The mayor of Hoboken, NJ came in with a vision of reducing traffic deaths to pedestrians and cyclists. He instituted several strategies of traffic calming, increasing pedestrian visibility, reducing city wide street speeds to 20 mph with schools and parks down to 15 mph. Within a few years of road improvements and redesigns their pedestrian traffic deaths to zero for several years.
The article does note that half of the streets have bike lanes, they’ve put buffers between pedestrians and cars, and continue to redesign intersections with a focus on safety instead of just focusing on car speed/throughput.
The bike lanes suck though. They are next to the street, instead of behind the parking and next to the sidewalk. As a result, on the main street in Hoboken (Washington street), there are always cars double parked in the bike lane during the day or drinking hours of the night, because parking in that city is horrendous. It’s common to see an entire block or two full of cars double parked in the bike lane, making it unusable. Also, they redid the bike lane with textured hexagonal bullshit so using any wheels smaller than e-scooter wheels (skateboard, roller skate) is just a super rough ride.
Great that he stopped pedestrian casualties, but he severely harmed personal non-car transit.
