a multi-disciplined engineering, planning, and consulting firm specializing in transportation, traffic, and
transit.
His lifelong fascination with traffic and passion for solving the regions transportation issues led him
through a career of managing and developing various transportation engineering projects. David
previously worked for several years as a consulting engineer leading various civil, transportation,
traffic, and highway engineering design projects. Prior to consulting, Liebgold was the lead
construction estimator and project engineer at Tilcon New York-New Jersey, focusing on
improvements to their overall construction bidding and estimation processes.
Liebgold is a graduate of the University of California at Berkeley School of Engineering and the
Haas School of Business, where he earned a masters degree in transportation engineering and
a certification in management of technology. He attended Rutgers University College of
Engineering for his undergraduate education, where he received a Bachelors of Science in civil
engineering with honors. He is affiliated with the New Jersey Board of Professional Engineers,
New Jersey Board of Professional Planners, the Institute of Transportation Engineers, American

Practical Considerations for an ACS-Lite Pilot Implementation in New Jersey –
Douglas Dillon / Kathleen Swindler
Douglas Dillon has 11 years experience in Traffic Control Signal Engineering and 15 years of
knowledge in traffic control signal operation and controller programming. Mr. Dillon was
Contract Project Manager for 9 Traffic Signal Optimization Contracts utilizing consultants to
perform traffic studies for multiple traffic signal corridors. Mr. Dillon’s 3 newest contracts include
Traffic Signal Adaptive System Development. This investigates possible installation in the
northern, central, and southern New Jersey regions with various adaptive software packages.
Kathleen Swindler has 10 years of planning and design experience in Intelligent Transportation
Systems (ITS), traffic signal systems, and communications networks. Ms. Swindler is currently
the Project Manager for the Traffic Signal Adaptive System Development portion of the New
Jersey Department of Transportation’s (NJDOT’s) northern region Traffic Signal Optimization
Contract which focuses on preparing NJDOT for a pilot installation of the Federal Highway
Administration’s Adaptive Control Software Lite (ACS-Lite). As part of the process, Ms.
Swindler and Mr. Dillon recently visited the ACS-Lite system in Anne Arundel County,
Maryland.
