Abstract

Urbanization rate is at its peak bringing economic boost as well complex issues related to it. In
recent past, many countries are now promoting and implementing urban sustainability to
overcome or reduce the complications with a major focus on promoting public transport
systems. United Nation Sustainable Development Goals 2-2030 (UNSDG’s 2030) provides a
path to countries worldwide in achieving the targets. Geographic Information System (GIS)
and Remote Sensing are considered to be extremely useful for urban sustainability. Landsat
satellite imagery was used to estimate area coverage of different classes. Different platforms
are available for remote sensing analysis from which the Google Earth Engine, a cloud based
platform was used for supervised classification using Random Forest classifier. A prediction
map for 2030 was generated to understand the trend of city expansion using MOLUSCE.
Detailed road network was created and service area analysis was performed for proposed bus
stops. Main objective of the study was to investigate the serviceability of the proposed public
bus transport system for 2030. For the prediction map, the results indicate that serviceability
for urban areas is 38% while the un served area is 62%.The study spatially identified the area
that appeared to be vulnerable to future city expansion. The results also recognized the
importance of the road network in urban expansion. By analyzing the outcome, it can be
concluded that the geospatial approach can be used in future planning for urban development
and sustainability.
