  1. Using Mobile Apps to Measure Spatial Travel Behavior Changes of Carsharing Users Sisinnio Concas, S. Barbeau, P.L. Winters, N.L. Georggi, J.M. Bond Center for Urban Transportation Research Session 765 Technology and Travel Surveys

  2. What is Carsharing? • Short-term auto rental option • Hourly flat rate • Annual membership fee • No gasoline costs • Unlimited mileage • No parking costs

  3. Carsharing Program • Launched at the University of South Florida, Tampa Campus, on July 2009 • Short-term rental option with hourly flat rate • Annual membership fee • Unlimited mileage • Non parking costs • No gasoline costs • Four hybrid vehicles available 24/7

  4. Program Participation

  5. Tracking Spatial Behavior “This is my trip to campus, via the Bull Runner, to pick up the WeCar. I then drove the WeCar to the CVS on Fowler to pick up medication and then drove to the grocery store on Bears Ave. After shopping, I dropped the groceries off at home and then drove back to campus to return the WeCar. I then took the Bull Runner back home.”

  6. Communicating with Users

  7. Trips by Mode and Purpose

  8. Communicating Pricing Changes • Incentives to encourage off-peak travel • 50-percent reduction in hourly rates • Rate changes communicated by email to treatment: • Scheduling constraints accounted for • Discount applied on actual rental starting time

  10. Rental Cost and Rental Time Before Variable Pricing After Variable Pricing

  11. Discussion (1) • User interaction and real-time data monitoring contributed to continued participation throughout the study. • Participants responded positively to this interaction and expressed a sense of confidence in the GPS tracking tool. • Data collection allowed studying users’ travel behavior responses to variable pricing experiments.

  12. Discussion (2) • The research examined changes in travel behavior through pricing mechanisms based on time-of-day and day-of-week hourly rate discounts. • The study found that overall carsharing users are price sensitive • Changes in rental rates of the order of 20 to 50 percent have a significantly large impact on daily rentals. • The analysis shows that carsharing users’ activity space contracts while using carsharing as a mode of transport.
