U.K. Study Finds Wearing a Bike Helmet May be More Dangerous

ian_walker.jpgWe are certainly still going to be wearing our helmets when we ride bikes on New York City streets, but here is an interesting study by Dr. Ian Walker a "traffic psychologist" from Bath University in Great Britain. Walker found that motorists drove more safely and carefully when passing cyclists who were not wearing helmets. These findings are similar to some of the ideas put forward by David Engwicht in his book, "Mental Speed Bumps: The Smarter Way to Tame Traffic," a very interesting read if you haven’t already picked it up.

As reported by the BBC on Monday:

Cyclists who wear protective helmets are more likely to be knocked down by passing vehicles, new research from Bath University suggests.

The study found drivers tend to pass closer when overtaking cyclists wearing helmets than those who are bare-headed.

To carry out the research, Dr Walker used a bike fitted with a computer and an ultrasonic distance sensor to find drivers were twice as likely to get close to the bicycle, at an average of 8.5cm, when he wore a helmet.

The experiment, which recorded 2,500 overtaking motorists in Salisbury and Bristol, was funded by the Engineering and Physical Sciences Research Council.

"This study suggests wearing a helmet might make a collision more likely in the first place."

Dr Walker thinks the reason drivers give less room to cyclists wearing helmets is because they see them as "Lycra-clad street warriors" and believe they are more predictable than those without.

John Liu: Cyclists Need Helmets, But Not Bike Lanes

What does John Liu think of bikes in NYC? That’s hard to say, and it’s not clear that Liu knows either. On the day when thousands signed up for the city’s bike-share program, exceeding expectations and setting the stage for a major shift in the way many New Yorkers get around, Liu chose to engage […]

A Compulsory Helmet Law Won’t Make NYC Cyclists Safer

|
The great thing about arguments favoring compulsory bike helmet laws is that they tend to stay on topic instead of degenerating into fruitless bickering over cyclists’ interactions with pedestrians, bike riders’ claim to the streets, and other tired subjects. The bad things about such arguments are many. Here are three: They ignore the possibility that […]

From London to D.C., Bike-Sharing Is Safer Than Riding Your Own Bike

|
People riding shared public bicycles appear to be involved in fewer traffic crashes and receive fewer injuries than people riding their personal bicycles. In cities from Paris and London to Washington, D.C. and Mexico City, something about riding a shared bicycle appears to make cycling safer. Paris’s Vélib’ is perhaps the most iconic bike-sharing system […]

Weird Science: Do Helmets Attract Cars to Cyclists?

Following Alex Marshall’s essay on bicycle helmets this morning, Scientific American recently reported on a paradox emerging in relation to helmets and traffic accidents. It seems that drivers are a lot more scared of hitting you if you leave your protective gear at home: Spring is in full swing now, and a number of the […]
