in recent years, there has been a push to make u.s. cities more “walkable,” through networks of public transportation, as well as sidewalks and a decrease in car-based infrastructure. designed after the people-centered capitals of old europe, washington, d.c., is one of only a few cities in america to achieve this dream.

walkable infrastructure not only makes cities easier to navigate, but can help to reduce environmental costs as well, as transportation is the main source of greenhouse gas emissions in the united states. in addition to the environmental benefits, walkable cities are proven to increase happiness among residents, and switching to public transportation can help the average american save money.
