METRO Transit is the city's public transit company. The main transfer terminal is located downtown at NW 5th Street and Hudson Avenue. METRO Transit maintains limited coverage of the city's main street grid using a hub-and-spoke system from the main terminal, making many journeys impractical due to the rather small number of bus routes offered and that most trips require a transfer downtown. The city has recognized that transit as a major issue for the rapidly growing and urbanizing city and has initiated several studies in recent times to improve upon the existing bus system starting with a plan known as the Fixed Guideway Study. This study identified several potential commuter transit routes from the suburbs into downtown OKC as well as feeder-line bus and/or rail routes throughout the city.
