ABSTRACT:
A system for effecting merging of a first vehicle traveling in a first roadway with successive vehicles traveling in a second roadway, said system including: a sensor capable of detecting the movement of the successive vehicles in the second roadway; conversion means for determining from the detected movement when the distance between the successive vehicles permits merging; and a road-marking arrangement for producing a guidance light visible to at least the first vehicle and seemingly moving with the two successive vehicles, the light indicating when said merging is permitted. The dynamic road marking system enables higher traffic intensities on roadways and improved traffic safety.
