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.
