The National Institute for Health and Care Excellence (NICE) has produced a new guideline document that suggests variable speed limits could reduce air pollution around motorways.
Professor Mark Baker, director of the centre for guidelines at NICE said: “If the traffic is such that you are stopping and starting, decelerating and accelerating, then that increases emissions, pollution and fuel consumption.
“In those circumstances, slowing everything down to 60mph or 50mph is the best approach – but not all the time. That’s why variable speed limits are far more sensible than blanket 50mph or 60mph (limits).
“Variable speed limits are useful where at times the volume of traffic results in unhealthy driving conditions – which is stopping and starting. So M25 most of the time, M4 on a Sunday, M1 on a Friday evening.
“Variable speed limits are justified on roads which are busy enough for traffic to have to break for no other reason than that (the road is) blocked
“The battle against air pollution has to be one we are all fully committed to.”
