Abstract
Segregating motorcyclists is one of the practices used to reduce motorcycle collisions with other road users. This study examined the relationship of motorcyclists’ psychology and their risky behaviours at these different types of motorcycle lanes. The risky behaviours were focused on their speeding and not wearing wear a helmet. The psychological determinants measured in this study were the desire to speed, attitude, perceived behavioral control, moral obligation, perception of danger, fear of being caught, and perception of others’ behaviours. Structural equation modeling (SEM) within LISREL was used to model speeding and neglecting helmet. The results show that the tendency to speed was stronger in exclusive motorcycle lanes, whereas neglecting to wear a helmet was most commonly occurred on paved shoulders. Regarding the psychological factors, motorcyclists’ perceived behaviours of others showed the strongest relationship toward both risky behaviours.
