Drivers catch green lights 'wave'
Local councils can adopt "green wave" systems of sensors, where vehicles at or just below the speed limit trigger a succession of green lights.Environmental and motoring groups say carbon emissions will be reduced.
Previously the Department for Transport (DfT) had discouraged the systems which reduce fuel use, resulting in less tax being paid to the Treasury.
But now, rather than seeing green wave systems as a "cost" to the public purse, the DfT views them as a "benefit".
'Easy target'
The RAC's motoring strategist Adrian Tink said: "Green waves is a common sense win-win initiative that will actually help motorists as they go about their daily lives as well as reduce carbon emissions.
"It's used very successfully in other countries and it would be great to see motorists up and down the UK benefit from its widespread introduction. ...
"But they don't tackle congestion in the long term because they don't give people alternatives to driving."
A DfT spokesperson said: "Tackling climate change is one of the single most important issues we face, and cutting road transport CO2 emissions will play an important part in that.
"Urban traffic control systems, like green wave, help tackle congestion and vehicle emissions in urban areas, and a number are already being progressed as local major schemes.
