Abstract |
Various factors can influence the choice of transportation mode such as the urban layout, land use and occupation patterns, and the services offer. In recent years, however, research studies have investigated the influence of psychological aspects on personal decision-making associated to modal choice, thereby contributing towards the elaboration of more sustainable public policies. This study investigates the beliefs that are subjacent to modal choices regarding school commute trips, based on the opinions of students attending a senior high school institution in Brasilia, Brazil. Using procedures suggested by the Theory of Planned Behavior (TPB) a set of beliefs was obtained by means of a focus group activity and used to support the elaboration of a School Trips Modal Choice Scale (STMCS). The scale was subjected to Principal Components Analysis to verify the consistency of factors related to the beliefs and the direct measurements of the TPB constructs. Following that Generalized Linear Models (GLM) were elaborated using the Quasi-likelihood estimation method to investigate the correlation between the beliefs obtained and the said constructs. In addition to identifying the principal beliefs related to the modal choice, the results showed that different TPB constructs can be correlated with the same belief and so attributing specific beliefs to each construct based on an initial intuitive classification can actually be an impediment to understanding them. Those findings regarding the beliefs identified as subjacent to each construct are specific for the school community that was studied. However the question of some beliefs significantly affecting more than one construct is a more generalizable and corroborates what has previously been verified in other contexts where TPB has been applied.
