Town Seeks Contractor for Adaptive Traffic Signal Management Project

September 7, 2022

Aiming to help traffic flow better through its signalized intersections, the Town of Hilton Head Island is seeking a qualified contractor to design and implement an Adaptive Traffic Signal Management (ATSM) system.

ATSM uses technology to change and adapt the timing of traffic signals based on actual traffic demand.

"We operate and maintain traffic signals at 25 intersections along William Hilton Parkway, Palmetto Bay Road, and Pope Avenue. When combined, more than 2.5 million vehicles on average pass through those intersections every day," said Shawn Colin, Assistant Town Manager - Community Development.

"As part of our strategic initiatives to enhance the traffic experience for our residents and visitors, we are looking for a system that will help ease congestion, minimize stops and delays, and allow traffic to flow more efficiently through the intersections," Colin said. "With adaptive traffic signal management, we will improve traffic flow by optimizing the timing of traffic signals in real time based on current demand. This will be beneficial with the volume of traffic on William Hilton Parkway and other roads."

On September 1, the Town released a request for proposals (RFP) from contractors specializing in an ATSM system that can accomplish the following:

• Reduce congestion, travel times, intersection delays, and number of stops on the arterials (main roads).
• Reduce emissions and fuel consumption by reducing vehicle stop and idle times.
• Improve corridor safety by reducing arterial stops.
• Provide accurate and reliable vehicle and passive pedestrian and bicycle detection systems.
• Adapt traffic signal timing and cycles in real time for incidents such as special events, traffic crashes, construction, weather, or other anomalies.
• Enhance the communications and coordination between the Town and other local public agencies to create a region-wide approach to traffic management.

The system should also be able to accommodate additional traffic signals that may be needed in the future and provide continuous real time monitoring of all intersections.

Proposals must be submitted by 5 pm, Monday, October 10, 2022. The Town has allocated $2 million for traffic signal project and hopes to launch it by the end of this year.
