An automatic and intelligent spraying device for traffic marking intelligent. The spraying device for traffic marking includes a fixed bottom plate, a coating storage tank, a control box provided with a controller, an armrest, a row of nozzles, a speed sensor, and a driving motor. The coating storage tank is connected with coating pipes equipped with an electromagnetic valve. The fixed bottom plate is provided with a driving motor and rotating wheels. The driving motor drives the rotating wheels to move. The speed sensor is electrically connected with the controller and the driving motor. The controller controls a speed of the driving motor according to speed information detected by the speed sensor. The controller controls the driving motor, and controls the row of nozzles to spray according to a preset spray marking and spray pattern through the electromagnetic valve.

This application provides an intelligent two-dimensional traffic marking spraying device, to reduce the construction amount of workers, improve the construction quality and the work efficiency. The intelligent two-dimensional traffic marking spraying device includes a baseplate, a coating storage tank, a control box, a armrest, a row of nozzles, a speed sensor, a drive motor and four rotary shafts. When spraying traffic marking, the builders first select the marking, then set the next base point, and turn on the main switch. The coating contained in the coating storage box enters into the nozzle and sprays out. Meanwhile, the solenoid valve opens and closes at the corresponding position through the feedback information of the speed sensor and the control of the controller, so as to achieve the purpose of spraying two-dimensional traffic marking.

Disclosed herein are methods and systems for painting driving markings invisible in visible light spectrum, comprising generating driving assistance markings expressing driving information relating to one or more road segments, computing instructions for painting the driving assistance markings on one or more elements of the road segment(s) using one or more paint material(s) characterized by: (1) reflecting light in a visible light spectral range deviating less than a first value from the visible light spectral range reflected by a surface of the element(s) and (2) reflecting light in an infrared spectral range deviating more than a second value from the infrared spectral range reflected by the surface of the element(s), and outputting the painting instructions for applying the one or more paint materials on the element(s) according to the instructions such that the driving assistance markings are visible in the infrared spectrum and significantly invisible in the visible spectrum.

Disclosed herein are methods and systems for painting driving assistance markings using one or more paint materials which are visible in a plurality of light spectral ranges, in particular, visible light and one or more infrared light spectral ranges. Further disclosed are methods and systems for analyzing images captured in multiple spectral ranges to identify the driving assistance markings and/or part thereof in a plurality of different spectral ranges and identify aggregated driving assistance markings by aggregating the driving assistance markings identified in the plurality of different spectral ranges. Also disclosed herein are methods and systems for presenting and detecting enhanced driving assistance markings on one or more elements under one or more paint materials which are highly transparent in one or more infrared spectral ranges while reflecting visible light conforming to a color of the element(s) surface thus not affecting appearance of the element(s) in the visible light spectrum.

Starting from a set of plans, such as, without limitation, blueprints, drawings, or Autocad® files, a system and method for calibrating such plans and transferring such plans into a computer readable file and loading a specially designed electronic version of such plans into a hardware-based system that locates, adjusts, transfers, and prints, to a desired scale, a lasting image of said construction plans drawn onto a building surface.

Systems and method for applying roadway marking materials into a groove(s) in a roadway surface and/or forming a recessed groove(s) in a roadway surface. The systems and methods incorporate a contour sensor that provides real-time information of the marking material and/or groove. Based on the contour information, a marking material applicator can be aligned with a recessed groove in a roadway surface to ensure the marking material is applied within the confines of the groove. Alternatively, such contour information may be acquired during groove formation to ensure depth, tilt and/or bottom surface smoothness of the groove is within predetermined limits.

Trafficked pavement substrates utilize markings to segregate traffic (e.g., divide lanes traveling in the same direction, divide sides of the road traveling in opposite directions). A dry polymer modified cement mixture may be used to provide the markings. The dry polymer modified cement mixture is prepared by mixing a dry polymer modified cement blend (ordinary Portland cement, aggregate and polymer powders) with water. The location of the lines is identified, and the dry polymer modified cement mixture is applied onto the identified areas as a thin layer. The dry polymer modified cement blend may include polymers to provide colored markings. Glass beads may be embedded into the dry polymer modified mixture before it cures to retroreflect light shined thereon. The trafficked pavement substrate may have troughs formed therein and the dry polymer modified cement markings may be formed therewithin so that the markings are flush.

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.

The present disclosure involves processes for assessing and modifying pavement surfaces using a mobile platform. An emitter associated with the mobile platform generates electromagnetic waves directed towards a portion of a pavement surface. A condition sensor associated with the mobile platform receives electromagnetic radiation from a first portion of the pavement surface and generates a first electronic signal representative of a current condition of the portion of the pavement surface. A location sensor generates a second electronic signal containing location data corresponding to the first portion of the pavement surface. A computing platform is used to process the electronic signals and create a current pavement condition data point. The computing platform may compare the first electronic signal against a reference representative of a target condition of the portion of the pavement surface, determine if there is a condition variance, and determine whether any condition variance exceeds a predetermined threshold. If a condition variance exceeds a predetermined threshold, the computing platform may generate a condition control signal which is transmitted to a pavement surface modification system, and which operates to modify operation of the pavement surface modification system in order to reduce the condition variance.
