Ohio DOT Ramp Meters
Ramp meters are traffic signals at freeway entrance ramps, which use video detection cameras positioned on the ramp and freeway to determine how quickly drivers can safely enter the freeway. Ramp meters also coordinate timings based on input from Ohio DOT Vehicle Detection Devices that measure traffic speed and volume on the freeway, and traffic demand on the ramp.
