We propose a novel quantity-based travel demand management system aiming to promote ride-share. The system sells the permit to access a road facility (simplified as a bottleneck) by auction but encourages travelers to share the permits with each other through ride-share. The permit is classified according to access time and the travelers may be assigned one of the three roles: solo driver, ride-share driver, or rider. At the core of this auction-based permit allocation and sharing system (A-PASS) is a trilateral matching problem (TMP) that optimally matches the permits, drivers and riders with one another. We formulate the TMP as an integer program, and proved it can be reduced to an equivalent linear program. A pricing policy based on the classical VCG mechanism is proposed to determine the payment for each traveler. We also show the operator of A-PASS can eliminate any deficit that may arise from the application of the VCG mechanism, by controlling the number of shared rides. Results of numerical experiment suggest the trilateral matching scheme strongly promote rider-share. As ride-share increases, all stakeholders are better off: the operator receives greater profits, the commuters enjoy higher utility, and the society benefits from more efficient utilization of infrastructure.
