摘要：AbstractThe aim of the present research was to examine whether an individuaĺs attitude towards cycling influences his perception of barriers (perceived behavioral control) for cycle commuting. Attitudes and perceived behavioral control were measured using psychological constructs, following the Theory of Planned Behavior. Data collection for this research was conducted in a public college in a Brazilian medium-sized city. The results indicate that the respondents have a positive attitude to cycling for four aspects: environmental benefits, health benefits, economy and feeling of independence. For other eight aspects (better observing the landscape, parking, speed, prestige, effort, risk of accidents, risk of being assaulted and exposure to sun and rain) the general attitude is negative. Perceived behavioral control (barriers) was assessed in relation to six possible obstacles to cycling: lack of infrastructure, lack of safety, distance, skill, slopes and climate. The main deterrent against cycling was lack of adequate cycling infrastructure. Lack of safety (which is associated with the absence of infrastructure) and slopes are other strong obstacles for commuting by bicycle in the city. Individuals who have a negative or neutral attitude toward cycle commuting are not very different in their perception of barriers for cycling. The individuals who have a positive attitude perceive weaker barriers (they have stronger behavioral control). In contrast, a very negative attitude is associated with the perception of stronger barriers.
