Behavioural Causes and Categories of Traffic Violations by Motorcyclists in Indonesian Urban Roads

Abstract

To prevent road accidents and formulate policies to promote road safety in urban roads, it is crucial to understand factors that cause violation of traffic rules. Although such issues have been investigated in developed countries, the availability of such knowledge in rapidly motorizing countries, such as Indonesia, is still poor. This study aims to investigate the factors influencing violation behavior by motorcyclists and types of such violations. The study is based on surveys of three metropolitan cities, namely Bandung, Yogyakarta, and Surabaya, in Indonesia. Structural equation modelling has been performed to investigate factors influencing motorcyclists to commit traffic violations and their causal relationships. Although there are differences in the ranking of factors influencing traffic violations among the three cities studied, the analysis has been able to show patterns of similarities as well. The inadequacy of engineering and maintenance conditions of the road infrastructure appears to be partly responsible for the phenomenon of motorcyclists developing a lack of respect to traffic rules.
