Last week, former New York City transportation commissioner Janette Sadik-Khan spoke in support of rethinking the way that we approach transportation in the United States. Sadik-Khan’s vision of a transportation future centered around “people first districts” in which priority is placed on forms of active mobility and public transportation rather than on private automobiles. Reducing the reliance that the average American currently has on their car as a form of transportation could have significant economic, environmental and public health benefits.
