One of the major emerging technologies in highway safety has been the improvement of the types of retroreflectivity sheeting used on overhead signs on roadways. Modern signs are very efficient at returning light back to the driver, creating a much safer nighttime driving environment. Because of this, many departments of transportation are opting to remove […]

TTI Researchers Identify Elusive Relationship Between Safety and Pavement Marking Brightness
In what is described as a key breakthrough regarding safer nighttime driving, Texas A&M Transportation Institute (TTI) researchers have identified a technique for developing safety-based retroreflectivity criteria for pavement markings. The technique, described in a Transportation Research Board paper submitted by TTI Senior Research Engineer Paul Carlson and TTI Associate Research Scientist Raul Avelar, quantifies […]
Rural Roadway Signage: When Brighter Is Not Always Better
Ever since agencies started using uniform traffic signs, the conventional thinking concerning nighttime visibility is that brighter is better. But a recent Texas A&M Transportation Institute (TTI) research project revealed that signs along rural highways can be so bright that they cause disability glare to the point of reduced hazard detection distances, which can be […]

New Study Shines Light on Pavement Markings and Safety
When you drive at night and your headlights illuminate a lane marking, it makes you feel safer, right? After all, bright pavement markings are designed to help you stay in your lane and prevent you from running off the roadway. Called retroreflectivity, special materials in edge lines and lane lines create the brightness. With age […]
