Due to the increase in congestion on York Region's roads, York Region Transit launched an express bus service called "Viva" on September 4, 2005. Viva buses only stop at Vivastations, which are specially designed bus stops that incorporate a ticket vending machine and a ticket validator (Viva uses a proof-of-payment fare system to speed up boarding times), as well as a real-time display that predicts when YRT and Viva buses will arrive at the stop. Most Vivastations are blue, but several stops have a bronze design referred to as "vivavintage" in order to better suit the historic areas, especially along Yonge Street in Thornhill. Where there is limited space, miniature "vivamicro" stations are used. Viva abides by YRT's fare policy.
