System and Human Errors in Vietnam Motorcycle Road Traffic: A Study Using the Extended Driving Behaviour Questionnaire (DBQ)

Accidents on the road are a global problem affecting public health and the economy. According to the World Health Organization (WHO), the number of people who are killed in traffic accidents around the world reaches 1.35 million per year, with more than 90 per cent of those deaths occurring in low- and middle-income nations, with one fatality for every 23 per cent of the population. Most people in Vietnam get around on motorcycles, which account for 95% of the country’s vehicle fleet and have the highest ownership rate per capita of any country in South-East Asia. This mode of transport contributes to a high proportion of road traffic collisions, accounting for about 60% of all road traffic accidents. The primary objective of the present study is to offer a thorough understanding of riding behaviours in Vietnam through the integration of the driving behaviour questionnaire (DBQ), which focuses on human errors, and the Traffic Climate Scale, which addresses system errors, to examine their association with risk-taking attitudes in relation to motorcycling. The study bears significant relevance for policymakers and traffic managers, as it offers valuable insights to help them design effective interventions to enhance motorcycle safety in Vietnam.
