• Abstract:
  The FHWA’s Every Day Counts (EDC) initiative identifies adaptive signal control as a tool for local agencies to deploy
  
  innovation. In an effort to achieve the goals of the EDC initiative, the traffic sections of the Colorado Department of
  
  Transportation (CDOT), in Region 2 and 4 and the City of Greeley implemented adaptive traffic signal control systems on
  
  10th Street (US 34 Business) in Greeley and US 24 in Woodland Park. This new technology uses real-time data collected
  
  by system detectors to optimize signal timing for each intersection in the corridor. The use of real-time data means that
  
  signal timing along the corridor changes to accommodate the traffic patterns at any given time of the day.
  
  There are many different adaptive traffic signal control systems of which two, InSync and QuicTrac, were selected for
  
  implementation in Colorado. The InSync adaptive signal control system, produced and supplied by Rhythm Engineering,
  
  was installed in Greeley on 10th Street and the QuicTrac adaptive signal control system, produced and supplied by McCain,
  
  Inc., was installed on US 24 in Woodland Park. The evaluation of the performance of these systems on their distinct
  
  corridors was documented in separate reports and provided to the agencies and stakeholders. This report focuses on a more
  
  direct comparison between the two systems including costs for installation, maintenance, and expected benefits on a per
  
  intersection basis. The study is not intended to recommend a preferred system, but present the results for each system and
  
  provide data allowing decision makers to make an informed decision when selecting an adaptive system.
  
  Implementation
  
  Proper application of adaptive signal control can reduce congestion, smooth flows, improve travel times, maximize the
  
  benefits of signal timing, and potentially reduce crashes.
