1. A road-marking system comprising:at least a first ( 1 ) and a second road-marking unit ( 2 ) each having an emission surface ( 10 ; 20 ), the first unit ( 1 ) comprising a first light source ( 21 , 21 ′ . . . ) and the second unit ( 2 ) comprising a second light source ( 22 , 22 ′ . . . ),characterized in that each unit ( 1 ; 2 ) has a shape adapted to a saw-cut recess ( 9 ) for accommodating the unit ( 1 ; 2 )wherein at least one of the light sources comprise an optoelectronic element comprisinga light-emitting diode ( 21 , 21 ′ . . . ), anda collimator ( 33 , 33 ′ . . . ) for collimating light from the light-emitting diode and for directing the light through an opening ( 39 , 39 ′ . . . ) in the emission surface ( 10 ). 2. A road-marking system as claimed in claim 1, characterized in that the recess ( 9 ) for accommodating the unit ( 1 ; 2 ) has a cylindrical bottom part in the shape of circular segment. 3. A road-marking system as claimed in claim 1 or 2, characterized in that the recess ( 9 ) for accommodating the unit ( 1 ; 2 ) is obtainable by a saw-cut or by a saw-cut in combination with a drill-hole. 4. A road-marking system comprising:at least a first ( 1 ) and a second road-marking unit ( 2 ) each having an emission surface ( 10 ; 20 ), the first unit ( 1 ) comprising a first light source ( 21 , 21 ′ . . . ) and the second unit ( 2 ) comprising a second light source ( 22 , 22 ′ . . . ),characterized in that each unit ( 1 ; 2 ) has a shape adapted to a saw-cut recess ( 9 ) for accommodating the unit ( 1 ; 2 )characterized in that, during normal operation of the system, light beams originating from the first ( 21 , 21 ′ . . . ) and the second light source ( 22 , 22 ′ . . . ) and appearing at the emission surface ( 10 ; 20 ) of the respective unit ( 1 ; 2 ) overlap each other at a distance ≧40 m from the first light source in a plane which encloses an angle α, 0.1°<α≦8°, with a line L which interconnects the first and the second light source. 5. A road-marking system as claimed in claim 1 or 2, characterized in that the road marking unit ( 1 ; 2 ) comprises at least one stabilizer ( 23 ; 24 ) at least adjacent to the emission surface ( 10 ; 20 ). 6. A road-marking system as claimed in claim 5, characterized in that the stabilizer ( 23 ; 24 ) comprises at least one duct ( 25 ) at least substantially parallel to the line L for the passage of electrical/optical cables ( 26 ). 7.

A road-marking system as claimed in claim 7, characterized in that the distance d lies in a range from 15 to 20 cm. 9. A road-marking unit ( 1 ) for use in a road-marking system as claimed in claim 1 or 2, comprising an emission surface ( 10 ) and a light source ( 21 , 21 ′ . . . ), at which unit light beams issue from its emission surface ( 10 ), during normal operation,characterized in that said unit ( 1 ) has a shape adapted to a recess ( 9 ) for accommodating the unit ( 1 ), the recess being obtainable by a saw-cut or by a saw-cut in combination with a drill-holewherein at least one of the light sources comprise an optoelectronic element comprisinga light-emitting diode ( 21 , 21 ′ . . . ), anda collimator ( 33 , 33 ′ . . . ) for collimating light from the light-emitting diode and for directing the light through an opening ( 39 , 39 ′ . . . ) in the emission surface ( 10 ). 10. A road surface R provided with a road-marking system as claimed in claim 1 or 2 or 4 or at least two road-marking units ( 1 ) as claimed in claim 9. 11. A complex for marking roads comprising one or more road-marking systems as claimed in claim 1 or 2 or 4 , a control system for the road-marking systems, and means for coupling the road-marking systems to the control system. 12. A road-marking system as claimed in claim 3, characterized in that, during normal operation of the system, light beams originating from the first ( 21 , 21 ′ . . . ) and the second light source ( 22 , 22 ′ . . . ) and appearing at the emission surface ( 10 ; 20 ) off the respective unit ( 1 ; 2 ) overlap each other at a distance ≧40 m from the first light source in a plane which encloses an angle α, 0.1°≦α≦8°, with a line L which interconnects the first and the second light source.
