation systems. As accessibility is a major transportation indicator, it is used in the study to evaluate the sustainability achievement of the study area. Public Transportation Accessibility Level (PTAL) methodology is an effective tool used to evaluate the accessibility of public transportation in an area. Accessibility index values identified using the methodology can be used to evaluate accessibility. Accessibility analysis using GIS techniques is adopted in the study. Mapping of accessibility indices in ArcGIS gives an appropriate visualization to analyze public transportation accessibility. The low accessible area to public transportation can be easily identified from the analysis. This study includes the application of PTAL methodology incorporating the GIS software to analyze the accessibility of public transportation.
