The traditional system runs a variety of bus types, operated by several companies on normal streets and avenues: "Bus" (large buses), "Buseta" (medium size buses) and "Colectivo" (vans or minivans). The bigger buses were divided into two categories: "Ejecutivo", which was originally to be a deluxe service and was not to carry standing passengers, and "corriente" or normal service. Since May 2008, all buses run as "corriente" services. Bogotá is a hub for domestic and international bus routes. The Bogotá terminal serves routes to most cities and towns in Colombia and is the largest in the country. There is international service to Ecuador, Perú and Venezuela.
