Individual incentives for public transportation

Evidence Rating

Some Evidence

Health Factors

Decision Makers

Incentives such as free or discounted bus, rail, or transit passes reimbursements, partial payments (), or pre-tax payroll deductions (NCTR-Commuter benefits) decrease consumers’ cost to use public transportation. Incentives are typically offered by employers as a commuter benefit and can be part of transportation subsidy programs, deep discounting, or transit pass incentive programs ().

Expected Beneficial Outcomes (Rated)

  • Increased use of public transit

  • Increased physical activity

Other Potential Beneficial Outcomes

  • Increased active transportation

  • Reduced obesity rates

  • Increased mobility

  • Reduced vehicle miles traveled

  • Reduced emissions

Evidence of Effectiveness

There is some evidence that offering individual incentives for public transit increases public transit use (VTPI-Litman 2017a, , , , , ). Such incentives can also increase physical activity for individuals who use non-motorized travel to and from transit stops (, MacDonald 2010, , , Hipp 2017, ). However, additional evidence is needed to confirm effects.

Combining incentives such as discounted passes with improved transit service and higher private vehicle user fees (e.g., increased parking costs) can increase public transit use and reduce automobile use (, VTPI-Litman 2017a). Individual incentive programs that combine discounted transit passes with parking reimbursement (Lari 2014) and efforts to market incentives to employees can also increase transit use (VTPI-Litman 2017a). Transit pass incentive programs have been particularly successful in increasing use among college students (, ). High gas prices (, Iseki 2014, ), not having children, and having a flexible schedule or one that matches transit availability also increase the likelihood of using a transit pass ().

Model-based research suggests that reducing fares may generate small increases in transit use, while increasing fares may significantly reduce use (). Overall, price sensitivity to fares depends on whether a traveler is transit dependent (, VTPI-Litman 2017a), the type of trip, time of day, and geographic conditions such as population density and the character of the built environment (VTPI-Litman 2017a). Distance-based fare reductions may increase ridership among low income households and elderly and minority individuals, who often use public transit to travel shorter distances than wealthier, younger, or white riders ().

Transit users have higher levels of physical activity than non-transit users (, Lachapelle 2009, ). Incentives for public transit use have been shown to increase active travel options such as walking and cycling (, ), which may reduce the likelihood of becoming obese (MacDonald 2010, ).

Individual incentives are a suggested strategy to reduce single occupancy vehicle trips, vehicle miles traveled (VMT), and emissions (CDC-Transportation recommendation, RAND-Sorenson 2008, , , ), and may be a cost effective strategy to reduce greenhouse gas emissions (). Public transportation systems produce significantly fewer emissions per passenger mile than private vehicles, especially when operating with full passenger loads (US DOT-FTA Transit and climate).

Incentive programs may increase transportation revenue (RAND-Sorenson 2008), reduce transportation costs for employers and individuals (RAND-Sorenson 2008, ), and cost less than providing parking spaces for commuters (Lari 2014, Shoup 2004).

Public transportation (bus, rail, and general transit) accounted for 0.4% of transportation fatalities in 2015 (US DOT-BTS Fatalities).

Impact on Disparities

No impact on disparities likely

Implementation Examples

The federal government has a transportation subsidy program in place for any federal employee in the National Capital Region that uses public transportation to commute to work (US DOT-TRANServe). Some states (e.g., Oregon) award energy tax credits to businesses or organizations that offer financial incentives to encourage employees to use public transportation or alternatives to single occupancy vehicles for their commutes (ODOE-Transportation). Municipalities can adopt transportation management plans that include incentives to encourage public transportation use, walking, or bicycling, and reduce single occupancy vehicle use, as in the City of Alexandria, Virginia (Alexandria-TMPs) or use a Transportation Management Association (TMA), as in Sacramento, California (Yolo-TMA).

Other individual incentives, such as transit pass incentive programs for employers, students, and state or city employees are available in many municipalities, including Austin, Texas; Seattle and Olympia, Washington; Monroe County, Pennsylvania; Nashville, Tennessee; and Portland, Oregon (TRB-Boyle 2010).
