SynchroGreen® is a real-time Adaptive Signal Control Technology (ASCT) solution from Trafficware. SynchroGreen collects traffic data at signalized intersections, analyzes the data for changing trends, and adjusts traffic signal timings in real time based on the current demand. SynchroGreen is a revolutionary software-based ASCT that can be implemented in many existing traffic controllers. This product uses standard (non-proprietary) vehicle detection technology and provides and intuitive interface and platform to implement ASCT.

Adaptive Signal Control Technology
Simply put, an ASCT adjusts signal timing plans in real time “based on the current traffic conditions, demand, and system capacity” (1). ASCT is an emerging technology quickly gaining momentum in the United States. While early ASCT systems date back to the 1970s and early 1980s, prior generations of ASCT have mainly been used for research purposes, and have not been designed or developed for large-scale deployment (1). In addition to improvements in ASCT algorithms and logic, the newest generation of ASCT benefits from modern traffic controller design, micro-processing, advancements in vehicle detection, and high-speed communications to provide more reliable adaptive operations for rapid large-scale deployment. The Federal Highway Administration (FHWA) states that ASCT is “proven and market ready” and furthermore recommends that agencies explore this technology to improve safety and reduce congestion.
[In 2010, congestion in the United States cost $101 billion as a result of delay and extra fuel consumption.]
Implementing ASCT maximizes the capacity of an existing traffic system. ASCT is most effectively applied where dynamic traffic patterns occur, and actuated-coordinated timing plans cannot reasonably accommodate fluctuating traffic conditions. Primary advantages of ASCT include: improved travel time, reduced delay, fewer emissions, and fuel savings. In addition, an agency benefits through prolonged effectiveness of signal timing and reduced maintenance of traffic signal timing plans. The result is a substantial improvement that far outweighs the cost of the ASCT implementation. Despite these substantial benefits, ASCT deployments account for less than one percent of the existing traffic signal systems in the United States. In 2010, congestion in the United States cost $101 billion as a result of delay and extra fuel consumption. With such high cost due to congestion, ASCT is a promising alternative to improve traffic operations, given the high benefit to cost ration and relatively low market saturation.
