In too many communities, it can be impossible to get around if you don't have a car. In too many communities, sidewalks are few and far between. For too many years, transportation policies have mostly served people using fast-moving vehicles rather than public transit, bicycles or their own two feet. But a street that's safe for a 70-year-old to cross to shop is safe for a 7-year-old walking to school. Complete, smartly planned streets and transportation options are great for people of all ages.
