Who'd have thought it?

I've always thought the main problem with zebra crossings is that it hard for a driver a spot whether there are people waiting to cross (especially where there are many people around). To get round this I have a cunning proposal. They should put a button near each crossing that people can press to indicate that they wish to cross. This would control a red light that would cause traffic to slow down and stop. Perhaps there could also be light for the pedestrians, which could change from red to green to indicate that the traffic has been halted and that it is now safe to cross. Perhaps I should patent this idea.

books for children or adults in the publishing world, and similar in the traffic.

The other one is the Toucan, for bikes…  F

or a motorist, they are all the same, stop when red, and try not to hit folk crossing at the wrong time, for someone will.

Some Belisha beacons are now solar powered.

Mr. B. would be proud.

Leslie's invention.

Does anyone remember the slippery stainless steel ground studs at zebra crossings that caused many a slip up and people going a*** over apex in wet weather?

Pelicans and puffins. What's the difference?

Quite a lot!

For cars, pelicans have a flashing amber phase, puffins do not.

For pedestrians, pelicans have the green and red men on the other side, puffins have them on the same side, so once you have started, you don't know when to start running. Pelicans have a fixed period (depending upon the width of the road), puffins have sensors so in theory you get as long as you need to cross. Pelicans abort the request to stop if a pedestrian is no longer waiting. All clever stuff.

I know that crossing - must have a look some time. 🙂

I think the puffins (which have the “ok to cross” light on the same side as you) are dangerous. At least twice I have started to cross when I misinterpreted which crossing the light indicated  - e.g.  where you're on a traffic island with two crossings close to each other at 90 degrees, and one of the poles holding the “green man” sign is near both crossing points.

They have had LED crossings in Spain for several years. The crossings have a presence detector that lights up the crossing and pedestrian making them very visible. When I have used them, both as a driver and pedestrian I have felt quite safe. Spanish motorists tend to be more willing to stop at crossings than UK drivers anyway (and you can usually tell the UK pedestrians - they thank the motorists for stopping)
