Map Design: An On-the Road Evaluation of the Time to Read Electronic NavigationDisplays

摘要

This report covers the third of four experiments examining the time to readelectronic maps while driving. Three factors were varied: (1) the number of streets displayed (12 street and 24 street maps), (2) the street label text size (10, 12, and 14 point), and (3) the time of day (day vs. night driving). Sixteen drivers (ages 18-30 and > 65, both men and women) drove a test vehicle on public roads. Subjects were given three tasks while driving: (1) find the name of the street being driven, (2) find the name of a cross street ahead, and (3) find the location of a particular street on the map.
