In 1910, nine European countries settled on a common symbol, using images for road signs to indicate blows, curves, intersections and railroad crossings. During the following decades, intensive work in signaling research and development culminated in the development of the European Signaling System. With the turn of the century, as the volumes of vehicles and traffic increased and night driving progressed significantly, the flat painted signs gave way to the signage with raised letters and later to the signs and reflectors so that the drivers could See the signs at night.
