Lights on thousands of miles of major roads in England could be dimmed（变暗）
during quiet periods in a bid to save money and reduce carbon emissions from various
vehicles.
The Highways Agency suggests reducing light levels on A-roads when traffic levels
Are“ very low". I:ocal transport minister Norman Baker said he supported the．Move on
condition. that safety was not compromised.
Research into when and where lights could be dimmed will begin in May，2012.
Mr．Kawczynski, a MP（国会议员），asked Transport Minister Norman Baker
“what plans he has to change guidance on the,minimum amount of lighting required on A
roads". In reply，Mr. Baker wrote：“The Highways Agency has plans to reduce the
level of lighting on A-roads when traffic levels are far below road capacity. The agency
has no plans to reduce the level of lighting on A-roads during the peak（高峰）periods
that occur during the hours of darkness or to temporarily switch A-roads lighting off
when traffic flows are low. “The level of light．reduction will be based upon
internationally agreed standards and made after discussion and_agreement with the UK’s
Institution of Lighting Professionals.”
Mr. Baker added：“It is right that lighting authorities consider，in the interests of
cost-saving and the environment，whether lighting can be sensibly dimmed or turned off .
with proper safety brought into full consideration.”
A Highways Agency spokesman said："This is not about switching off lights on A-
roads. Any changes to light level will be determined after discussion and agreement
with industry experts and will meet internationally agreed standards to ensure there will
be no influence on safety for road users.”
