Valley Metro operates bus routes and the Valley Metro Rail system that serves Downtown Tempe and Arizona State University, providing service to Phoenix and Mesa. The City of Tempe operates a free neighborhood circulator service called Orbit involving five free shuttle routes near Arizona State University that operate on a regular basis seven days a week. Three other FLASH (Free Local Area Shuttle) circulate in northern Tempe around the university. Tempe residents and commuters make extensive use of public transit and service is offered on a more frequent basis than elsewhere in the greater Phoenix valley, or in the entire state. Most Tempe buses offer 15 minute service during rush hour and 30 minute service throughout the rest of the day.
