Highway agencies seeking a more viable way to check the quality of asphalt construction than through sample cores are considering dielectric profiling systems (DPS) as a solution. DPS use a ground-penetrating radar (GPR) to collect dielectric values from the underlying surface that help measure air voids or nonuniformity of newly laid hot-mix aspha

High friction surface treatment (HFST) is a safety-first pavement treatment intended to restore and maintain pavement friction to reduce crashes. The cost of HFST is high compared to typical maintenance treatments; however, HFST is highly effective at reducing wet-weather and run-off road crashes. Improvement in the state of the practice can promot

President Harry S. Truman was an avid motorist his whole life. As President (April 1945-January 1953), he remained concerned about the growing traffic safety problem – and with good reason. Fatalities had reached 38,142 in 1941. Any number would be too high, but President Truman took a moment in time, as traffic volumes were returning to peacetime

The Ohio Department of Transportation created the Pedestrian Safety Improvement Program to rapidly implement low and medium-cost countermeasures along arterials and collectors. The program incorporates STEP countermeasures at midblock locations and intersections.
The Los Angeles Department of Transportation (LADOT) installed a road diet on Rowena Avenue in the Los Angeles neighborhood of Silver Lake in 2013. The four-to-three lane conversion along the high-volume corridor resulted in fewer overall crashes and increased bicycle usage. Since the Rowena Avenue project, LADOT has implemented dozens of road reco
