In Indonesia, with high railway use, many of the rail infrastructures intersect with roads in the form of active and passive crossings. Several measures had been put to ensure safety on railway crossings, which are the use of flashlights, sirens, and gates. However, there were still violating behaviors of road users that cause accidents on railway crossings. The study of road users’ behavior at railway crossings had been conducted in numerous countries. However, the study of road users’ intention on violating railway crossings in Indonesia is still limited, especially for motorcyclists. The motorcycle is the highest transport mode used in Indonesia, which took 80% of total vehicle ownership. Hence, underlying factors that might influence motorcyclists’ intention on violating railway crossings need to be further studied. In this study, several factors were elaborated, which consist of demographical factors, environmental factors, and the use of The Theory of Planned Behavior to explain risky crossing behavior. The findings in this study would be used as a reference for further study.
