“…The database was based on the similar concept of a police crash database, but with a crash contributing factors as the main theme. Although the majority of earlier naturalistic studies used passenger car as the test vehicle, a considerable literature has grown up in recent years around the theme of naturalistic motorcycle riding data collection (e.g., Dozza & Werneke, 2014;Spyropoulou et al, 2010;Ibrahim et al, 2012;Ibrahim et al, 2018;Ibrahim et al, 2014;Ibrahim & Yusoff, 2011;Ibrahim & Sukardi, 2011;Lemonakis et al, 2014;Vlahogianni et al, 2014). The present study describes the experimental methodology and discusses the analysis of crash-relevant events recorded in a pilot study of a large-scale naturalistic motorcycle riding data collection within the Malaysian traffic environment.…”
