DISAGGREGATE STOCHASTIC MODELS OF TRAVEL-MODE CHOICE

Abstract

THIS PAPER IS CONCERNED PRIMARILY WITH IDENTIFYING THE RESEARCH AND DEVELOPMENT NEEDED TO BUILD GENERAL MODELS OF MODE CHOICE THAT ARE BASED ON THE MODELING OF INDIVIDUAL BEHAVIOR. THE EXISTING AGGREGATE ASSOCIATIVE MODELS ARE DISCUSSED IN GENERAL TERMS, AND THEIR SHORTCOMINGS ARE IDENTIFIED. THE RATIONALE OF DISAGGREGATE BEHAVIORAL MODELS IS THEN PUT FORWARD, AND THE POTENTIALS OF SUCH A MODELING TECHNIQUE ARE DISCUSSED. IN THIS DISCUSSION, THE PRESENT STATE OF DEVELOPMENT OF BEHAVIORAL DISAGGREGATE MODELS IS INDICATED. BASED ON PRESENT EXPERIENCE IN BUILDING THESE MODELS, A SET OF RESEARCH AND DEVELOPMENT TASKS IS IDENTIFIED AS BEING NEEDED TO DEVELOP MORE GENERAL OPERATIONAL MODELS OF THIS TYPE. AS EACH TASK IS IDENTIFIED, SUGGESTED MEANS OF RESEARCH ARE PUT FORWARD. /AUTHOR/
