Abstract
This study describes the reading time to contents of simple graphic display, especially traffic congestion information of ordinary roads via FM multiple broadcasting while stopping and driving. Elderly and young drivers participated in the experiment using simulated contents of the simple graphic display and a driving simulator. The reading time to the contents, vehicle behavior and subjective workload were measured based on the density of roads and the number of arrow marks indicating traffic congestion of the content during both driving and stopping condition. Based on those results, the reading time was compared and discussed between elderly and young drivers.
