Free buses in Tempe, Arizona, USA

The other night when we were going to a basketball game at Arizona State University we took the Venus line and then transferred to the Mercury line. And here is the thing. These buses are completely free of charge. The city operates them to encourage people to take public transit rather than drive their own cars. Dave chatted with one of the drivers who said the program has been very successful. Taxes were raised by a tiny percentage point to pay for the Orbit buses.

The city also argued that free public transport including encourage residents to give up cars every day, reduce barriers to access to education, culture or recreation, and improve the situation of large families. "The observations of drivers and our officials show that the number of passengers - from May to July - increased by up to four times in buses" - Anna Ujma from the City Hall in Żory told PAP.
Recently, the local government has suggested to residents that they submit comments on the functioning of free public transport (comments and applications were submitted, among others, by email). As Ujma said, their goal was, among others determining the residents' needs. "The three basic requests concerned especially the introduction of larger buses, adapting the timetable to the needs of students, and increasing the number of stops" - said Ujma.
She added that buses that could accommodate more passengers than previously appeared on route 5 in the Rój district and on route 6 in the Baranowice district, three new stop locations are being prepared, including at the Sikorski estate
