Adaptive Signal Control Technology System

Louis Berger was awarded a 2018 Honor Award for Engineering Excellence by the American Council of Engineering Companies (ACEC) of Maine for its work on the Adaptive Signal Control Technology System project in Warwick, Rhode Island.

Warwick’s notoriously busy Airport Road corridor posed a significant public safety concern for local residents. Louis Berger saw an opportunity to improve traffic and safety by implementing a pilot program for state-of-the-art adaptive signal control (ASC) technology that uses near real-time data to adjust traffic signals so as to safely and expeditiously move traffic through the corridor. Louis Berger brought together stakeholders, including the Rhode Island Airport Corporation (RIAC), Rhode Island Department of Transportation (RIDOT) and Federal Highway Administration (FHWA) to implement this first of its kind transportation project in Rhode Island.

Through a grant sponsored by the FHWA, Louis Berger designed and installed ASC at eight signalized intersections located along the 1.5 mile corridor. The system optimizes signal timing for arterials, side streets and pedestrian crossings through infrared detection coordinated with web-based, near real-time ASC. This improves traffic corridor safety and reduces motorist travel time, delays and stops, thereby decreasing idling, fuel consumption and emissions. Designed, bid and constructed in 20 months, the ASC system has been successfully operating for more than one year.

The ACEC Engineering Excellence Awards celebrate the most outstanding project achievements in the field of engineering around the world. Projects are judged based on originality, innovation, value to the public and the engineering profession, complexity, social and economic considerations, sustainability, and exceeding client needs.
