EFFICIENCY OF MULTIMODAL TRANSPORT WITH EMPHASIS ON INTERMODAL TRANSFER

MATHEMATICAL MODELS ARE DESCRIBED WHICH HAVE BEEN DEVELOPED AND EXERCISED ON A DIGITAL COMPUTER TO SIMULATE THE ORIGIN AND DESTINATION CHARACTERISTICS OF MULTIMODAL TRIPS, WITH PARTICULAR EMPHASIS ON INTERMODAL TRANSFER AND FUNCTIONAL OPERATIONS OF THE TERMINALS AND NODES ASSOCIATED WITH SUCH TRANSFER. THE RESEARCH WAS BROKEN OUT INTO FOUR AREAS. THE FIRST IS A REFINED CONCEPTUAL MODEL OF THE O&D TRAVEL PROCESS FOR A MULTI-MODAL TRIP, IN WHICH WAITING TIME IS DIVIDED INTO TRAVEL-RELATED TIME AND SLACK TIME. IN THE SECOND, PASSENGER TRAVEL WAS FORMULATED MATHEMATICALLY SO AS TO RELATE THE TWO TYPES OF WAITING TIME AND MINIMIZE NECESSARY WAITING TIME FOR THE CASE OF TRANSFER BETWEEN TWO SCHEDULED MODES. IN THE THIRD, A STOCHASTIC PROCESS WAS ASSUMED FOR UNSCHEDULED ARRIVALS (AUTOMOBILE) AND SCHEDULED DEPARTURES. THE FOURTH STUDY AREA EXAMINED CHARACTERISTIC SERVICE QUEUES AT TERMINALS. THE SECOND AREA SUFFERED FROM BEING DETERMINISTICALLY FORMULATED AND FROM THE DIFFICULTY OF FORMULATING COST CONSTRAINTS. MODELS IN THE THIRD AND FOURTH AREAS WERE SUCCESSFULLY EMPLOYED IN COMPUTER SIMULATIONS.
