Using the Theory of Planned Behavior to Explain Cycling Behavior

Latin American cities are facing crucial changes to become cycling cities. To develop effective policies in this regard, it is essential to understand the factors influencing bicycle commuting. The Theory of Planned Behavior —tpb— (Ajzen 1991) has provided a useful model to explain travel mode choice. The present study tested the tpb within the domain of bicycle mode choice with 172 participants from Buenos Aires, Argentina. Data was modeled using path analysis. The tpb model displayed an excellent fit. Results showed that intention predicted 53% of the variance in cycling to university. In addition, tpb variables (attitude, subjective norm, and perceived behavioral control) predicted 59% of the intention to use the bicycle to commute to university. The study also discusses the theoretical and practical implications for promoting bicycle use.Keywords: Theory of Planned Behavior, bicycling behavior, active transportation.
