This Transit Cooperative Research Program (TCRP) digest summarizes the results of a mission performed from June 11 through 25, 2010, under TCRP Project J-03, International Transit Studies Program. This digest examines how bus and rail agencies and operators in several European cities develop community support for public transportation and how those communities implement sustainable funding strategies for transit assets, operations, and maintenance. The cities visited include London and Nottingham, United Kingdom; Strasbourg, France; Karlsruhe and Berlin, Germany; and Oslo, Norway.
