Analysis of Fatal-Serious Accidents and Dangerous Vehicle Movements at Access Points on Malaysian Rural Federal Roads

Abstract

This paper analyzed the factors relevant to fatal and serious accidents on rural federal roads in Malaysia. The objective is to identify the dangerous vehicle movements and factors significant to fatal-serious accidents at access points (non-signalized minor junctions) and to suggest countermeasures. This research carried out numerous surveys to observe various traffic movements including right and left turns, from minor or major roads, and other characteristics, to construct accident analysis models. One of the findings was that right-turn motorcycles caused serious conflicts and were the most dangerous movement. Based on this finding, this paper examined the driver behavior of gap acceptance and serious conflicts using our proposed four gap patterns for a right-turn vehicle from minor to major roads at an access point. Further analysis was performed to identify the gap pattern and factors relevant to the serious conflicts. The results demonstrate that right-turn vehicles, especially motorcycles, apparently intend to start turning right in a very short gap and the approaching speed and the gap between a pair of vehicles from different directions in the mainstream are the critical factors causing serious conflicts to the right-turn vehicles.

Structural Equation Modeling of Right-Turn Motorists at Unsignalized Intersections: Road Safety Perspectives

“…Once the recording finished, all the video cams were brought to the laboratory for further microscope analysis. The selection of an unsignalized intersection (UI) was based on two aspects: first, the accident's blackspot ranking recorded (Fajaruddin et al, 2021), and second, the road safety facilities provided on that UI. UI 2 was a three-leg unsignalized junction.…”

“…By using regression and logistic regression approach, (Fajaruddin. Fujita, and Wisetjindawat, 2013) analyzed accident causality and traffic behavior at black spot locations on Malaysia Federal Route.…”

“…The study revealed that the most unsafe turning maneuver is the movement of a right-turning motorcycle from a minor to a major road and a left-turning motorcycle from a minor road. (Fajaruddin et al, 2021) have developed rider and passenger car models by applying binary regression. However, it does not concentrate on traffic volume, turning behavior, and implementation of structural equation modeling.…”

“…However, it does not concentrate on traffic volume, turning behavior, and implementation of structural equation modeling. (Fajaruddin et al, 2021: Fajaruddin. Fujita, andWisetjindawat, 2013), have established for the right-turning motorist and clearly described a gap sequence at unsignalized intersections.…”
