Analysis of Factors Affecting Pavement Markings and Pavement Marking Retroreflectivity in Tennessee Highways
Pavement markings are lines drawn on a pavement surface to provide vital information to road users pertaining to lane restrictions and vehicle movements, which if adhered to, results in improved safety and smooth travelling to road users. Pavement markings’ visibility is quantified into a parameter …

A GIS-based traffic infrastructure management system for pavement markers and markings
… diverse and distributed throughout the region. Pavement markings and marker materials are used to delineate travel lanes on roads and at intersections, and they are a key component of the roadway system. They play a vital role in facilitating safe traffic operations on roadways. The management …

Optimization of Pavement Marking Performance
<p>Pavement markings must perform on a variety of asphalt and concrete surfaces. Surface preparation can also affect a markings initial visibility and long-term performance. Therefore, there is a need for information on the performance of pavement markings under many conditions including type of …

Leaching of metals and metalloids from highway marking glass beads and the potential environmental impact
Glass beads are embedded in pavement markings to obtain retroreflectivity which plays a crucial role in the lighting-up effect needed for safe driving. Elevated metal and metalloid concentrations of As, Sb, and Pb have recently been observed in imported glass beads. The main objective of this …

Image-based recognition, 3D localization, and retro-reflectivity evaluation of high-quantity low-cost roadway assets for enhanced condition assessment
… assets such as traffic signs, guardrails, and pavement markings requires frequent reporting on location and up-to-date status of these assets. Today, most Departments of Transportation (DOTs) in the US collect data using camera-mounted vehicles to filter, annotate, organize, and present the …
