I really like the build out on this side road junction, on Lamb's Conduit Street, London. It adds to a great walk and cycle environment by calming traffic at crticial point & creates space for street furniture to keep footways clear. The street trees are magnificent here too, as is the heritage lamp

Very well designed bus stop island in Bristol. Yes there's lots of space here but it was previously wasted on wider-than-standard road lanes. There are still 2 road lanes, but also now so much more! Lots of streets have redundant space that can be better used - once you see it, you see it everywhere

Also in Bristol (same road) is this bus stop/taxi rank island. I feel the guard railing is, overall, helpful. The crossing point is well defined & easy to find. Fake zebra markings falsely imply to peds that bikes must stop; I'd give peds clear priority. But I think this is generally well designed

Seen in Bristol: loading bay in a cycle lane, but bikes able to mount footway to pass any parked delivery van. For me it's confusing & half-hearted. Transitions & bollards narrow the footway. Would a delivery space at footway level to left of cycle lane be better? Peds get full width when not used?

I do think tiger crossings are awkward, but here is one that works better than most I feel (Liverpool Rd, Islington). You can almost use it to bike from anywhere to anywhere at this staggered junction, but it still doesn't allow a right turn (as the camera faces). The bike lane was well used though!

Flexible bollards used to 'lightly' segregate bike lanes from general traffic quickly look discoloured and cheap after installation - they look like clutter, like carelessly abandoned roadwork cones. Sussex Gardens, London, has tulip shaped flex bollards that overcome these issues - they look great!

Tiger crossings sound like great bike infrastructure. But they can prevent bikes turning left or right, & engineering convention is to site them awkwardly away from the desire line to prevent people walk/cycling straight out into the road. Most times, instead you need a junction with cycle-only arms
