If there's one concern many Port Orange residents have, it's the traffic on Dunlawton Avenue.
But wait times could improve with the installation of adaptive signal control technology that would be able to adjust the timing of red, yellow and green lights to aid changing traffic patterns with a goal to reduce congestion.
Construction on the adaptive traffic signal system is slated for 2020 and would run along Dunlawton Avenue from Summer Trees Road to A1A. Currently, the installation is set to cost $949,500, though that is subject to change, depending on the system that is selected.
Sara Shepherd, FDOT Consultant for District 5, wrote in an email that adaptive signal control technology can continuously distribute green light time for all traffic movements while progressively moving vehicles through green lights.
When the signals adapt to real-time traffic conditions, congestion and crashes are reduced, according to Lois Bollenback, executive director with the River to Sea Transportation Planning Organization.
Bollenback said that the current signals require a technician to set the timing to respond to traffic conditions. Adaptive signals would be able to change when traffic patterns change.
"Environmental benefits, including reduced fuel consumption and decreased vehicle emissions, are also realized as a result of reduced congestion," she said.
In Volusia County, adaptive signal control technology is currently used on parts of U.S. 17/92 in DeLand and parts of U.S. 92 in Daytona Beach.
The River to Sea TPO is also in the process of developing a master plan for Volusia and eastern Flagler counties.
"Local concerns include traffic congestion, excessive delay at intersections and lack of progression along the corridor," Bollenback said, adding that "rather than building more roads, these projects help us use the existing facilities more effectively."
