Speed bumps should be removed from the road as part of the width
The health watchdog has put forward a series of proposals to reduce air pollution by thousands of people every year.
In a report on how to make the air cleaner, the National Institute of Health and Care Excellence (Nice)
He said that measures to help drivers maintain constant speed rather than acceleration and deceleration are better than humps.
Earlier this year, a study by Imperial College of Technology found that forcing drivers to slow down and accelerate can again produce a lot of harmful emissions.
Other plans proposed by Nice include the separation of cyclists and cars with leaves;
Move the living room to the back of the house, away from busy roads, and prohibit "parking" outside schools and nursing homes ".
The draft guidelines published today said that planners must take into account the impact of air pollution when designing a speed reduction program, and any "physical measures" must be designed to minimize the consequences of sharp deceleration and acceleration.
They believe that showing signs of speed can serve as an alternative to speed bumps, can use the average speed camera more, and can also set variable speed limits on busy roads.
Ralph Bagh, South Bucks District Council leader and vice chairman of the nice steering committee, added: "smooth driving reduces emissions and stops --
It is harmful to start the acceleration and deceleration brake.
It sends out more through its tail.
But second, braking is also very fine particles that grind into the atmosphere.
"With a 20-mile/hour limit, proper humps and bumps are not the most effective way to do this, because most people tend to speed up to about 30 mph and step on the brakes, travel 15 miles/hour on the hump and then accelerate again.
"So this is a very ineffective deterrent in terms of emissions.
We would say we want them to be a better way than that.
"Imperial research found that on a street in north London with a speed limit of 20 miles/hour and a road hump, a gasoline-driven car generated an increase in carbon dioxide by 64% (NO2)
More than on a 20-mile/hour street with road mats.
It also produces more than 47% of particulate matter (PM)
And more carbon monoxide (CO2)emissions.
RAC road policy spokesman Nick Lyes said that rethinking the speed bump is worthy of "serious consideration" and "it is recommended that local authorities consider again the speed bump that causes the driver to brake and then accelerate again, this is a great potential to improve local air quality.
"Nice also recognizes the importance of improving traffic flow-because air quality is often the worst place to have congestion, which RAC has raised on many occasions.
"Air pollution kills 25,000 people in the UK every year, causing heart disease and worsening respiratory disease.
But the UK's road usage reached a record level, with an estimated 320 billion miles of vehicles in the year to September 2016, leading to air pollution in about a third city.
Nice also called "No.
Idling around schools across the country "area to prevent parents from leaving their cars during school operations.
Road planners should avoid cycling on heavily polluted routes and, where it is inevitable, consider installing leaves to screen cyclists.
Cities and towns with pollution problems should consider implementing clean air zones and study the possibility of introducing congestion charging zones, they recommend sa, and considering health supervision agencies such as "No Car Day" also encourage home builders to put the living room behind a house away from the road, and planners should ensure that new schools are built, nurseries and nursing homes are built away from busy roads.
The guidelines will be open for comment by next summer, but the government is under pressure to fundamentally improve air pollution, or faces huge fines for missing European clean air targets.
Professor Paul Lincoln, CEO of the UK Health Forum and chairman of the NICE guidelines committee, said: "Given the need to meet EU and national air quality standards, the guidelines are very timely.
"I hope that when finalized, this guidance will prove to have an impact on reducing the air pollution that we are exposed to every day.
However, some experts said the report did not do enough to deal with major polluters such as diesel cars.
Professor Jonathan Grieger, professor of pediatric respiratory and environmental medicine at Queen Mary College, University of London, said: Although the report clearly states the emissions of diesel cars, it gives the impression that targeting diesel is not particularly effective.
"Without an effective national diesel policy, such as a scrapping plan, local initiatives may either not be able to be implemented or at best can only make minor changes to exposure with limited health benefits.
Jenny Bates, a friend of the Earth's air pollution activist, said: "Action is needed to ensure that the vehicles on the road are clean, and less action is needed.
The most polluted diesel vehicles must be phased out, and our transportation and planning policies need to be thoroughly reformed.
But the British Lung Foundation (BLF)
British Heart Foundation (BHF)
He said the proposed measures were a welcome step in the right direction.
"Air pollution causes thousands of premature deaths every year.
It increases the risk of lung cancer and harms lung development in children, "said Dr. Penny Woods, BLF's chief executive.
"Given the seriousness of the problem, we welcome this draft guide and look forward to seeing the final plan.
