Delineating road accident risk along mountain roads

摘要

Purpose–The purpose of this paper is to attempt to put forth an innovative geographic information system (GIS)-based methodology for demarcating stretches of mountain roads with differential probability of road accidents. The proposed methodology has been tested in a sample road network of Uttarkashi district in Uttaranchal (India) and exhibits potential of reducing the frequency of road accidents by adopting suitable site-specific measures along accident-prone stretches.
