Malaysia is one of the developing countries that face the highest rates of road accidents in Asia. The most common accident happens between motorcyclist and cars. A motorcyclist is 17 times more dangerous than a passenger car. Analysis shows that the three main types of accidents in Malaysia are: collisions with passenger cars, collisions with other motorcycles, and single-motorcycle accidents. Road accident rates continue to rise in Malaysia, due to the lack of geometric design consistency on roads, wherein drivers make errors due to the geometric features of roads. Several prediction models are developed in this study for estimating operating speed on tangent sections, depending on the characteristics of the tangent, and on continuous speed profiles. Geometric factors such as access point, tangent length, curve length, shoulder width, and lane width influence operating speed profiles for the development of tangents and curves for motorcycle and cars. The study was conducted at F0050 of Johor federal roads. Furthermore, the continuous speed profile data were used to develop road design consistency profiles for cars and motorcycles (IC). The development of the consistency model is based on these parameters: the bounded area between the profile and the average speed and standard deviation of speed along a segment. The highest areas of an accident at km24, which are justified based on the design consistency of the area and on the integrated design consistency model between car and motorcycle, are of a poor design. The poorer the design consistency, the higher the potential for accidents. The study also shows that the model are well compare to the real accidents data of cars and motorcycles.
