A '''Transit metropolis''' is an urbanized region with high-quality [[public transport]]ation services and settlement patterns that are conducive to riding public transit.<ref>{{cite book|last1=Cervero|first1=Robert|title=The Transit Metropolis: A Global Inquiry|date=1998|publisher=Island Press|location=WashingrtonWashington|isbn=9781559635912}}</ref> While [[Transit village]]s<ref>{{cite book |last1=Bernick|first1=Michael|last2=Cervero|first2=Robert|title=Transit Villages in the 21st Century |date=1997 |publisher=McGraw Hill |location=New York|isbn=9780070054752}}</ref> and [[Transit-oriented development]]s (TODs)<ref>{{cite book|last1=Calthorpe|first1=Peter|title=The Next American Metropolis: Ecology, Community, and the American Dream|date=1993|publisher=Princeton Architectural Press|location=New York|isbn=9781878271686}}</ref> focus on creating compact, mixed-use neighborhoods around rail stations, transit metropolises represent a regional constellation of TODs that benefit from having both trip origins and destinations oriented to public transport stations. In an effort to reduce mounting traffic congestion problems and improve environmental conditions, a number of Chinese mega-cities, including [[Beijing]] and [[Shenzhen]]<ref>{{cite book|last1=Cervero|first1=Robert|title=The Transit Metropolis|date=2007|publisher=Chinese Architecture and Building Press|location=Beijing}}</ref>, have embraced the transit metropolis model for guiding urban growth and public-transport investment decisions.
