The factors influencing the decision to bicycle are explored and unraveled to inform the development of appropriate and effective strategies to increase bicycling and promote the health of individuals and of the environment. The data used in the analysis were drawn from a survey of Texas bicyclists, and the study includes a comprehensive explanatory analysis of bicyclists and their bicycling habits. Various econometric models are used to evaluate the determinants of bicyclists' perception for safety and quality issues and the frequency of bicycling for commute and noncommute purposes. The results of the study indicate that the perceptions of the quality of bicycle facilities and safety from traffic crashes show significant variation depending on bicyclists' demographic and work characteristics and bicycle amenities and facilities on the commute route and at the workplace. Bicyclist demographics (gender, age, education level, commute distance), household demographics (number of automobiles, number of bicycles, number of children), residential location and season, bicycle amenities at work (bicycle racks, showers), bicyclist perceptions of the overall quality of bicycle facilities, and bicycle-use characteristics affect commute and noncommute bicycling frequency. These study results can assist in the development of informed policies to increase commute and noncommute bicycling, and the results highlight the ongoing need for detailed surveys to understand bicycling behavior.
