Malaysia has a worrying road fatality rate compared to many other countries, and the high number of registered motorcycles (vulnerable road users) in the country is one of its most distinctive characteristics. However there has previously been limited experimental research on driving conducted in Malaysia. This thesis aimed to investigate Malaysian drivers’ ability to perceive other road users (cars and motorcycles) and how they make judgments about the safety of pulling out at junctions. Malaysian drivers’ performance in these tasks was compared with UK drivers (Chapter Two). Various studies were also conducted to investigate how different factors affect drivers’ perception and judgment, such as time of day and use of headlights (Chapter Three), a honking sound (Chapter Four), motion and speed (Chapter Five). Chapter Six went on to investigate drivers’ ability to judge the intention of other road users. This series of experiments has provided new insights about the perception and judgment of Malaysian drivers. Possibly due to the higher exposure to motorcycles, Malaysians have a better ability to detect approaching motorcycles than UK drivers though they are also more likely to judge that it was safe to pull out at junctions. In addition, the number of incorrect judgments made by Malaysian drivers about the safety of pulling out is a concern especially where a collision would happen based on the decision. Moreover, switching on headlights increased drivers’ ability to perceive other vehicles during night time but not necessarily during day time. However, switching on headlights decreased the likelihood of drivers judging that it was safe to pull out in front of motorcycles regardless of time of day. The results also suggested that a honking sound did not facilitate the ability to perceive other vehicles, but did decrease drivers’ tendency to judge that it was safe to pull out. Lastly, it was shown that it is important to provide reliable signals in order to improve road safety. In dynamic video stimuli, signalling is more informative for judging the intention of approaching cars than motorcycles, which could lead to poor judgment making about approaching motorcycles at junctions.
