Abstract
Road safety is a major issue and a significant global concern. Road accidents have created severe economic and social risks. The analysis can therefore significantly improve the safety performance of the alignment consistency. This paper aims to review briefly the effect of the alignment elements from previous studies on road safety. It includes an explanation of the statistical models used to review the impact of road alignment on accident of roads. Two regression models; linear regression and Poisson regression have commonly developed in previous studies to reveal the effect of independent variables on road safety. Negative Binomial Regression has, meanwhile, been commonly used to highlight the relationship between horizontal alignment and the rate of accidents. The results of the statistical models can also be concluded that road accidents can be reduced by improving road alignment.
