A ground marking apparatus is configured to apply marking material to a ground surface. The ground marking apparatus includes a beam supported by a beam mount and extending along a beam axis. A carriage is disposed on the beam and movable on the beam along the beam axis. A carriage motor operably interfaces with the beam and is configured to move the carriage along the beam. A dispense arm is supported by the carriage and is configured to move relative to the beam as the carriage moves along the beam.

A soil compactor for compacting soil material, in particular asphalt, comprises at least one compactor roller (14, 16) which is rotatable on a compactor structure (30) around a roller axis of rotation (W) which is essentially orthogonal to a compactor longitudinal direction (L) and at least one marking unit (26, 26) carried on the compactor structure (30) for applying marking material (M) to soil material (12) driven over by the soil compactor (10).

Provided is a method for marking a ground surface according to a predefined marking pattern using a system including a robot unit and a local base station including acts of providing two flag points, receiving global positioning data of the robot unit using a robot GNSS receiver, receiving global positioning data of the local base station using a base GNSS receiver, and establishing a local base station position using the received global positioning data of the local base station. A method wherein the predefined marking pattern is arranged relative to the two flag point positions and wherein the local base station position is a system reference point of the system. Also provided is a system for marking a ground surface according to a predefined marking pattern and the use thereof or parts thereof.

Disclosed herein are methods and systems for detecting dynamic objects using road painted patterns perceptible in infrared spectral range, comprising receiving images captured in one or more infrared spectral ranges depicting a road segment painted with background patterns which are highly imperceptible in visible light spectrum while highly visible in one or more infrared spectral ranges, analyzing the images to detecting one or more dynamic objects located in front of the background patterns. The light reflected by the one or more dynamic objects in the one or more infrared spectral ranges deviating from the light reflected by the one or more background pattern and computing a location of the one or more identified objects. Further disclosed are methods and systems for calibration of systems and/or sensors based on reference markings which are highly imperceptible in visible light spectrum while highly visible in the infrared spectral range(s).

A control system for positioning a marker over a pre-existing roadway surface mark. The control system has an electromagnetic radiation source attached to the marker for producing a mark pattern on the roadway surface. An imager permits the control system to image both the pre-existing roadway surface mark and the mark pattern produced by the electromagnetic radiation source. A computer is responsive to the imager for producing an error signal based upon the location difference between (a) the image of the pre-existing roadway surface mark and (b) the image of the mark pattern produced by the electromagnetic radiation source. An actuator is responsive to the error signal for positioning the marker over the pre-existing roadway mark.

A method or applying a fast curing epoxy traffic marking composition is provided in which curing agents are coated on a carrier such as glass beads or porous silica. These carriers are dropped onto the epoxy coating and promote rapid curing of the top layer of the epoxy coating while the bottom layer is given additional time to adhere to the roadway surface.
