Boston Globe: “Some city councilors want a 20 mph speed limit in Boston”

Even supporters of a change to 20 miles per hour argue a speed limit change is not by itself enough to protect pedestrians. Cities and towns must also design streets to encourage slower driving, said Wendy Landman, executive director of the pedestrian advocacy group WalkBoston.

“Simply changing the speed limit without doing anything about the built environment does a little, but not nearly enough,” she said.

Bike lanes, raised crosswalks, streetside landscaping, and thinner travel lanes are among the traffic-calming measures that actually influence drivers to go slower, Landman said.
