There are six key benefits for drivers using the new M4 Smart Motorway.
A more consistent drive
Traffic conditions are monitored in real time and entry ramps signals, known as ramp meters, manage the number of vehicles coming onto the motorway with a quick change traffic light system during peak times. These tools ensure a smoother, uninterrupted driving experience.
Crash rates on Smart Motorways are reduced by up to 30%.
Reduced travel times
Traffic keeps moving so overall journey times are reduced.
Current information about traffic conditions
Drivers will be able to see real time information on message boards to help them make informed decisions about their route before and during their trip on the motorway.
Better incident management
If there is a incident variable message signs will indicate the safest speed and which lanes to are usable. These variable signs help improve access for safety crew and emergency vehicles.
Reduced vehicle emissions
When traffic flow is improved and there is less stop-start driving, vehicles have better fuel consumption and produce fewer emissions.
