First it was Oasis, now the BBC and the Met Office are getting back together!

The false dichotomy of systemic and individual behaviour change Individuals aren't going to solve climate change, but they are an important part of the system that will get us there.

Which means itโ€™s being produced by water droplets in the air (not ice crystals)

Ah, sorry, they donโ€™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 youโ€™re lucky.

Are parking charges being proposed for on street parking in Marple Bridge then? I hadnโ€™t heard anything about it locally.

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

BlueSkyโ€™s big about alt-text on your images not b/c itโ€™s THE GRAND SOLUTION to accessibility & inclusion. (It is not.)

Itโ€™s entry-level. Something simple you can do *right now* to improve this digital community for those who arenโ€™t like you.

Hereโ€™s a setting to help make it easier.
Use it, please?

I take your point, but not always. If cyclists donโ€™t stop at a zebra and you canโ€™t hear or see them coming, thatโ€™s a recipe for trouble.

I donโ€™t know what the solution is, but I do know it makes it hard for people who canโ€™t see and puts them off going places where theyโ€™re at increased risk

The other thing with the โ€œwe donโ€™t see any increase in accidents etcโ€ is that often blind people will just avoid an area / bus stop if you make it harder to access. That isnโ€™t great really.

The audible signal? For that Iโ€™m thinking a regular 4 way crossing where traffic is under red light control โ€” 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 youโ€™re blind

Should add I have experience of both sides, as a cyclist and with a close family member that canโ€™t see.

12.12.2024 17:31 โ€” ๐Ÿ‘ 1    ๐Ÿ” 0    ๐Ÿ’ฌ 0    ๐Ÿ“Œ 0

all traffic is stopped and itโ€™s clear to cross.

angles as they seem to be with cyclops. I do think this needs some thought though. I wouldnโ€™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

12.12.2024 17:26 โ€” ๐Ÿ‘ 1    ๐Ÿ” 0    ๐Ÿ’ฌ 1    ๐Ÿ“Œ 0

Youโ€™re probably right. One cycle lane added isnโ€™t equal to an extra lane of traffic to cross, but it *is* an additional risk if the cycle lane isnโ€™t as well controlled (zebra rather than red light). The additional crossings themselves also make it harder if you canโ€™t see, esp if theyโ€™re at strange

12.12.2024 17:26 โ€” ๐Ÿ‘ 0    ๐Ÿ” 0    ๐Ÿ’ฌ 1    ๐Ÿ“Œ 0

Yes and some do. Itโ€™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 youโ€™re blind by adding lots of crossings.

12.12.2024 15:12 โ€” ๐Ÿ‘ 1    ๐Ÿ” 0    ๐Ÿ’ฌ 1    ๐Ÿ“Œ 0

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.
