Public Transportation
Overview
Public transportation — including buses, subways, light rail, commuter rail, trolleys, and ferries — has an essential role to play in the toolbox of transportation solutions. Not only will increased ridership significantly reduce emissions, but increased public transportation usage results in better air quality, less traffic congestion, fewer accidents, and decreased noise pollution. Although there is a strong focus on local and regional efforts, states can improve public transportation by (1) controlling funding, (2) prioritizing safer speeds for all people through complete street policies, (3) curbing urban sprawl through planned economic and community development — known as smart growth policies — and (4) creating zoning policies conducive to transit-oriented development.
