A passenger-to-driver matching model for commuter carpooling: Case study and sensitivity analysis

•A passenger-to-driver matching model for commuter carpooling was initially proposed.•38.3% of trips can successfully form carpooling trips and save fuel significantly.•The participant flexibilities can help matching performance, especially when participant rate in a lower level.•The optimal fee-sharing ratio is not the traditional half to half.•The disincentives seem to have a greater effect on carpooling choice than the incentives.
