Ohio DOT Vehicle Detection Devices

Status

Existing

Descripton

Represents roadside devices installed for the purpose of measuring vehicle speed, volume, and occupancy or density. This data can then be used for both the calculation of travel times and incident identification. The conventional form of vehicle detection is side-fired radar detector (SFRD). The main use of SFRD is for ramp metering, where the detectors provide traffic data to both the local ramp meter and central software, and allow for dynamic ramp metering along corridors and localized traffic-responsive ramp metering at spot locations. Vehicle detection devices gather traffic counts along Ohio DOT roadways and report data to the Traffic Data Archive System. The majority of devices exist within major cities, though more are planned for installation throughout the state.
