Modeling mode choice behaviors of commuters in car-dependent small country discrete choice models: A case study of Bahrain
The aim of this study is to determine the factor affecting the mode choice of travelers in Bahrain, which presents a unique case due to its smaller area size and current dependence on cars. Hence, the need for promoting sustainable modes of transportation is critical for the country. The study used 3864 diverse data records extracted from traveler surveys. This data comprised of revealed preference responses. The variables considered in the modelling included traveler characteristics, and trip information. The logit model and the classification tree models were used to predict the mode choice, considering the currently available modes of transportation currently available (Car and Bus). The accuracy of the models was ascertained through a validation sample collected independently from the initial sample. Trip cost was the most influential factor on mode choice. Other important variables included direct and quick travel, accessibility, and convenience. In terms of model performance, the logit model demonstrated higher accuracy than the classification tree when modeling binary responses. The models and results of this study provide important conclusions for the transportation authorities, which can be utilized for developing and promoting sustainable transportation modes in Bahrain.
