Ramp control signs are activated from the VicRoads Traffic Management Centre and may be directly linked to adjacent traffic signal control equipment controlling the traffic signals at the on-ramp where such exist, or connected to the SMR network.
Ramp Metering Signs form part of a Ramp Metering System and are activated from the Ramp Metering Controller. A typical Ramp Metering System consists of a Ramp Metering controller, 3 aspect traffic signal displays and Ramp metering signs. During operating times, the Ramp Metering System allows one car at a time, per lane, to enter the freeway.
