Yeah. I commute 83 daily and still haven't seen a bad wreck around the Northern Parkway bend since they installed these whereas it felt like it used to happen every other week or so in the past. It really felt like you could expect atleast one accident there every time there was a decent bit of inclement weather in that area.

The biggest difference for me anecdotally seems to be that most people just don't weave 80 around that bend anymore, and the ones that try to largely can't because all lanes generally slow to ~55 because of people dodging the cameras. Even if they're successful in going 80 around there for a week or something, I'd bet they'd stop pretty quick after getting pelted with a barrage of $40 tickets.

E: on a slightly unrelated note, I think this is the first time I've seen them actually acknowledge that they can't pull people over even if they wanted to because of the lack of road shoulders...

> BCDOT: Traditional methods of speed enforcement are not possible on I-83 within Baltimore City due to the existing width of roadway shoulders, fiscal and engineering constraints, and resource challenges.
