Road safety is a key issue and has a considerably important consideration worldwide. Road accidents have caused serious economic and social hazards. Therefore, analyzing alignment consistency can significantly improve its safety per-formance. This paper aims to briefly review the effect of the alignment elements on road safety from previous studies. It is including to explain the statistical models used to evaluate the impact of road alignment on road safety. The important findings found that Linear regression and Poisson regression were commonly used in pre-vious studies to disclose the effect of independent variables on road safety. Mean-while, Negative Binomial Regression was commonly used to high light the relation between horizontal alignment and accident rate. The results from the statistical models also can be concluded that by improving the road alignment it is possible to the road accidents.
