Abstract
THIS PAPER DEVELOPS A CAR-BUS MODAL SPLIT MODEL FOR AN ISRAELI SAMPLE WHICH DIFFERS FROM MOST PREVIOUS MODAL SPLIT MODELS IN TWO RESPECTS: (1) THE UNCERTAINTY OF COMMUTERS REGARDING THE DIFFERENCE IN TIME COST BETWEEN THE TWO MODES IS TAKEN INTO ACCOUNT, AND (2) THE DEPENDENT VARIABLE IS CONTINUOUS RATHER THAN DICHOTOMOUS. THE RESULTS SUGGEST THAT UNCERTAINTY IS INDEED AN IMPORTANT ELEMENT IN MODAL CHOICE, AND THAT CONTINUOUS MODAL SPLIT MODELS CAN ACHIEVE HIGHER LEVELS OF STATISTICAL EXPLANATION THAN BINOMIAL OR MULTINOMIAL MODELS.(Author/publisher).
