Recently, shared mode alternatives (e.g. carpooling, carsharing, express minibus and shared taxi) have re-emerged as possible options to enhance mobility efficiency in urban areas. With this paper the authors were able to develop and calibrate a discrete choice model that integrated the traditional transport options (e.g. private car, motorcycle, bus, metro, mode combinations), with the new shared mode alternatives. The authors then used the developed model to estimate potential mode shares of the new alternatives through a Monte-Carlo simulation. The model was obtained through the joint calibration of revealed and stated preferences data obtained from a specifically designed mobility survey at the Lisbon Metropolitan Area. It also incorporates attitudinal traits that showed significant impact on the new shared transport alternatives. The obtained results presented some insightful views of the trade-offs between alternatives and on some aspects that should be dealt with, when introducing these new transport options in the mobility market. The new transport alternatives also seem to present potential to have some effect on urban mobility systems.
