Thousands of traffic lights could be switched off at night under radical plans being drawn up by the Conservatives. Others could be stripped out completely in an attempt to cut delays and reduce carbon emissions by improving traffic flow. It is estimated that there are around 140,000 sets of traffic and pedestrian signals in Britain, with the number having increased in recent years. In London, for example, the number rose by 42 per cent over the past decade and there has been growing public anger about their proliferation across the country. At the same time the removal of some lights for example in Scarborough and Portishead in Somerset, has led to improved traffic flow without any increase in casualties. “There is a very real suspicion that thousands of traffic lights across the country are creating rather than cutting congestion,” Mrs Villiers told the Daily Telegraph. “It is time for a radical change in this country’s approach to traffic signals. I am certain that there are many sets of signals that could be removed or turned off at night without jeopardising pedestrian safety.” An array of options are being considered, including switching some lights to flashing amber at night, which means motorists should proceed with caution. Although this is commonplace on the continent, a change in the law would be needed for this to be brought into practice in Britain. The Tories are also backing plans to allow cyclists to turn left at red lights. This, the party believes, would reduce the risks faced by those on a bike. More
