GIS-based air pollution distribution mapping of emissions from public buses for Coimbatore Corporation, Tamil Nadu, India

Abstract

Vehicle transport on roads is a dominant source of air pollution, and hence spatial assessment of its risks is necessary for the decision makers to evaluate its impact on the public. Indian road transport, especially buses, contribute significantly to air pollution, that too in highly accessible areas like bus stands and bus stops. This paper proposes a three-step integrated method to map relative pollution levels of bus stops and bus routes of Coimbatore Corporation using spatial analysis tools of ArcGIS and suggestion of routes for eco-friendly buses and vehicles.
