I read the StreetsBlogUSA post Study: Diagonal Intersections are Especially Dangerous for Cyclists today with great interest, for a number of reasons that I thought I would share with you.

Firstly, there is no doubt that cyclists are a vulnerable road user group, and that particular segments of road are more problematic for cyclists. The research cited in the post pertains to an Injury Prevention publication which examined, in-depth, police reports of 300 car-cyclist crashes in the New York city area , and the police templates to record crash-pertinent information across the US. Innovative research which approaches a known problem from novel perspectives helps to provide additional pieces for the jigsaw puzzle that we seek to solve, and this research was an intriguing read indeed.

Secondly, the research revealed that some road configurations appeared to increase crash risk (i.e., we want to reconfigure these roads), and that the safest option in the most problematic circumstances was to separate the motor vehicle from the vulnerable cyclist. The ‘solution’ for cyclist safety can be a highly contentious issue, particularly here in Australia in which the motor vehicle has traditionally – through necessity – dominated our vast landscape, and as health and other benefits become apparent, cycling is gaining traction. Indeed, Cadel Evans, arguably Australia’s most celebrated cyclist, has tried to bring clarity to this divisive issue; stating that

“I don’t think we should separate the two, because most people who ride a bike also have a car. In the end, they’re public roads for everyone. It’s a privilege to use roads; not a right.

 We have to respect everyone who’s using them, whether they’re driving a car, bus, tractor or truck, or riding a bike or are a pedestrian. We have to respect each other’s privilege and safety.”

in response to the question “What do you say to drivers who think cyclists don’t belong on the road?”

Thirdly, the innovative solution of the peanutabout helps speak to ideas beyond the cyclist themselves – this is consistent with systems thinking which argues that safety (in this case, cyclist safety) emerges from a complex web of actions and interactions among a breadth of stakeholders who play a role in the larger safety system (e.g., in the case of my own research interests, an application of systems thinking in the young driver road safety). Given we are more than half way through the Decade of Action for Road Safety, and in the case of Australia, our road toll returned to an upward trajectory in 2016 after many years of a downward trajectory, such innovative thinking is critical.

Fourthly, the researchers noted that the templates used by police to record crash-pertinent information did not provide adequate details regarding the crash circumstances. Unfortunately this is not an uncommon problem, and again one that I have come across in my own research endeavours. If we are to effectively prevent injury, we need as much contextual and other information regarding the incident contributing to the injury.

Fifthly, while the peanutabout appears to be an ideal solution to the critical issues identified for the area noted, I am mindful that drivers do not always ‘cope well’ with complex infrastructure such as roundabouts. As a researcher within the realm of young driver road safety, and the mother of teen with the learner licence which requires full supervision whenever she is behind the wheel, Learner drivers often tell me that they ‘freak out’ when they come to a roundabout, and it is not actually round! According to Learners, roundabouts must be round, while oval roundabouts and others shaped as a parallelogram should be called something different. Hmmmm, on reflection, maybe Learners will be okay with a ‘peanutabout’…..

Finally, I paused to reflect on the safety implications for motorcyclists – another vulnerable road user group. While traversing a roundabout on his Harley Davidson last year, a colleague was driven over by a driver behind the wheel of 4WD, texting, who reported that she had checked the roundabout for vehicles before entering, and that she did not see – or hear – my colleague already on the roundabout (and thus he had right of way) until her front right tyre was on top of his leg and his motorbike. Thankfully he has managed to retain his leg, however he has had multiple operations, requires additional surgery, and will be scarred for life and never walk without support again. My colleague is the first to acknowledge that motorcyclists sometimes deliberately place themselves in danger through their riding behaviours – himself included – however we both eagerly await any intervention that will increase motorcycle safety when traversing complex infrastructure such as roundabouts.
