Abstract

This study focused on the effects of median type on drivers' subjective sense of speed and the changes in this sense by driver age. Participants were 61 drivers: 20 young (aged 20-39 years), 19 middle-aged (40-59 years), and 22 older drivers (60+ years). The participants watched each of two driving scenarios, showing either a guardrail-equipped or a concrete median. The participants were asked to push a button when they perceived speeds of 60 km/h, 80 km/h, or 100 km/h. All drivers perceived higher speeds in the guardrail condition than in the concrete condition. Perceived speeds increased with driver age in both guardrail and concrete conditions. These results mean median type affects drivers' subjective sense of speed even as driver age increases, and that drivers' subjective sense of speed tends to increase with age.
