Road geometry consists of horizontal and elevation components of road extensions, which mainly include tangent lines, arcs and connection curves. The role of these components in guiding the driver as well as his prior knowledge of the continuation of the road is very important. Also, the arrangement and combination of these components can have a positive or accidental effect on the safety and comfort of the driver. Horizontal curves are considered as one of the most accident-prone points of the road. Centrifugal force on vehicles and human error are the two main factors in the occurrence of accidents in these areas and will eventually lead to overturning or slipping of vehicles. In this study, the main goal is to find a way to increase safety and reduce the rate of accidents due to the relationship between human factors and road geometry. Which is mostly based on previous research and analysis. Studies on safety measures to increase safety in recent years have been collected and reviewed. The results show that the review of new methods, models and schemes such as risk reduction plan to support decisions, safety performance prediction methods on horizontal curves such as Safety Performance Function (SPF) in the future will help better performance for users. The road guarantees. Also, using short-term economic solutions such as route marking will increase safety. On the other hand, the most important criteria for assessing the safety of the vehicle when passing the corner is to estimate the resistance of the vehicle against frustration and overturning, which is also important.
