Analysis of Factors Affecting Pavement Markings and Pavement Marking Retroreflectivity in Tennessee Highways
… visibility is quantified into a parameter called retroreflectivity, which is a measure of how well the markings can be seen by road users. The importance of the factors affecting pavement markings differs from one publication to another, which cause the effective management of pavement markings a …

Optimization of Pavement Marking Performance
… region. The markings were evaluating using retroreflectivity and visual rating. From the collected data, degradation models were created using exponential models presented in the literature. The degradation models were implemented by using practical methods for assessing pavement marking …

Leaching of metals and metalloids from highway marking glass beads and the potential environmental impact
… 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 research …

Assessment of the Effectiveness of Emergency Lighting, Retroreflective Markings, and Paint Color on Policing and Law Enforcement Safety
… the police vehicle. Similarly, the addition of retroreflectivity to the rear of the vehicle showed an additional benefit for causing drivers to move over sooner. However, these benefits came at a cost to the officer's visibility. When outside of their vehicle, the high output blue system …
