Motorcyclists’ road safety related behavior at access points on primary roads in Malaysia – A case study

“…This is in line with the findings of previous studies on gapacceptance and time-to-arrival, which pointed out that the most common cause of motorcycle-automobile gap acceptance accidents was motorists infringing motorcyclists' right of way (Harnen et al, 2003;Pai, 2011;Pai et al, 2009;Radin Umar, 2005;Thomson, 1980). Still, our observations also showed that the majority of these serious conflicts occurred more frequently between motorcyclists who entered the primary road and passenger cars on the primary road.…”

Factors Associated with Motorcycle Crashes in New South Wales, Australia, 2004 to 2008

“…By comparison, a somewhat smaller proportion of all vehicle crashes (25%) occur at T-junctions and 17% at crossroads; this statistic suggests that this finding is unlikely to be due to greater exposure to T-junctions than to other intersection types (5). Similar findings in Malaysia have led to the development of specific engineering treatments to reduce such risks for PTWs (22,23).…”

Motorcycle safety programmes in Malaysia: how effective are they?

“…The final model was based on the goodness of fit and the significance test carried out on the models, such as the change in scaled deviance from adding or removing the terms, the ratio of scaled deviance to its degree of freedom (mean deviance) and 't' values of the parameter estimates are significant at 5% significance level. Based on the multivariate analysis, the final model (Harnen et al 2003) where MCA is motorcycle accidents per year, b 5 ¼ 0.0, 0.00903 and 0.02099 for SHDW ¼ 1, 2 and 3, respectively, b 6 ¼ 0.0 and 0.00755 for LU ¼ 1 and 2, respectively. Malaysia 75 The model suggests that the number of motorcycle accidents is proportional to the power of traffic flow.…”
