Speed bumps are the worst possible solution, they often mean if you’re in a conventional car you have to come to a near complete stop and if you’re in a large SUV you can cross at 20mph. This reinforces the trend away from conventional cars to higher ride height vehicles which is a disaster for road safety (especially pedestrian and cyclist safety).
They do successfully slow down the flow of traffic (and also cause traffic to follow alternative paths, at least until speed bumps are saturated in the area) but it fucks up emergency vehicle access and damages cars (increases wear and tear). The other road design solutions (more narrow roads, inclusion of roundabouts, addition of choke points etc) all are equally as effective as humps at reducing speeders and diverting traffic away from roads (in some cases they are better) and have none of the negative consequences, speed humps should never be used imo.
The speed bumps are supposed to be tailored to the target speed. There’s some 40 km/h streets in my city with regular speed bumps and they’re perfectly fine because the speed bumps are designed for that speed. They’re quite shallow compared to the kind of speed bump you’d see in a 20 km/h parking lot.
I’ve never seen or heard of this but I’m skeptical that there is any speed hump design that wouldn’t be a negative for emergency services, increase wear and tear to vehicles that cross them and that wouldn’t be less of an impact to lifted chassis vehicles. These problems are avoided by the other, better solutions so why are humps even a part of the conversation at all?
