A system for automated pavement marker placement is disclosed, comprising a gun for applying a melted attachment substance onto a road surface, and a marker placement device for positioning a pavement marker onto the substance. The system includes one or more sensors to measure the speed of the gun and marker placement device, and processors to determine activation times for the gun and marker placement device based on speed and distance parameters. The described system addresses the technical problem of precise marker placement at varying speeds, providing a solution that ensures accurate alignment and adhesion of markers. The system is primarily used in road construction and maintenance, enhancing efficiency and accuracy in marker application. The processors dynamically adjust activation times in response to speed changes, optimizing the process for consistent results.

A system and method in which road markings, such as center-lane, shoulder markings and vertically oriented sign markings, are surface coatings configured to transmit machine-readable data to electronic equipment on self-driving or driving-assisted vehicles. In an embodiment, painted markings create a type of matrix code or barcode that can be read by optical detection systems in a vehicle. The data is used to inform active safety systems about road conditions, obstacles, grades, speed limits, turns, HOV, EV, or autonomous lane options, as well as other data, to safely conduct autonomous and semi-autonomous vehicles. In some embodiments markings are applied with coatings that are readable by electronic components and cameras onboard a vehicle, and may not be visible to humans.

The present disclosure describes a preformed or in some cases a hot applied thermoplastic marking composition comprising a planar top surface portion and a planar bottom surface portion that are coplanar to each other, wherein said bottom surface portion is directly applied to a substrate via application of heat or pressure or both heat and pressure and wherein said top surface portion comprises an intermix that exits throughout said thermoplastic composition and includes large grit size aggregate in the range of about 8 to about 20 mesh or grit size, thereby reducing or eliminating tire tracking while also improving long-term skid resistance.

A supplemental tool for installation that can achieve both high magnetic-marker installation efficiency and high magnetic-marker installation accuracy is provided. A supplemental tool for arranging a magnetic marker in an accommodation hole provided by being drilled in a road surface includes a columnar-shaped retaining member including a retaining surface for the magnetic marker at an end portion in an axial direction and a detaching member combined with the retaining member so as to be able to move to the axial direction as opposed to the retaining member. A combination of the retaining member and the detaching member is such that detaching member can abut on the magnetic marker retained on the retaining surface, and it is configured so that the retaining member can retreat in the axial direction to a side away from the magnetic marker keeping a state in which the detaching member abuts on the magnetic marker.
