In most parts of the United States and many countries around the world, traffic congestion, crashes, and traffic flow are major issues. It seems there are more vehicles every day on the same number of roadways, and construction of new roads or additional lanes on highways isn’t happening fast enough. Where roadway construction is occurring, traffic can be significantly impacted during the project. Couple the increased volume with emerging issues like higher speed limits and distracted drivers and the need to effectively manage traffic flow, particularly during an incident, is even more important.
