Potential of Carpooling among Unfamiliar Users: Case of Undergraduate Students at Istanbul Technical University

Abstract

This paper analyzes the passenger-carpooling potential among undergraduate students using a model for estimating choice based on combined revealed and stated preference data. The data are obtained from a survey performed at four campuses of Istanbul Technical University. The case in focus is carpooling as a passenger; carpooling as a driver is deliberately left out because of students’ lack of familiarity with it. The hypothetical passenger-carpooling scenarios lead to enquiries about the fee students are willing to pay and the distance they are willing to walk to a designated pick-up location. The estimation results show that females and frequent campus travelers are more likely to prefer passenger carpooling. The scenario analysis included in the paper reveals the prioritization of carpool fee over walking distance to pick-up locations among undergraduate students.
