Abstract

India is a large country, and highways are essential to the nation's progress. National highways have a total distance of 70,548 km, cover 2% of India's total road network, and handle 40% of total traffic. The number of vehicles on the road is increasing as the population rises. As the number of vehicles increases, the number of accidents also increases. So, they have to be safe against accidents. The cause for the accidents is generated from the accident information on the GIS platform and redesigning the highway geometrics for mitigating accidents by proposing long-term measures such as vehicular underpass (VUP). Overspeeding is found to be a major reason for accidents and human negligence at junctions and intersections, and structural widening is proposed where the carriageway is lesser than IRC standards. Finally, the obtained improvements and the existing spots are simulated using PTV Vissim (student). As per studies and investigations on National Highway 75 total of 13 black spots were identified throughout the study area of 84.09 km. Five locations are identified where VUP is proposed as per IRC guidelines. National Highway is thus to be engineered considering all these inputs related to safety and design standards.
