“…The issue of traffic incidents is a growing phenomenon in developing countries, such as Indonesia. Indonesia is ranked first, with an accidental death rate of 2.46% of total deaths [4]. From 2014 to 2018, the frequency of road accidents in Indonesia climbed by 3.30% every year [5].…”

Motorcycle accidents in East Java are more common than accidents in other modes of transportation. In addition to the many motorcycle users today, human, environmental, and road factors are considered the highest causes of these accidents. The study's goal is to find the best model of the Generalized Poisson Family Distribution (GPR), namely Lagrangian Poisson Regression (LPR) and to construct a model that will quantify the frequency of motorcycle accidents in East Java. Akaike Information Criterion (AIC) and Schwarz Bayesian Criterion (SBC) criteria are the model comparison methods used in this research. The selection was also made based on the model's exponential coefficient with a 95% CI to further deepen the selection results obtained. In addition, the paired samples test was performed to determine the degree of dissimilarity between the outcomes produced by the developed model and the actual data. The best performance model is applied to identify the characteristics or factors highly involved in motorcycle accidents. The research uses secondary data from related agencies, namely the East Java Regional Police, especially the traffic accident unit, and East Java BPS, for 38 cities and districts in 2021. The numerical optimization method used is the iteratively reweighted least squares (IRLS) algorithm, assisted by R Studio software. The study findings show that LPR is the most efficient and exact approach for modeling the frequency of motorcycle accidents. Meanwhile, the percentage of teenagers (X1), the frequency of motorized vehicles (X3), and the average annual rainfall (X5) have a considerable impact on accident occurrence. This research has an important contribution, especially in the field of transportation modeling and designing appropriate strategies to reduce the frequency of motorcycle accidents.

“…Then, an excellent geometric design for this road is also needed to accommodate people's needs in reaching educational institutions near this road with safe, comfortable, and environmentally sound, guaranteeing safety aspect. The role of geometric design is very crucial because one way to improve the safety aspect of the road is to improve the geometric design to reduce the occurrence and severity of road accidents [9]; [10].…”

Infrastructures, especially those directly related to the transportation system and has a crucial role in society is the road. “Jalan Leumah Neundeut” is a road transportation infrastructure in Sukawarna Village, Sukajadi District, Bandung City, West Java, Indonesia. It has the potential for trip attraction because it very close to the education area and passed by public transportation. This paper’s problem formulation arises based on the need for a well-road transportation infrastructure on “Jalan Leumah Neundeut”. It will be geometrically redesigned in its horizontal alignment to be as ideal as possible to fit the design criteria using AutoCAD® Civil 3D because it does not meet the design criteria, especially regarding the road spaces and lane configuration. The geometric redesign of the “Jalan Leumah Neundeut” horizontal alignment resulted in 450 meters of the total road length, 7 meters of carriageway width with 2/2 UD (undivided with two lanes and two ways) type, 60 km/hour of velocity design, S-C-S type of road curve, 47 meters of LS value, 130 meters of curve design radius, 2% of normal super-elevation, and 8% of maximum super-elevation. With the results obtained, Jalan Leumah Neundeut can maximize its potential.
