FARIA, Bruno Araújo and KAMIZAKI, Ricardo. Discrimination of vehicle speeds by stationary observers. Psicol. pesq. [online]. 2020, vol.14, n.spe, pp.170-185. ISSN 1982-1247. https://doi.org/10.34019/1982-1247.2020.v14.30399.
The perception of movement is an object of study of psychophysics, however there are few studies in naturalistic situations or using real vehicles. We investigated how people perceive vehicle speed in natural situations. Static observers were asked to determine the speed of a real moving vehicle. The results showed accuracy in the estimates of vehicle speeds, regardless of the participant's gender and whether or not they are licensed. The exponent of the power-function associated with this dimension was 1.31, showing a tendency to overestimate with increasing physical speed, indicating that there is no linearity in the perception of vehicle speeds by static observers
