Kinda.

In South Kensington, they spent a fortune trying to use this non-delineated road setup where its not clear quite where the pavements (sidewalks for the USians), and road borders are, and in theory it means everybody just becomes very hyper aware of each other.

The theory goes something like how cycle lanes - just the a white line down the side of the road - can cause drivers to pass much closer to cyclists than they otherwise would without that border there, where a driver might slow and move a few feet out to the side on a single carriageway.

In reality, it's actually kind of anxiety inducing, particularly if you're in a larger crowd (common at this time of year, as Royal Albert Hall where proms season is coming to a close is at one end of this area), because drivers don't really seem to know what is going on.

I suspect it means cars are, on average, slowing down, but I can't find stats on whether its reduced accidents or not. I know it makes me nervous though.

It’s South Kensington, part of council that’s notorious for its hatred of anything that even vaguely looks like a bike or a bike lane. Their attitudes to road design are despicable, with a clear priority for cars over any other road user. It often feels like they only provide pedestrian or cycle infrastructure as a grudging acknowledgement of the fact the vast majority of people walk or cycle, and car users are in the minority.

All of that is a long way of saying that any road infrastructure South Kensington designed is going to be a long way behind best practice for pedestrian safety, even when they’re trying.
