Ramp signals, are quick change traffic lights on motorway entry ramps to manage the flow of vehicles entering the motorway. When the red lights appear, drivers stop and wait for the green signal. When lights turn green, one vehicle per lane will be able to drive along the ramp and merge onto the motorway.
The ramp signals only operate during busy periods to improve traffic flow; they stay off at other times. Sensors in the road detect when traffic becomes heavy, and the system turns on the ramp signals to regulate the total traffic flow entering the motorway. This prevents congestion and flow breakdown on the highly trafficked motorway and better manages the conflict between vehicles merging and motorway traffic.
Ramp signals run on a fast cycle, with only a few seconds between green lights, as compared to standard traffic lights which can take up to one to three minutes.
Speed and lane use signs are used to deliver real time information to drivers by allocating and managing lane use across the motorway. Speed limits can be changed in response to traffic conditions to improve road safety, traffic flow and provide a consistent journey. Speed limits may change in response to busy periods, incidents, roadworks or weather conditions such as high winds or flooding.
The speed and lane use signs also display arrows and crosses to direct traffic around incidents or hazards that may be on the motorway.

By controlling the timing of vehicles entering the motorway, ramp meters enable safer merging while maintaining a smooth flow of traffic on the motorway. They help people travelling on the motorway to enjoy more consistent speeds and predictable travel times with less congestion. It also means less stop-start traffic and less sudden braking, meaning less wear and tear on vehicles and a reduction in the risk of crashes.
Variable message signs (VMS) will be located at key decision making points along your journey to provide real-time information about traffic conditions and expected travel times. This will help you to make decisions about which route to take before entering the motorway and once on the motorway.
We will be carrying out a community roadshow where you can learn about Smart Motorways and ask questions about the project. Please feel free to drop in at the following locations:
