The road-marking system for influencing the distance between vehicles ( 6, 6 ', . . . ) traveling over a roadway ( 10 ) comprises: a plurality of road-marking units ( 3; 3', 3'', . . . ; 4, 4 ', . . . ), the road-marking units being provided with light means for emitting or reflecting light in the direction of a driver of the vehicle ( 6, 6 ', . . . ). In operation, a set of the road-marking units ( 4, 4 ', . . . ) is in an active state, while the remainder of the road-marking units ( 3; 3', 3 '', . . . ) is in an inactive state. The distance between the active road-marking units ( 4, 4 ', . . . ) in the set is indicative of the desired distance between the vehicles ( 6, 6 ', . . . ). Preferably, the light emitted or reflected by the set of active road-marking units ( 4, 4 ', . . . ) is tuned in response to conditions during the day or during the night. |
