A MODEL FOR THE STUDY OF MODAL CHOICE IN INTER-URBAN TRAVEL

A MODEL IS DESCRIBED WHICH HAS BEEN DEVELOPED TO PREDICT MARKET SHARES OF TRAFFIC FLOW ON EACH MODE OVER A MULTI-MODAL INTER-CITY NETWORK. THE PRESENT STATUS OF THE WORK IS THAT A MODAL SPLIT MODEL EXISTS WHICH WILL ALLOCATE A GIVEN NUMBER OF PEOPLE TRAVELLING BETWEEN A PAIR OF ZONES TO THE VARIOUS LINKS BETWEEN THE TWO CITIES AND WHICH TAKES SOME GENERATION EFFECTS INTO ACCOUNT. THE MODEL IS GEOGRAPHICALLY SPECIFIC, I.E. IT DOES NOT ATTEMPT TO PREDICT THE FORM OF A CITY WITH ITS DISTRIBUTION OF ORIGINS, DESTINATIONS, AND MAIN MODE TERMINALS, BUT USES DATA FROM REAL CITIES. THE MAIN FEATURE OF THE MODEL IS THAT IT TAKES INTO ACCOUNT THE TERMINAL JOURNEYS BY CONSIDERING THE AVAILABLE ROUTES FROM ORIGIN TO DESTINATION AS BEING A COMBINATION OF ACCESS, MAIN, AND EGRESS MODES. MONEY COSTS, TOGETHER WITH TRAVEL AND WAITING TIME PENALTIES, ARE INCURRED AT EACH STAGE, RESULTING IN AN OVERALL COST AND JOURNEY TIME FOR THE JOURNEY, FURTHER DEVELOPMENT TO ALLOW INTER-MODE INTERCHANGES AND TO FORECAST TOTAL NUMBERS OF JOURNEYS WILL CONTINUE. /TRRL/
