“Green wave” schemes to be introduced

Government proposals to relax the rules relating to traffic flows could see the introduction by many local authorities of the so called “green wave” system for traffic lights.

The system, which works through a series of sensors in the road, would allow traffic travelling at or below the speed limit to trigger a succession of green lights, thus improving traffic flow and reducing motorist frustration at meeting a series of red lights.

Although previously discouraged by the DfT, similar schemes already operate successfully in Amsterdam and Copenhagen where the authorities use them as a means for cutting carbon emissions and traffic noise.

Among supporters of the plans are Boris Johnson, London’s mayor, who believes it will help to reduce bottlenecks in parts of London, and the AA, who have expressed some concerns that it could lead to problems on the side streets that feed into the main roads with some drivers on side roads getting impatient and jumping red lights to join the freer flowing traffic.
