Thoughtfully designed and appropriate to the surroundings. It’s a continuum. It is not just building sidewalks and bike lanes everywhere

Crossing the Street
Pedestrians cross the street because there are things they want to get to…a bus stop, a store, a neighbor…but how we design makes all the difference.

Speed and Crash Severity
As a pedestrian, if I am to be hit, I want to be hit slowly.
20 mph = 15% fatal
40 mph = 85% fatal
