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

“…The main design criteria are the speed of the plan and the class of road users. In addition, everything related to the geometric design of the road is contained in this circular, such as the determination of corridors, visibility, the cross-section of the road, and drainage (Kriswardhana, Hasanuddin, & Palestine, 2020).…”

Horizontal alignment is included in the aspect of the geometric design of the road. Jalan Babat – Tapen in Jombang, East Java, is planned to have three horizontal alignments. This design aims to connect Jalan Babat and Jalan Tapen to shorten the travel time for the surrounding community's needs. This research uses the Bina Marga method, which refers to the Highway Design Standard of Indonesia 2021. First, road traffic data is obtained from the google earth application. The global mapper is then processed in AutoCAD to determine the coordinates of the road trace and the location of horizontal alignment. Then the data obtained is processed by referring to the Bina Marga method to design horizontal alignment. Jalan Tapen – Babat is a Secondary SJJ (Urban Road), Secondary Collector, and medium road, and the minor type of road 2/2 is not separate (TT). It has a flat terrain in design with a planned speed of 40 km / h. Three horizontal alignments with Spiral-Circle-Spiral (SCS) type, the first horizontal alignment is at STA 0+700 – 0+864, the second horizontal alignment is at STA 1+383 – 1+558, and the third horizontal alignment is at STA 2+132 – 2+304.

“…The relationship between geometric elements of road and road accidents has been developed to quantify [21][22][23][24][25][26]. Assessment using linear regression models showed unsatisfactory results as the properties of linear regression are normally distributed [27,28], which can generate negative or non-discrete values of accident rates [21].…”

“…The elements of geometric design play a big role to affect of the traffic accidents rates [21][22][23][24][25][26]. In Indonesia, research and assessment of road geometric was conducted in several cities, such as at Sungai Raya Kepulauan, West Borneo [32], at Magelang, Central Java [33], at Malang, East Java [34], at Tawangmangu, Central Java [35], at Luragung-Cidahu, West Java [36], and on the southern Java ring road [37].…”

Road traffic safety in developing countries is a complex problem involving many factors such as humans, vehicles, structures, and the roads' environments. This study focuses on reducing traffic accidents for passenger busses, aiming to identify the causes and create a simple computer model to warn in areas like EWS using geometric road data. The survey was conducted at accident-prone locations and simulated the travel speed, road geometric, and traffic composition data. Results can be concluded that the rate is largely influenced by the radius of curvature, visibility, road gradient, and weather conditions. The concept of the EWS computer model was developed using web-based technology that can use to record the data instantly. The model had tested in another location to validate the field parameter and geometric road improvement.
