Researchers in the transportation field have long been discussing the use of single occupancy vehicles and its negative externalities (congestion, pollution, parking demand, etc.). We contribute to this area with a recent article with a focus on carpooling .
While carpool formation require both a driver and at least one passenger, there has been a lack of studies that explore role preferences (driver versus passenger) and their implications. Based on individuals’ stated interests and revealed choices, we identify three market segments: current carpool users, potential carpool users, and not-interested commuters. Our study shows that the incentives and deterrents for carpooling significantly differ by role preference and carpool market segment. The findings from our comparative analysis and statistical modeling indicate that there are opportunities to increase carpool use through focusing on interested individuals and specific incentives for each carpool role.
