Herts road safety wade into the debate.

Ace. Glad the message is getting through .

If only they would 'debate' the issue...

"To help you keep safe..."

"You'll then be spotted..."

No wonder so many riders still don high vis and reflective riding kit and wake up in hospital wondering what hit them.

Sadly, it's one of their contributions to Think Bike week.

I guess the Herts Road Safety massif haven't seen the evidence regarding hi-viz. We need to make this evidence more conspicuous

Aside from Herts Road Safety being all at sea, a more important question is why are lifeboats orange, but lifeboat crew wear yellow?

Lovely video (except for the "music" - may thanks for that.

For 'lifeboat' in the widest sense:




EVERYTHING YOU NEED TO KNOW ABOUT LIFEBOATS
20th Jan 2020

SOLAS Regulations list some specific standards which every vessel shall observe with relation to lifeboats and their use. Let’s take a look at these regulations below –

SOLAS Requirements for Lifeboats

According to the LSA codes and SOLAS, there is a set of requirements that ensure the safety on a lifeboat. These requirements are:

The Lifeboats are to be painted with an internationally-approved bright orange colour and the ship’s call sign is to be printed on it.

1980s: Back to yellow
The 1980s saw the lessons learned with our orange all-weather gear transfer over to a new, brighter, and easier-to-spot yellow kit tested at the RAF Institute of Aviation Medicine.

The RAF you say?

... Apart from the all-black paint scheme being important for conspicuity when it's in the sky, not the sea

Whereas ...

Your man is in the sky...

Looked but failed to sea ?

Ok, try this one. The picture has two sets of boat/person/aircraft. One set are all in conspicuous colours.

Used to have SOLAS tape on the panniers on the Tiger. Often felt a nudge on the bike when filtering at night where riders had tried to filter past but failed to see the panniers (seriously poor obs).

I can’t see the set that’s invisible to me.

That must prove something.

I drive a 9 foot wide, 15 foot tall, 38 foot long bus, painted bright pink, with HID lights on the front of it. I get at least a hundred people pulling out on me every working day.

You can be as visible as humanly possible but it means nowt if people don't look.

At work if I'm out on a construction site I wear a combination of yellow jacket and orange trouses to cover all options. I also have a ligthweight vented jacket which is half yellow half orange.
I think the colour worn is important to the environment you are in and the time of year. looking out the window now with the sun on the grass and trees a bright yellow jacket would blend into the background. Where as in the Autumn a orange jacket may blend into the background as the leaves die out.
Around town and along the road side there are often lots of yellow signs but very few orange.
I have a black bike with the headlight permanetly on and a red bike with a fluoresent orange high viz panel at the front. i still choose to ride with a headlight on but I don't ride wearing high viz.

I often wear an orange hi-viz gillet on the bike. Not because it is hi-viz, but because it is

a) cheap as chips
b) warm, butt easily removable if not needed
c) waterproof against occasional showers

I agree, and it's why you need a pink jacket

In Science Of Being Seen, I have written:
----------------------

It should be obvious that whether or not a motorcyclist stands out depends at least partly on what is behind the rider. What matters is not so much whether the rider is using light coloured clothing or a low beam headlight so much as whether that creates contrast between rider and the background. Many of the studies – which are still quoted and still used as evidence for the effectiveness of conspicuity aids – placed the rider against a relatively uniform backdrop.

There was a second problem – motorcycles are usually moving in front of other moving vehicles, and many of these studies – particularly the early ones – used photos which required the subjects to detect a static motorcycle against a static background. More recent studies have become aware of these limitations. For example, Pai in a literature survey published in 2011 noted that:

“A substantial number of studies have manipulated physical characteristics of motorcycles and motorcyclists to enhance conspicuity… Although various conspicuity aids have proven effective, some researchers reported that motorcyclist’s/motorcycle’s brightness per se may be less important as a determinant of conspicuity than brightness contrast between the motorcyclists and the surroundings.”

In their book on motorcycle conspicuity, Roessger et al (2015) state:

“PTW conspicuity may be related to the motorcycle, to other vehicles, to the riders themselves, to other drivers, to the road environment or any combination of these factors… for example, riders can use daytime riding lights to decrease their probability of collision with another vehicle, but they do not control ambient traffic conditions… most importantly, conspicuity is not constant but changes with the time of day, the weather conditions, the urban environment, the presence of absence of other road users.”

In other words, the most conspicuous clothing and lighting changes moment-by-moment depending on the and local environment – there is no straightforward ‘one size fits all’ solution.

@The Spin Doctor You can't fool me. I know what you're wearing and here's the photographic evidence:

I put my ideas together on an early post on my ‘blog before they were called blogs’ way back in the early 2000s – you can still find that post [...] when I attended a Metropolitan Police BikeSafe course, I was surprised to discover that hi-vis clothing wasn’t top of the list in a discussion of possible strategies. Whilst hi-vis still promoted as a good thing, the big difference was that its limitations were also discussed. The presenter explained how it needed a background contrast to work, and also suggested that the use of Saturn Yellow hi-vis has become saturated because everyone uses hi-vis yellow.

And pink got a mention. Now, I wonder where they got that from?
