INVESTIGATION OF MODAL CHOICE FOR DUAL-MODE TRANSIT

The attitudes of individuals regarding dual-mode transit, personal rapid transit, and people-mover forms of urban transportation were collected through a home-interview survey. It was hypothesized that a more thorough understanding of mode choice could be obtained by stratifying the sample into homogeneous groups rather than by considering the set of respondents collectively. Respondents were grouped according to two alternative criteria: socioeconomic characteristics and preference judgements. A multivariate clustering procedure was used to determine groups. Frequently used variables for defining socioeconomic groups were income, age, education, and race. Of the 12 system attributes, those selected most often to define preference groups were temperature control, automatic control, and vehicle privacy. However, socioeconomic groupings were stratified by a more consistent set of variables than the preference groups. Mode choice was examined through the use of linear additive models. The predictor set for socioeconomic and preference groupings was composed of mode-dependent satisfaction judgements.These judments were made with respect to system characteristics such as waiting time, comfort, and accessibility. The variability of mode-choice judgments was accounted for more accurately by models that stratified individuals into homogeneous population segments than by modes that totally disaggregated individuals; this confirms the main hypothesis. Also, it was possible to account for a greater percentage of the mode choices with stratification by socioeconomic characteristics than by preference judgements of respondents. In general, the socioeconomic and preference groups used alternative predicator sets to explain their mode choices. Dual-mode transit was preferred to either personal rapid transit or people movers. /Author/
