Holy shit. There's already a memorial there. We have a few roads like this in Portland where pedestrians and cyclists get killed over and over. The city responded by putting up new speed limit signs and one of those radar speed displays but it hasn't changed anything. Folks still drive as recklessly as ever.
Why not put bollards there to protect anyone on the island from being mowed down? Cheaper than the camera and safer. The families should sue the hell out of the city for not putting a protective barrier there after the first death.
Someone who's going to crash into a pedestrian doesn't care what the speed limit sign says, and the radar speed signs can't give you a ticket so people just speed up to get a high score.
I think the real problem is the pedestrians don't have any physical protection. It is a numbers game. Even if 99.9999% of drivers can navigate that intersection fine, it doesn't take long for the 1/1,000,000 that is drunk, up all night with a sick infant, etc to plow into pedestrians. Probably every month or two based on that kind of road's capacity. People need to start suing and make it too expensive to not put barriers around the pedestrian island.
