A study by University of Bath psychological scientist Ian Walker finds that high-visibility clothing is unlikely to prevent the most dangerous passing behavior from drivers. Around 1–2% of overtakes were within 50 cm (about 18 inches) of the rider regardless of what he wore, implying a small proportion of motorists’ passes will always be dangerously close regardless of what a bicyclist wears.

“Many people have theories to say that cyclists can make themselves safer if they wear this or that. Our study suggests that, no matter what you wear, it will do nothing to prevent a small minority of people from getting dangerously close when they overtake you,” says Walker.

A past study from Walker demonstrated that drivers actually encroached much closer to cyclists wearing helmets than those without one. Drivers perceived helmeted riders as more experienced, and thus assumed they could get closer to them as they passed. The research team wanted to investigate whether a bicyclist’s outfit would influence perceptions of experience, and hence, how close drivers got while passing.

A member of the research team, Ian Garrard from Brunel University, used an ultrasonic distance sensor to record how close each vehicle passed during his daily bike commute between Berkshire and outer London (about 50 km round trip). Over several months, data were collected from 5,690 passing vehicles.

Seven outfits were tested, ranging from a specialized racing cyclist outfit—implying high experience and skill—to a vest with “novice cyclist” printed on the back, clearly communicating low experience.

Some outfits included a high-visibility bicycling jacket or high-visibility safety vests. One vest prominently displayed the word ‘police’ along with a warning that the rider was video-recording their journey. For comparison, another high-visibility vest was modeled after a police officer’s jacket but with one change—it read “polite” instead of “police
.”

My bold highlighting.

While the POLITE vests are annoying (to me), this HiViz setup has always brought a smile (and done long before the Polite vests appeared).

Not seen the pianist. Any idea who & where?

But anyway, you've got me started now :) :oops: :lol:

Do you know about the Berlin Brigade? As the name implies, it was our army of occupation. They had a distinctive colour scheme. Each 'type' eg Landie or Chieftan, had identical patterning so that it was difficult to determine quite how many were passing :)

Surprisingly effective. Now, where did I leave my tank . . . ?

Image

But I'm sure I've seen that sort of pattern recently . . .

Final one hints at something I think you mentioned a few posts back, compared to the 'solid' colour scheme as proposed by HOSDB for police bikes, and also demonstrated by this guy:

And finally . . .

Don't know who but the pic was taken in Brentwood October 2004 according to Flickr. It used to be seen around the Essex, Chelmsford area.

Interestingly one of our IAM Group members (a past Associate of mine) IS a professional pianist and takes his keyboard (sawn in half) plus small PA about to gigs in a trailer on an ex police RT single seat BMW. It is NOT done up like this.

There's a good comment in the article you linked to Horse pointing out the test is not really that scientific.

The test is trying to suggest that HiViz gives no benefit because drivers were still to close. That reminds of the oft quoted "It's not a force field". The purpose of HiViz is to get you seen (and we all have our own views/beliefs on how well that works) and not to magically turn an aggressive/inconsiderate drive in to a fluffy bunny of a driver.

My own experience is that when wearing a HiViz tabard while out with Associates is that it INCREASES driver aggression/impatience ... or is it I'm going much slower a lot of the time?
