Yes, klinkers aren’t laid directly on the ground, it usually has a layer of sloped gravel and another layer of sand/fine gravel compacted with a vibrating plate, which prevents water pooling between and beneath them in the first place

I’m glad to hear that, I think it wasn’t documented last time I searched for it, but it works, as seen here: https://fedecan.ca/en/guide/lemmy/for-users/markdown

I’ll update the post

This comment actually got me curious, so I found these numbers for cities with population around ~1.1 to ~1.4mi

Can you guess which cities are actively investing in their vision zero programs and reforms?

Lemmy doesnt like tables, so I’m sorry in advance:

Numbers normalized to 100,000 population

I was going to try go get 5 cities per continent, but I ran out of time. I think we already can get a good picture.

Population taken from 2025 numbers https://worldpopulationreview.com/cities which says it sources from https://esa.un.org/unpd/wup/ (currently down for maintenance). It was not ideal to use 2025 numbers, but differences would be minimal based on annual growth

Latest source data available was used, which is around 2022-2025. There are PDF links, open with caution
