Ah, sorry, they don’t. Droplets are spherical and give rise to rainbows and moon bows, but ice crystals are hexagonal plates and columns and produce halos around the sun or moon (22 and 46 degrees from it) and more complicated displays if you’re lucky.

Very nice, though if it’s a moonbow (on the opposite side of the sky from the moon), it’ll be moonlight interacting with water droplets. If was interacting with ice crystals it’ll be around the moon and be a halo, I understand?

I take your point, but not always. If cyclists don’t stop at a zebra and you can’t hear or see them coming, that’s a recipe for trouble.
I don’t know what the solution is, but I do know it makes it hard for people who can’t see and puts them off going places where they’re at increased risk

The other thing with the “we don’t see any increase in accidents etc” is that often blind people will just avoid an area / bus stop if you make it harder to access. That isn’t great really.

The audible signal? For that I’m thinking a regular 4 way crossing where traffic is under red light control — that should also apply to the segregated cycle lanes. Pedestrians then only have one crossing that they know is clear and safe. Floating bus lanes are harder, but do add risk if you’re blind

angles as they seem to be with cyclops. I do think this needs some thought though. I wouldn’t like to have to cross a cycle lane on only a zebra when delivery drivers are doing 20mph on e-bikes and rarely stop at the best of times with my eyes closed. What you need is an audible signal telling you

You’re probably right. One cycle lane added isn’t equal to an extra lane of traffic to cross, but it *is* an additional risk if the cycle lane isn’t as well controlled (zebra rather than red light). The additional crossings themselves also make it harder if you can’t see, esp if they’re at strange

Yes and some do. It’s not an argument for banning all cycle lanes, the problem is that is comes on the inside of the bus. At most junctions though they could be segregated, but under red light control. Cyclops junctions similarly make life really hard if you’re blind by adding lots of crossings.

You're adding a crossing to and from the bus stop, where there previously wasn't one. If you're blind you can't hear the cycles coming, and there's usually limited compliance with the pelican crossing i.e. cyclists often don't stop. The result is an increased risk for the mot vulnerable group.
