The Study has been undertaken because Road safety is an issue of major importance in all countries. Studies focused on geometric design and safety focuses on the improvement of highway design and to eliminate hazardous locations. The relationship between accident rates and geometric design elements is complex and not fully understood. Relatively little information is available on relationships regarding this. In this paper, road geometric design elements and characteristics are taken into consideration, and explanations are given on which extent they affect highway safety. Although it's been clearly shown that geometric elements like very short sight distances or sharp horizontal curve leads to a considerably higher accident rates which certain combinations of elements causes severe accident problem. It compares the results of studies in several countries and summarizes current international knowledge of relationship between safety and therefore the principal non-intersection geometric design parameters. These relationships between road geometric design and safety are studied through results made in different countries. In general, there's broad international agreement on these relationships.
