<p>Work zone safety traffic control is an area that has been gaining a lot of attention during the past few years. Travelers come across several types of work zones on a regular basis due to increased maintenance and reconstruction along the nation?s highways. Work zones pose a hazard to the regular traveler in terms of safety. Evidence suggests an increasing number of fatalities, injuries, and costs due to work zone-related accidents. According to the National Work Zone Safety Information Clearinghouse1, in one year, work zones are associated with more than 700 fatalities, 24,000 injury crashes, and 52,000 property damage-only crashes and the estimated cost of these crashes exceed $ 4 billion per year.
