Adaptive Traffic Signal Management System

A new adaptive traffic signal management (ATSM) system the Town installed uses advanced technology to improve travel times and the flow of traffic along William Hilton Parkway. With the new traffic signal management system, motorists and pedestrians benefit from major improvements to operations and safety, as well as air quality through reduced vehicle emissions.

A key benefit of the ATSM system is its ability to adapt operations in real time, a function that traditional signal systems do not have. ATSM uses technology to change and adapt the timing of traffic signals based on actual traffic demand and variations in demand.

The upgraded, adaptive signal system will:

  • Monitor the location of pedestrians and bicyclists within the immediate vicinity of traffic signals to minimize delays for motorists when the bicyclists and pedestrians have finished crossing the street.
  • Adapt signal changes as warranted to allow pedestrians or bicyclists that are still in the crosswalk to complete their crossing before motorists are given the green traffic signal to drive through the crosswalk.
  • Feature video cameras to provide enhanced detection. These cameras will not record any footage nor be used for any law enforcement purpose. However, the video camera technology will make it possible to locate and monitor the movement of all pedestrians and bicyclists in the vicinity of the traffic signal.

Pedestrian signals at strategic locations will be motion-activated and provide audible spoken-word messages to better serve pedestrians with disabilities.

Installation of the adaptive traffic signal management system on Hilton Head Island is an initial step towards advancing work on a regional integrated system.
