SWARCO McCain, Inc. provides the first Adaptive Signal System and Low-Voltage ATC Cabinets in Connecticut improving safety, lowering costs, and reducing travel time
SAN DIEGO, California, February 28, 2023 - SWARCO McCain, Inc., a long-standing industry leader in Intelligent Transportation Systems (ITS), has supplied the Town of Greenwich, CT with a state-of-the-art Adaptive Signal System and low-voltage ATC cabinets. This is Connecticut’s first traffic signal system of its kind, aiming to decrease travel time and congestion and improve air quality and traffic flow.
“Adaptive Signal Control Technology (ASCT) makes traffic signals more effective and efficient. Unlike traditionally timed traffic signals, ASCT accommodates changing traffic patterns caused by traffic crashes, special events, road construction, and other roadway incidents by calculating a traffic signal timing plan in real-time,” said Gabriella M. Circosta Cohee, P.E., Town of Greenwich Senior Civil Engineer and Project Manager. “The new adaptive traffic signal system can detect an influx of vehicles and can improve the traffic congestion by instantly adjusting the timing of the traffic lights at all five intersections.”
On Arch Street, all five intersections received a 352i Low Voltage DC ATC Cabinet. These cabinets contain the latest technology needed to run the signalized intersection. The major components of the cabinet include the Cabinet Malfunction Unit (CMU), Traffic Controller (CU), and Video Detection Processors. The SWARCO McCain, Inc. Adaptive Signals were part of a wider project that received $2.75 million in funding through the Federal Highway Administration’s Congestion Mitigation and Air Quality (CMAQ) program.
The video detection processors were installed at all five intersections along Arch Street, which is traveled on by approximately 35,000 vehicles daily. The cameras collect data on queue length, directional traffic flow, and vehicle delays. They can detect motorized vehicles, bicycles and pedestrians. The cameras send signals to the traffic controller so it can respond appropriately. The McCain Transparity® Adaptive Software receives the traffic data from the controllers and the signal timing is adjusted and improved based on the data received. Since this technology is steadily monitoring the roads, traffic flow is consistently modified depending on traffic patterns throughout the day.
McCain Transparity Adaptive software has the ability to effectively analyze real-time traffic conditions, calculate optimal signal timing, and measure performance. It is compatible with all industry standard detection types and uses wireless communication.
The town of Greenwich hopes this new signal system, which uses 66 per cent less energy, will have a significant impact on traffic coming off I-95. The stretch of I-95 leading up to Exit 3 regularly becomes congested, with many cars slowing down to take the exit ramp and turn onto Arch Street as they head into downtown Greenwich.
