Extending the theory of planned behavior: The role of behavioral options and additional factors in predicting speed behavior
M Cristea, F Paran, P Delhomme - … Research Part F: Traffic Psychology and …, 2013 - Elsevier
The theory of planned behavior (TPB) has been successfully predicting behavior with a
small number of factors. Nonetheless, to increase its predictive power we introduced several
behavioral options and additional factors in the same prediction model about drivers' self-
reported speed behavior on a road with a speed limit of 90 km/h. We investigated the TPB
factors as well as descriptive norms, perceived similarity with/description of the prototypical
driver, and past behavior with respect to three speed options (⩽ 90 km/h;[91− 110 km/h];+ …
