Abstract The development of the nation’s states is said to be mostly facilitated by national highways and expressways. Because of the enormous cost associated with them, road traffic accidents have been identified as one of the unfavourable factors that contribute to the stifling of economic progress in developing countries. This raises social and economic concerns. The number of automobiles on the road increases in parallel with global population growth. Accident rates go up in direct correlation to the increase in the number of vehicles on the road. Therefore, there must be a decrease in accidents to demonstrate the safety of roadways. Subjective factors and objective aspects can be used to categorize accident causes. While objective factors include things like road conditions, road geometry, and other engineering-related elements, subjective issues mostly refer to the psychological issues of drivers and pedestrians on roads. The study of unintentional black spots focuses on the study of road safety because the two are interwoven, and if road safety is addressed, the likelihood of accidents is lowered. Therefore, it is essential to identify “black spots” and make modifications to the specific places in terms of road geometry. The primary objective of this study is to deliver a strategy along with complete investigations for the evaluation of black spots and their remediation. Thus, it is needed to take into account all of these design and safety-related considerations when engineering Indian National Highways. These factors were taken into account in a comprehensive study that presented the reality of accidents happening on various Indian roadways, along with their causes and solutions.
