The traffic on the roads of great Britain is now at a level similar to that observed in the late 1980s and early 1990s, the AA said.
He rolled between 35% and 40% of the pre-coronavirus volume at the beginning of the lockout, but has since doubled to reach about 75%.
AA head of roads policy Jack Cousens told the BBC that the traffic could return to normal ” by the end of the month of July “.
But the Friends of the Earth believes that the pollution should not be allowed to “creep” back in the pre-pandemic level.
The traffic has gradually increased since the beginning of April, that the travel restrictions have eased and hundreds of thousands of people have returned to work.
The government is trying to deter people from using public transport if it is avoidable, and said the passengers to wear masks, in an effort to limit the spread of the coronavirus.
Mr Cousens said: “The message to avoid the public transport is certainly resound as, week by week, more people have ventured into their cars. ”
He added that “because of the disappearance of the night-time economy” and there was ” very little traffic after 19:00, while the weekends were quieter than usual due to the cancellation of mass events.
“As the shops re-open, while the stylists and the other near the professions to prepare to return to the beginning of July, the traffic could reach the level of lock by the end of July,” Mr. Cousens said.
UK carbon emissions have fallen by 31% in April, but have since increased.
Mike Childs, head of science at Friends of the Earth, said: “Any decrease in emissions during the forced lock will be for nothing if the levels ramp back in place.
“In saying that people should take the wheel now, the government themselves contribute to the pollution increase of the use of the road. ”
The UK government has pledged £250 for improvements in cycling and walking infrastructure and many towns and cities the road space available for pedestrians and those on bicycles.
