Nighttime traffic fatality rates are three times higher than their daytime equivalents. While fatigue and alcohol play important roles in nighttime crashes, Texas [...]
The worst of driving conditions calls for the best of roadway markers. And with their reflective properties, retroreflective raised pavement markers (RRPMs) have guided many nervous drivers safely to their destination on rainy nights. That’s why RRPMs‘ durability and performance are of critical importance to the Texas Department of Transportation (TxDOT). A few years ago, [...]
