Separation of Car-Dependent Commuters from Normal-Choice Riders in Mode-Choice Analysis

Most metropolitan governments are attempting, with limited success thus far, to discourage the use of cars. It is well known that normal-choice riders choose their travel mode based on utility, which is determined by mode-specific impedances and individual characteristics. This study focuses on identifying car-dependent commuters who tend to keep driving cars regardless of the circumstances they are confronted with. Psychometric factors characterizing car-dependent commuters were investigated. The performance of the mode-choice model was not sufficiently enhanced despite incorporation of the psychometric factors. Based on psychometric factors, the support vector machine successfully separated the car-dependent commuters from normal-choice riders. The performance of the model was found to improve considerably when the car-dependent commuters were excluded.
