Public transit is great at reducing congestion. A single subway train can hold a thousand people. With 3 minute intervals, the capacity blows away any road network. However there are different challenges: * Fan out from a transit stop. You need to layer on buses, bike share, and/or car share. And whatever you add needs to have ADA accessible and family friendly options. I love my Hubway key but if I have my kids with me, I have no place to put them [+]. * Building or expanding the damned thing. In particular for me, Boston is sabotaging itself by not aggressively expanding and maintaining its transit system. * Changing American mindsets. Even in cities with relatively good transit systems, there's a mindset that it's dirty, for poor people, or too expensive compared to driving/parking. Car-sharing is a familiar concept for these people: I'm an American, I drive a car to places. +: http://wamu.org/news/14/06/03/dc_couple_invents_kids_seat_for_capital_bikeshare http://wamu.org/news/14/06/03/dc_couple_invents_kids_seat_fo...
