## Ramp Meter Traffic Signals: 

A ramp meter signal is used to control traffic entering a freeway from an interchange entrance ramp. 

When a ramp meter is displaying a circular red display, vehicles facing the red light must stop. When a ramp meter is displaying a circular green display, a vehicle facing the green display may proceed to merge onto the freeway. When the display is dark or not emitting a red or green display, a vehicle may proceed without stopping and enter the freeway by merging or yielding as normal conditions allow.

## Hybrid Beacons 

Hybrid beacons may be used to control traffic at mid-block crosswalks and entrances to emergency response facilities. The beacons remain dark until activated by pedestrians or emergency response personnel. Once activated, the beacons will flash yellow for a few seconds, then go steady yellow and steady red for a few more seconds to allow moving vehicles to safely stop. Once vehicles have stopped, the beacons will remain steady red while pedestrians begin crossing or the emergency response vehicles begin exiting their facility. After several seconds, the beacons will begin flashing red, during which time vehicles are to remain stopped until the pedestrians or emergency response vehicles have cleared the intersection. After the pedestrians or emergency response vehicles have cleared the intersection, and after first coming to a complete stop, vehicles may begin moving while the beacons are flashing red.
