A NOTE ON THE ABILITY OF SOCIO-ECONOMIC VARIABLES TO EXPLAIN ATTITUDINAL BIAS TOWARD ALTERNATIVE TRAVEL MODES

THIS PAPER DISCUSSES THE USEFULNESS OF SOCIO-ECONOMIC VARIABLES AS INDICATORS OF TRAVELER BIAS TOWARD ALTERNATIVE MODES OF TRAVEL. AN INDEX OF BIAS TOWARD TRANSIT AND AUTO MODES IS CONSTRUCTED FOR EACH TRAVELER, BASED ON HIS REPORTED ATTITUDES TOWARD SELECTED CHARACTERISTICS OF EACH MODE. A SET OF 28 SOCIO-ECONOMIC VARIABLES DESCRIBING THE TRAVELER, HIS TRIP, AND HIS HOUSEHOLD IS THEN EXAMINED FOR STATISTICAL EFFECTIVENESS IN EXPLAINING THE VARIATION IN THIS INDEX. THE DATA ARE FITTED TO AN ANALYSIS OF VARIANCE MODEL USING A STEPWISE ALGORITHM IN WHICH VARIABLES ARE ENTERED IN ORDER OF THEIR EXPLANATORY POWER. RESULTS SUGGEST THAT SOCIO-ECONOMIC VARIABLES ARE NOT VERY EFFECTIVE IN EXPLAINING TRAVELER BIAS. NEVERTHELESS, THE MOST IMPORTANT PREDICTOR VARIABLES ARE DISCUSSED. IT IS SUGGESTED THAT TRAVELER ATTITUDES AND BEHAVIOR ARE JOINTLY DETERMINED AND TOGETHER FROM A CLOSE-KNIT COMPLEX. THE AGREEMENT OF TRAVELER ATTITUDES AND BEHAVIOR SEEMS TO INCREASE AS A RESULT OF PRIOR COMMITMENTS SUCH AS THE PURCHASE OF AN AUTOMOBILE. SEVERAL ALTERNATIVE TRIP CLASSIFICATION SCHEMES BASED ON THESE FINDINGS ARE DISCUSSED.
