Road geometric design is part of highway engineering where it deals with the positioning of the physical elements of the roadway according to standards and constraints. The fundamental objective of geometric design is to produce a smooth- flowing and safe highway facility. A curved road segment is one of the major components of road geometric design. However, due to its alignment characteristics, this area is prone to fatal traffic crashes compared to other road alignments. A study done in other countries revealed that curve roads had a greater risk of having fatal crashes as compared to straight roads. In Malaysia, fatal crashes on curved segments accounted for 16% of the total number of traffic crashes in 2015. Although many crashes were recorded at straight roads with more than 10,000 incidents in 2015, the proportion of curve fatal crashes to total curve crashes is 47% while the straight fatal crashes to total straight crashes is 43%. Thus, this study was established to investigate the contributing factors to crashes at the curved road in Malaysia. Most crashes that occur at curved road sections are at Negeri Sembilan and Perak. Therefore, Negeri Sembilan has been chosen as a case study for this research. A total of 46 sections of curved road in Negeri Sembilan were chosen as a study location. The study has been divided into two categories; accident-prone area and non-accident area. The roadway characteristics that have been investigated are the type of curve, the radius of the curve, lane width, curve length, super elevation of the curve, speed approaching curve, median type, availability of roadside barrier, road marking, and availability of lighting and signage. The findings of the study concluded that number of lanes and pavement road marking are the underlying factors to crashes at curve roads. This result is in agreement with several studies, which highlighted the importance of visibility at curve roads and the driver behaviour of changing lane and speed when there are given more space, which may lead to skidding or loss of control.
