“…Driver failure to see two-wheelers, difficulty in determining motorcycle speeds, and reduced conspicuity of two-wheelers have been identified as important causes of 'failure to give way' type crashes in many studies (e.g., Haque et al, 2012;Horswill et al, 2005;Pai, 2011b;Pai et al, 2009). While driver attention is important, improving conspicuity of riders by using illuminated lights, wearing reflective clothing, and using retro-reflective marking on helmets and two-wheelers could potentially improve rider safety.…”

“…Smaller size and less intensity of bicycle lights could explain why drivers failed to give way to bicyclists more often at night than motorcyclists. Increasing the conspicuity of riders and two-wheelers to improve safety has been recommended in a number of studies (Haque et al, 2012;Pai et al, 2009;Thornley et al, 2008;Wood et al, 2009;Yuan, 2000). In addition to headlight (static or blinking), reflective vest, and reflective markings on two-wheelers, researchers (Wood et al, 2012) have suggested use of ankle and knee reflectors for bicyclists.…”

“…The limited conspicuity of bicycles and motorcycles and consequently drivers failing to see them or giveway to them have been identified as contributing factors in many studies (e.g., Haque et al, 2012;Horswill et al, 2005;Pai, 2011b;Pai et al, 2009), which implies that there might be similarities between bicycle and motorcycle crashes, particularly at give-way situations. Other authors have suggested that drivers' perception of motorcycles as less threatening than other large vehicles may also contribute to them failing to give way (see Pai, 2011a).…”

This paper explores the similarities and differences between bicycle and motorcycle crashes with other motor vehicles. If similar treatments can be effective for both bicycle and motorcycle crashes, then greater benefits in terms crash costs saved may be possible for the same investment in treatments. To reduce the biases associated with under-reporting of these crashes to police, property damage and minor injury crashes were excluded. The most common crash type for both bicycles (31.1%) and motorcycles (24.5%) was intersection from adjacent approaches. Drivers of other vehicles were coded most at fault in the majority of two-unit bicycle (57.0%) and motorcycle crashes (62.7%). The crash types, patterns of fault and factors affecting fault were generally similar for bicycle and motorcycle crashes. This confirms the need to combat the factors contributing to failure of other drivers to yield right of way to two-wheelers, and suggest that some of these actions should prove beneficial to the safety of both motorized and non-motorized two-wheelers. In contrast, child bicyclists were more often at fault, particularly in crashes involving a vehicle leaving the driveway or footpath. The greater reporting of violations by riders and drivers in motorcycle crashes also deserves further investigation.

“…The ROW of motorcyclists are more likely to be violated by turning motorists at unsignalized T junctions (Pai and Saleh, 2008), non-built-up roads and in diminished light conditions (Pai et al, 2009). Higher driver workload during turning manoeuvres at intersections has also been reported to be a significant factor for detection failure of motorcycles (Hancock et al, 1990).…”

“…Research on the crash risk of motorcyclists has investigated a variety of issues, such as rider attributes (e.g., Chang and Yeh, 2007;Lin et al, 2003), motorcycle characteristics (e.g., Haworth et al, 2009;Langley et al, 2000), roadway, environmental and traffic factors (e.g., Haque et al, 2010;Kim and Boski, 2001), conspicuity of motorcycles (e.g., Yuan, 2000), over-exposure of motorcycles at intersections (e.g., Haque et al, 2008) and gap acceptance manoeuvres at junctions (e.g., Crundall, Humphrey, et al, 2008;Pai et al, 2009). One predominant finding of motorcycle safety is that motorcycle crashes are more likely to occur at intersections with other vehicles violating the right-of-way (ROW) of motorcycles (Hurt et al, 1981).…”

An investigation on multi-vehicle motorcycle crashes using log-linear models

2012

Motorcyclists are the most crash-prone road-user group in many Asian countries including Singapore; however, factors influencing motorcycle crashes are still not well understood. This study examines the effects of various roadway characteristics, traffic control measures and environmental factors on motorcycle crashes at different location types including expressways and intersections. Using techniques of categorical data analysis, this study has developed a set of log-linear models to investigate multi-vehicle motorcycle crashes in Singapore. Motorcycle crash risks in different circumstances have been calculated after controlling for the exposure estimated by the induced exposure technique. Results show that night-time influence increases crash risks of motorcycles particularly during merging and diverging manoeuvres on expressways, and turning manoeuvres at intersections. Riders appear to exercise more care while riding on wet road surfaces particularly during night. Many hazardous interactions at intersections tend to be related to the failure of drivers to notice a motorcycle as well as to judge correctly the speed/distance of an oncoming motorcycle. Road side conflicts due to stopping/waiting vehicles and interactions with opposing traffic on undivided roads have been found to be as detrimental factors on motorcycle safety along arterial, main and local roads away from intersections. Based on the findings of this study, several targeted countermeasures in the form of legislations, rider training, and safety awareness programmes have been recommended.
