The automobile accident has grown to be a global issue in recent years, ranking as the ninth leading cause of mortality worldwide. The enormous number of traffic accidents that occur each year has made it a serious issue. Consequently, a comprehensive analysis is needed to tackle this overwhelming scenario. There are 33 lakh kilometers of roads in Bihar, and of those, over 65% of freight traffic and 80% of passenger traffic occur on the networks. Although making up only 1.7% of the total road network, national highways handle 40% of all traffic. Over the course of the last five years, the number of automobiles has increased at a regular rate of 10.16% per year. A road safety audit is a systematic process used to evaluate the likelihood of accidents and safety performance when developing new road plans, enhancing current ones, and maintaining existing ones. The two primary approaches in road safety are accident reduction and accident prevention. The roadway includes several conflict points, including settlements and industries, and carries a sizable amount of traffic throughout the day. A thorough examination of the NH will be conducted, focusing on safety and geometric design elements. The purpose of this article is to pinpoint shortcomings, enhance the design elements, and raise the road's trustworthiness.
