“…The previous researcher shows that delineating road along mountain roads indicates that there is a fairly high risk of accidents [16]. This research is in line with the opinion of Wilches, which states that geometric road design that is inconsistent and not under technical requirements will trigger a high accident rate [4].…”

The geometric design of the road should be based on the road design criteria and requirements contained in the design guidelines. However, the limitations of natural conditions and considerations during the design make the road design not ideal according to the guidelines. Deviations from the guidelines may indicate that the road is not standard and has potential accident risk. This study intends to analyze the risk of accidents from the geometric aspect of the road. The purpose of this study is to find out how the level of accident risk is due to the geometric conditions of the road. The approach used in this analysis is functional worthiness where each road component is compared with field data and design guidelines. The data collection method was carried out by measuring the geometric components of the road, which included horizontal and vertical alignments. The location of data collection was national roads in the Jambi Province area with a total road length of 1.095 km. For analysis purposes, the road data is divided into 82 segments. The analytical method used is multiple regression with various statistical parameters related to these results. The modeling results show that the regression coefficients for each variable horizontal alignment, vertical alignment, and combination of horizontal and vertical alignment are 0.248, 0.349, and 1.170, respectively. While the constant in this regression equation model is 3.366. The greatest value of the accident risk contribution is in the horizontal and vertical alignment variables with a coefficient of 1.170. The results of statistical tests show that the relationship between accident risk and the geometric aspect of the road has a strong linear relationship

“…Inconsistency of the geometric layout on the road accident rate can be a trigger for accidents. The research has been carried out in a mountainous area where the topography has a very dynamic combination of alignments [4]. Consistency with the design criteria is an effort that must be maximized so that road safety can be guaranteed [5].…”

“…Sehingga pada akhirnya dapat ditunjukkan bahwa geometrik design yang tidak konsisten dapat menjadi penyebab tingginya tingkat kecelakaan disamping penyebab-penyebab lain. Karakteristik geometrik rute jalan, memiliki hubungan yang erat antara ketidakkonsistenan rute geometrik dan terjadinya kecelakaan lalu lintas (Wilches et al, 2020). Dengan membentuk model yang lebih sesuai untuk kondisi geometrik jalan maka dapat diperoleh deskripsi yang lebih jelas.…”

Road infrastructure has an impact on the occurrence of road traffic accidents. The geometry of a road is a variable that influences the occurrence of road traffic accidents. Interpreting the observed crashes into an equation that can describe the crashes is one of the most difficult problems faced by scientists and engineers in any research. The traffic accident research conducted is still limited to analyzing the causes of accidents and jumping to handling strategies that do not reveal how much geometric influence on accidents at the location. This research was developed using a comprehensive modeling approach to illustrate how highway geometric design, in this case the alignment, influences crash rates. This study aims to analyze the influence of road geometrics on the incidence of accidents. The method used is multiple liner regression measurement model using R-Studio. The variables to be studied include road geometry planning parameters, especially horizontal alignments which include stopping sight distance (X1), radius of horizontal curve (X2), shoulder width X3, and transition curve length (X4). The results of the study obtained a relationship in the mathematical equation Y = 99.55508-0.02634X1+1.17647X2-0.06999X3-0.03906X4 with the most significant correlation value produced is the transition curve length and radius of horizontal curve. Based on the multiple R-squareed value of 0.8775 this model has a very strong correlation category. Where the ability of X1 to X4 is able to explain Y by 80%.
