I noticed the city has installed these sidewalk ramp bumps known as truncated domes. From what I can google it is to make the sidewalks wheelchair accessible and assist people with disabilities. Apparently they are quite expensive and so may cause some controversy.
I found this Philadelphia article from 2012 that says each ramp costs $7500 or $60,000 per intersection or $858 million for that city. I also read some articles where people find them helpful and some where they do not. I can certainly understand how it could help a blind person.

I saw these everywhere in Japan. They are very accommodating to disabled people. The U.S. is trying.
They are everywhere here, too, and very useful or people with wheelchairs, walkers, prams etc. Have a good week, hugs, Valerie
Almost every sidewalk in England I've seen has these little bumps. They're at every pedestrian crossing at least. I was under the impression it was to help blind people cross the road.
These are necessary for people who have disabilities.
I have never seen them here in Hawaii, but they do sound expensive.
they need to find a cheaper way to make those, jeez
I was on a tour with a blind person and he said that he hated those bumps. they were made more for wheelchairs and walkers to be able to get a grip and not slide on the concrete but this gentleman said he didn't think those with the mobility devices liked them either. We had quite the chat about the installation of the bumps since I thought they were doing disabled people some good.
interesting feedback Delaine, thanks.
I hadn't seen them before. I hope they're more helpful than not helpful, especially given the price...
I think we have some in our city too, but I didn't know it is that expensive! It is helpful for many people indeed!
we don't have here such facilities as most of the budget goes into the pockets of politicians who make government and with this money they make sidewalks for themselves and their generations to come ,
highways are built better but roads in small cities are really worse
