Factors Influencing Demand for Buses Powered by Alternative Energy Sources
Journal of Public Transportation
Transit buses consume high amounts of fossil fuels, with the consequent release of greenhouse gases into the atmosphere. In recent decades, much effort has been concentrated on the development of cleaner fuels to mitigate this externality. However, market shares for cleaner-fueled buses are still modest, which is why it is relevant to evaluate the aspects influencing their acceptance. This article presents an econometric model to evaluate factors influencing demand for transit buses in Colombia
... t buses in Colombia powered by cleaner fuels. For this purpose, a stated preference survey was applied to public transportation entrepreneurs. Results suggest that the target population considers acquisition cost and operating cost as the most important variables when choosing fuel technology for their fleets. The power offered by the bus engine was relevant for some alternative fuel alternatives, but not the full range. by alternative fuel technologies was calibrated using data gathered from Colombian transit entrepreneurs and following the discrete choice modeling approach. Discrete choice models are widely used in demand studies and consumer behavior analysis because they allow the forecasting of market shares for real or hypothetical alternatives. Observed decisions and information about attributes describing technological alternatives (i.e., commonly collected through revealed or stated preference surveys) are used to calibrate the models and, consequently, to analyze the importance of attributes in the choice decision process. This paper is structured as follows: in the next two sections previous studies related to the research topic are reviewed and the context of public transportation in Colombia is explained. Then, the methodological approach used is presented. After that, a complete description of the data and the main results are shown. Finally, the most relevant conclusions and guidelines for future research are listed.
