WORK TRIP DISTRIBUTION AND MODAL SPLIT IN THE METROPOLITAN TORONTO REGION

THE PURPOSE WAS TO REFINE EXISTING TRIP DISTRIBUTION AND POST-DISTRIBUTION MODAL SPLIT MODELS IN AN ATTEMPT TO OVERCOME DEFICIENCIES ARISING FROM: (1) THE OPERATION OF THE MODELS AT THE AGGREGATE OR TOTAL PERSON TRIP LEVEL, (2) THE USE OF TRAVEL TIME FACTOR FUNCTIONS CALIBRATED TO BASE YEAR CONDITIONS, AND (3) THE DEPENDENCE OF MODAL SPLIT MODELS ON FORECASTS OF RELATIVELY DETAILED SOCIO-ECONOMIC DATA. A UNIFIED TRIP DISTRIBUTION MODEL IS PROPOSED WHICH INCORPORATES: (1) A FUNCTION WHICH ALLOWS JOURNEY TO WORK TRIP ENDS TO BE SPLIT INTO CAPTIVE AND NON-CAPTIVE TRIP-MAKERS BASED ON EMPLOYMENT AND DWELLING UNIT OPPORTUNITIES, (2) THE DIRECT ESTIMATION OF THE FUTURE TRAVEL TIME FACTOR FUNCTION, AND (3) AN ESTIMATION OF THE FUTURE MODAL SPLIT TRAVEL TIME FACTOR FUNCTIONS BASED ON FAIRLY SUPERFICIAL KNOWLEDGE OF LAND USE AND TRANSPORT CHARACTERISTICS. THE MODEL WAS CALIBRATED WITH THE 1964 METROPOLITAN TORONTO AND REGION TRANSPORTATION STUDY DATA. COMPARISON OF THE SIMULATED AND OBSERVED TRAVEL DEMAND PATTERNS INDICATED THAT THE MODEL IS VALID. THE UNDERLYING CONCEPTS OF THE MODEL CAN BE USED DIRECTLY FOR THE CALIBRATION OF CERTAIN TYPES OF URBAN LAND USE MODELS. /RATAOC/
