How does the inclination to bicycle sway the decision to ride in warm and winter seasons?

ABSTRACT Many cities are creating policies and programs aimed at expanding bicycling mode shares. Attitudes towards bicycling in combination with weather conditions, however, can strongly influence the decision to ride. In locations with wide annual seasonal variation, attitudes can radically alter demand on bicycle networks across the year. Though researchers have looked at weather impacts on bicycling, the link between attitudinal factors that might impact riding decisions and seasonal variation remains understudied. This paper investigates heterogeneous taste preferences about the inclination to bicycle for riders who ride only in the warm weather and those who ride all year long (including during severe winters). This research relies on survey data from Edmonton, Canada and presents results from a hybrid discrete choice model. After controlling for age, sex, education, income, the supply of bike lanes, and the latent variable “bicycling inclination,” the results indicate that attitudes have a significantly positive impact on the decision to ride across seasons. The findings suggest that public education and season-specific training programs—particularly aimed at adults and women—have the potential to increase bicycling all year around.
