Abstract: A device is provided for automatic re-striping of horizontal road markings and which can be mounted on a vehicle. In one embodiment the device comprises a marker unit with a linear actuator, an electronic control unit electrically connected to the linear actuator, wherein the electronic control unit comprises an electronic gyroscope which can determine an angular speed of the vehicle on curved road sections, and a laser scanner mounted in front of the marker unit. In some embodiments the electronic control unit is configured to calculate and offset, based on the angular speed of the vehicle, for additional deviation of the paint guns from the coordinates of any of the previous marking lines when the vehicle moves on curved road sections.
