Re: Pros and cons of hi-vis

. . . workers feel safer when tthey're stood still close to their vehicle. Unfortunately, that vehicle is likely to bd more conspicuous than the worker. So if that person steps out the approaching driver is likely to be dazzled by the vehicle's retro-reflective material and beacons. What am I missi...

Re: Pros and cons of hi-vis

There's a clear progression, for example the typical 'SMIDSY' situation: Driver arrives at junction . . . 1 Doesn't look 2 Looks, but rider is obscured (eg car door pillar, street furniture, other vehicle) [ie 'not visible'] 3 Looks, but doesn't notice the rider 4 Looks, notices the rider, but make...

Re: Pros and cons of hi-vis

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...

Re: Santa list?

With correctly functioning headlights (which I have) and attention to what is in my planned path, I can see completely unlit objects in dark matt colours in good time to not drive into them. It's all very well but, when you throw an oncoming motor vehicle into the mix, then it's bloody hard to see ...

Re: Santa list?

The research results demonstrated that unlike earlier research, road workers were often detected only at short distances, sometimes as low as 25 to 45 meters (27-49 yards). The road workers were also found to be less than conspicuous, even when wearing high-visibility clothing. The workers that wer...

Re: Santa list?

Sure it lights up best in car headlights and if that means I'm seen in the distance, rather than last minute, I think it has a benefit. What do other drivers think? I don't know of any research into HiViz use on the roads which demonstrates a reduction in incident rate or an increase in safety, do ...

Re: Santa list?

That picture nicely illustrates another problem with HiViz when it actually works. The dozy-person's attention is drawn towards the farther rider, away from the nearer. Given that attention is limited, this is bad news for anyone not wearing HiViz. It's a 'beggar thy neighbour' approach in the same...
