Ramp signals

Ramp signals are traffic lights, which have been installed at the end of motorway on-ramps to manage traffic flow onto the motorways during peak periods and other busy times. These signals operate automatically when they are needed to improve traffic conditions on the motorway. 

Ramp signals are widely used internationally and have been shown to improve motorway traffic conditions, resulting in more consistent travel times, safer merging and fewer accidents. 

Electronic sensors built into the road detect when traffic conditions change, allowing the system to automatically activate and adjust each ramp signals timing sequence in response to current motorway traffic conditions.
