Boston’s version of Vision Zero, an idea that originated in Sweden more than two decades ago, sets as its target zero fatalities or serious injuries by 2030 among people who walk, bicycle, or drive.

A recent policy report from the Vision Zero Coalition indicates the number of fatalities has been declining in Boston, falling from 21 in 2016 to 10 in 2018, with the number of pedestrian fatalities dropping from 14 to 7 over that time period. But the number of crashes that required response by emergency medical service teams actually increased slightly, rising from 4,355 in 2016 to 4,367 in 2018.

“Generally speaking the trend lines are better, or at least they’re not any worse, than when the program was adopted,” said Matthew Lawlor, who is active in WalkUP Roslindale. “We’re making progress, but those of us who are advocates think progress isn’t coming fast enough.”
