Abstract: The objective of this paper is to present an improved paint pavement-marking retroreflectivity degradation model. Previous degradation-modeling methods were reviewed and studied. The paint-marking retroreflectivity data ...

Abstract: This research evaluated the traffic performance of two new service interchange designs—the synchronized design which is related to a superstreet intersection and the Milwaukee B design that is related to a parclo B design—as ...

Abstract: This paper addresses the impact of bead density on paint pavement marking retroreflectivity. The writers collected retroreflectivity data and glass bead images on 40 segments of two-lane highways. Bead density is defined ...

Abstract: This paper introduced a new intersection design, the double contraflow intersection (DCI), that could help at big, busy suburban sites, and explored how well it would work. The DCI uses contraflow left turn lanes on each ...

Abstract: Mobile mapping systems (MMSs) are based on advanced technologies for automatically collecting roadway inventory data. A host of advanced technologies, such as the Global Positioning System for collecting georeferencing ...

Abstract: Minimum retroreflectivity standards issued by the Federal Highway Administration (FHWA) have focused the attention of highway administrators on improving the nighttime performance of signs. This paper outlines the development ...

Abstract: The objective of this research was to determine the performance characteristics of thermoplastic pavement markings in North Carolina and to create viable degradation models. Additionally, an evaluation of paint pavement-marking ...

Abstract: Traffic signal warrants documented in the
