Abstract

This study was undertaken to examine the prevalence and contributing factors of turning indicator use by motorcyclists in mixed-traffic environments due to a lack of prior empirical studies. The method involved a cross-sectional research design and in-vehicle pre-recorded observations at four selected routes in Kuala Lumpur and Selangor, Malaysia. The data for each route were collected for five days during peak hours (mornings, afternoons and evenings), comprising four weekdays and one weekend day. A total of 3,963 related motorcycle movements were recorded and analyzed.In general, the turn signal activation rate among motorcyclists was 30.1%, which may be considered low. The highest turn signal neglects were recorded when motorcyclists entered the roundabout (80.2%) followed by lane-changing on the expressways (78.8%) and turning at the 3-legged signalized intersections (75.3%).Further multivariate logistic regression analyses conducted for both lane-changing and turning at intersections revealed several significant variables that influenced the use of turn signals among the motorcyclists, particularly riders who were female, carrying a pillion, performing right turns, and travelling at dawn, dusk, night, and during rain. Several countermeasures have been proposed based on the findings, including stricter enforcement measures, behavioral modification programs, and technological approaches to improve the situation.
