Road sign sensing system

摘要

In a road sign sensing system, a digital signal sign for intoning a vehicle driver of a road sign (4, 5, 9, 10, 41) indicative of the digital signal sign includes a plurality of bars (11 to 18, 19 to 26, 19' to 25') provided on a road surface as extended in a direction perpendicular to a vehicle running direction. Camera sensors (120, 122, 124, 126) for scanning and reading the digital signal sign are mounted on the vehicle so that scanning lines of the sensors are perpendicular to the plurality of bars.
