OREM The Utah Department of Transportation will begin using a ramp meter system on I-15 in Utah County beginning today.
Ramps between Lehi and Orem will have traffic signals that will control vehicles entering I-15. Each lane on the ramp will have its own signal with a green light running long enough to allow one vehicle to enter onto the freeway per lane, alternating between the lanes. There will also be an electronic sign at each ramp entrance notifying drivers when the ramp meter is on.
Initially, the meters will be in operation on northbound ramps from 7 to 8:30 a.m. and from 4:30 to 6 p.m. Meters on southbound ramps will be in operation from 4:30 to 6 p.m. These times and locations are subject to change.
"During the morning and afternoon commute, groups of vehicles attempt to access I-15 at the same time, which slows down traffic," said UDOT project manager John Higgins in a statement. "Ramp meters regulate how frequently vehicles access I-15 by creating gaps, which allow motorists to merge safely without creating additional travel delays."
The ramp meter system is expected to improve safety and the overall operation of the freeway system and reduce overall vehicle emissions.
Ramp systems have also been used on I-15 in Davis County and in Salt Lake County from 600 South to 10600 South.
