New signals at 46 intersections that adapt to the flow of traffic could reduce congestion significantly in steadily growing Lexington, a study Monday says.
The proposal sets the stage for town leaders to decide if modern technology is a quicker and cheaper way to lessen bottlenecks instead of $80 million in new roads.
It certainly has the potential to be our long-term solution, Mayor Randy Halfacre said.
Mile-long backups are common on U.S. 1, U.S. 378 and S.C. 6 commuter routes that weave in and out of the community during rush hours.
The new signals would be concentrated downtown where the three roads intersect. About 81,000 vehicles converge there daily, state traffic counts say.
Other signals are needed on Old Cherokee Road on the north edge of town and Wise Ferry Road to the west for better traffic flow from neighborhoods in those areas, the study says. About half of the intersections earmarked for the new signals are in town and the other half surround it.
Halfacre wants to work with state transportation and Lexington County officials to put the network in place so congestion isnt shifted from inside to the outskirts of town.
No price for the network of what are known as adaptive signals is known yet. Building it is estimated at nearly $5 million, but other costs like designing it are undetermined, the study said.
