Sun Rideshare provides commuter services through a free, online matching database for people interested in sharing the ride. Sharing the ride through carpooling or vanpooling offers you a chance to save time and money, while reducing stress, traffic congestion and pollution. Using an alternative mode of transportation one or two days each week does make a difference in reducing your fuel costs, vehicle emissions and possible wear and tear on your vehicle. Commuters sharing the ride may be eligible for the Guaranteed Ride Home program, which provides free taxi rides home from work when there is a family emergency or unscheduled overtime.

Commuter Spotlight: Shellesa Harden, CoWorkx Staffing Services

Shellese Harden, an advocate at CoWorx Staffing Services, regularly takes alternative modes to work. She rides the bus three times a week and walks the other two days.

“[Riding the bus and walking] gives me time to focus on myself and get ready for my work day,” Harden said. She also likes to take the bus and walk because it has madeher more active and helped her lose weight.

This kind of transportation has a slew of benefits. Walking, biking and generally taking more active transportation (including walking to and from bus stops) increase physical activity,  which can improve fitness, help with weight loss and reduce the risk of chronic disease. Active transportation also can help reduce stress. “[Walking and riding the bus] really helps me to clear my mind,” she said.

Harden’s active transportation lifestyle has made her healthier and more prepared for work, and it also has other added benefits. Walking and taking the bus helps her save money, as she  is not spending as much on gas for her car. She’s also saving on maintenance and depreciation costs – according to AAA, it costs $8,876 per year on average to drive alone.

With her regular schedule, the only challenge Harden comes across is when the buses are running late. Other coworkers have had difficulty parking in the crowded lot, so she enjoys not having to worry about finding a space in the morning.

Guaranteed Ride Home Program (Español

One of the main obstacles to using an alternative mode of transportation for commuting is the fear of being stranded at work without transportation. What happens when your child is sick at school and you carpooled that day? Or your boss asks you to stay late to finish a project and the last bus leaves at 7 p.m. Pima Association of Governments and Sun Tran provide a Guaranteed Ride Home for just these types of situations. GRH is free taxi service for registered commuters when there is an emergency or unexpected overtime.

To qualify for GRH, you must use an alternative mode of transportation, such as carpooling, vanpooling, biking, riding the bus, and walking at least twice a week. All participants must live and work in Pima County. You can register your commute with PAG by:

Once you are registered, a taxi voucher will be available as needed in the Sun Rideshare Travel Database. Login with your email address and password and follow the instructions to print a voucher. If you do not have an email address, a paper voucher will be sent to your home address to use in the case of an emergency. Each registrant can use up to four vouchers every 12 months. A supervisor’s signature is required on all vouchers.  GRH vouchers can only be used to travel home from work.

Qualifying emergencies:

  • Personal or family illness
  • Personal or family emergency
  • Unexpected overtime
  • You are left without a ride because your carpool or vanpool driver had an emergency
