ESTIMATING AUTO OCCUPANCY: A REVIEW OF METHODOLOGY

IF URBAN TRANSPORTATION PLANNING IS TO MAINTAIN ITS RELEVANCY, IT WILL BE NECESSARY TO REVIEW CONTINUALLY THE DEGREE TO WHICH THE PROCEDURES AND MODELS USED IN PLANNING KEEP PACE WITH CHANGING POLICY ISSUES. IT NOW APPEARS THAT THE RISING DOLLAR AND SOCIAL COSTS OF PROVIDING HIGHWAYS AND PARKING IN URBAN AREAS ARE HAVING AN IMPACT AT THE POLICY LEVEL. SERIOUS CONSIDERATION IS BEING GIVEN TO ALTERNATIVES THAT INCREASE AUTO OCCUPANCY, SUCH AS PROVIDING PREFERENTIAL LANES FOR CARPOOLS; LEASING VANS FOR CARPOOLS; AND TAXING, REGULATING, OR REDUCING DOWNTOWN PARKING. THUS, AUTO OCCUPANCY MODELS ARE BECOMING RECOGNIZED AS POTENTIALLY VALUABLE ANALYSIS TOOLS IN THEIR OWN RIGHT RATHER THAN ONLY AS A STEP IN THE MODAL SPLIT SEQUENCE. FOUR METHODS FOR DEVELOPING THE MODELS ARE DISCUSSED WITH EXAMPLES BEING CITED IN THE APPENDIX FROM 11 CITIES-AVERAGE FACTOR, CURVE FITTING, CROSS CLASSIFICATION, AND REGRESSION ANALYSIS.
