Sometimes we forget that the basic features of city life, while painted on concrete, are not set in stone. Bike lanes were rare until not too long ago. Now they are common, but they all share a problem: intersections are still a free-for-all. Nick Falbo, an urban planner from Portland, has an idea to change that.
Our designs reflect our values. We can have fast-moving cities that favor cars and discourage pedestrians and bikes, or we can slow things down for the automobiles and encourage people to use their feet.
