Portland has a public transportation system. The bus and rail system is operated by TriMet, its name reflecting the three metropolitan area counties it serves (Multnomah, Clackamas, and Washington). Portland's rate of public transit use (12.6% of commutes in 2008) is comparable to much larger cities like Los Angeles, and higher than in most similarly sized U.S. cities, but is lower than in some others, such as Baltimore and Seattle. Transit service between Portland and Vancouver, Washington, the second-largest city in the metropolitan area, is provided by C-Tran, with a small number of express routes.
