PDP stands out for its knowledge of the roadside equipment, hardware, software, and systems integration needed to provide a smooth-running SWZ system. We are a systems company and pride ourselves on high-quality customer service and training – we will never just ship out equipment and leave you struggling to make it work. As integrators, we understand every aspect of our business and can integrate the Smart Work Zone System with your existing ITS equipment.
Smart Work Zones are not a side business for PDP. We are the smart work zone experts, meaning we can provide you with a high-quality, dependable system at a competitive price. PDP provides portable ITS products and is experienced at integrating with existing fixed ITS, as well as other systems and providers.
PDP Smart Work Zone Systems is a member of ITS America (Intelligent Transportation Society of America), ATSSA (America Traffic Safety Services Association) and attends NCUTCD.
PDP was founded in 1996 as PDP Associates Inc. by Dr. Prahlad D. Pant. Dr. Pant performed the initial R&D on Smart Work Zone Systems while a professor of Civil Engineering at the University of Cincinnati. In 1995, he published and presented the first ever paper on Smart Work Zone Systems at IEEE, the world’s largest professional organization for technology. His team at PDP have continued since developing high-quality smart work zone systems incorporating cutting edge technology.
Independent Transportation Research Board (TRB) studies and a variety of other studies have confirmed the effectiveness of PDP’s systems:Horowitz, Weisser, Notbohm: Diversion from a Rural Work Zone Owing to a Traffic Responsive Variable Message Signage System, 2003, Transportation Research Board
Zwahlen and Russ: Evalutation of the Accuracy of a Real-Time Travel Prediction System in a Freeway Construction Work Zone, 2001, Transportation Research Board.
PDP has installed smart work zone systems in NH, CT, MD, NJ, OH, KY, WI, MI, MA, MO, OK, AR, NC, SC, LA, GA, FL, CO, and TX. Some of these systems have generated awards for the Departments of Transportation that have installed them, such as the one awarded in 2011 to Connecticut DOT below for a system provided by PDP.
In 2018 PDP Associates was reorganized and transferred to Will Sisk and renamed PDP Smart Work Zone Systems. Will Sisk has been the leading designer behind PDP for years and is proud to take the helm and continue the outstanding performance of the company going forward.
