Abstract
The study deals with road safety, crash hot-spot, and crash cold-spot identification on a rural national highway NH-48 in Maharashtra, India. Crash data from 2016 to 2020 of the NH-48 is considered for this study. There are three separate scenarios: 2016–2018 as scenario-1, 2017–2019 as scenario-2, and 2018–2020 as scenario-3, for which the crash hot-spots and crash-cold spots are identified. The comparison and analysis of crash hot-spots and crash cold-spots identified over the three scenarios are presented to understand the major hot-spots. It was observed that in all 3 scenarios, the chainage wise sections 592.24 km–611.5 km, and 712 km–725 km are performing excellent as cold-spots, since they do not have any hot-spots in between them. Whereas, the sections 611.5 km–629 km, and 679.5 km–707 km have 0 cold-spots in scenario-2, and scenario-3. The fall in the number of crash hot-spots every year in all three scenarios is 49.68 % in scenario 2 and 20.25 % in scenario 3. The rise in the number of crash cold-spots every year in all three scenarios is 46.42 % in scenario 2 and 48.78 % in scenario 3. Overall, the rise in the crash cold-spots and the fall in the crash hot-spots indicate that the highway is performing well in achieving road safety.
