BARRERO, Lope Hugo et al. Pedestrians' Beliefs about Road Crossing in Bogotá: Questionnaire Development. Univ. Psychol. [online]. 2013, vol.12, n.2, pp.433-444. ISSN 1657-9267.

Understanding the pedestrian choices is essential for the design of safe road systems. This study develops methods for self-reported assessment of pedestrian behavior. A self-report instrument was developed to investigate the Theory of Planned Behavior (TPB) constructs in relation to pedestrians' road crossing using a convenient sample. Internal consistency and factor analysis were conducted to test the reliability and construct validity of the instrument. Self-reported intention to execute risky behavior was compared with observed behaviors. The developed questionnaire showed high internal consistency for most of the TPB constructs (Chronbach's alpha>0.7). Factor analyses confirmed that questions grouped in constructs, as hypothesized. Pedestrians' intention to execute risky behavior was related to pedestrians' perceived physical capability and to the simultaneous crossing of other pedestrians. However, this intention correlated moderately with observed risky behavior (R_s = 0.35). The potential to understand the mechanisms of pedestrian choices using the developed instrument are considered exploratory, yet promising.
