    Dear James

    Many thanks for your comments. We know from British Social Attitude Surveys that about 70% of people are in favour of 20mph limits for residential roads and busy streets. At the same time about 10% oppose. So I guess you are one of the 10%!

    Yes, roads really are safer, and if you were to replace all the people using bicycles in Westminster with cars then it really would be far more congested.

    And places which provide streets and roads which can be used by all rather than just those in cars are actually more economically successful than those with 20th century ideas of the car being king and used to displace other forms of transport.

    Hi Vanessa
    Our response is that driving more calmly and eliminating acceleration to 30mph will have a very positive effect on air quality. See our press releases

    Hi Gina

    When you put in wide-area 20mph limits you include many roads where the average speeds are already low. You do this for consistency and because it would be ridiculous to maintain a 30 limit on such roads when “faster” roads had a 20 limit. Reductions tend to be proportional to the previous average, with higher ave speed roads achieving the highest reductions. Hence the inclusion of low speeds roads where you will see minimal or zero reduction tends to dilute the overall average reduction.

    On most 20mph wide-area implementations you get approx 1-2mph overall average reduction in speed. But this is skewed with faster roads achieving up to 6mph reduction. Whilst this is quite different from an isolated and physically calmed scheme, such schemes only reduces speed on that small section of road and endorses 30mph on the rest of the road network. You can see our comparison at

    You are correct in considering that authority-wide 20mph limits are far more about setting a social consensus rather than traffic management. The crude sort of analysis conducted by Manchester City Council makes no allowance for this and is critically flawed. See my blog on this at

    Thanks for your comment Peter. I would suggest that a more appropriate comment would be “Yes obviously increasing speed makes the impact worse, saying speed is a feature in all crashes is like saying the height is a feature in all fall from height incidents.”

    All limits are flouted, but what that same DFT report, which only measured free-flowing roads, noted was that speeds on 20mph limits were 6mph lower than those on 30mph roads for all classes of traffic. Note that the report only included a total of 9 20mph sites across the whole country.

  • 20mph cuts air and noise pollution to prevent blighted lives

    20mph limits massively cut toxic diesel emissions. 40,000 die early pa[1] from outdoor fumes – 23 times more than in crashes[2]. 20mph is equivalent to taking over half the petrol cars off the road. Traffic noise also blights lives. 20mph halves perceived noise compared to 30mph. We can’t see pollution, yet it affects our physical and mental health. Demand 20mph today!

  • Isle of Wight Full Council Vote For 20mph limits

    20mph limits have been voted on at Full Council on the Isle of Wight. The 20mph vote was won on Wednesday 19th October.  80% of Councillors supported 20mph for built up areas. Councillor Julie Jones-Evans’ motion called for 20mph limits for “'residential streets, town and village centres, and where people work and learn.”

    Scottish 20mph Default Moves Closer

    The first Scottish 20mph Conference moved the debate forward on a National 20mph limit.  20mph was clearly popular amongst delegates from many Traffic Authorities with 95% “favouring a national default limit of 20mph”. Conference-goers agreed 20’s Plenty. The Scottish Government can lead on a 20mph default for built up areas as this is the best value for money in raising everyday road safety and liveability.

    20mph As Scotland’s National Limit

    People want 20mph streets.  Fortunately 20mph limits are affordable and do-able. What’s the best method? The Scottish Government can lead with a 20mph default for built up areas.  This is a cost effective win-win all round – eg for the legal process, consultation, signage, engagement, higher compliance and enforcement.

    20's Plenty for Manchester - Progress so far

    In February 2012 Labour-controlled Manchester unanimously passed a 20mph motion (proposed by a Lib Dem). In March 2012  the Council Executive agreed to investigate funding for 20mph on all C and Unclassified roads. Estimated cost £2.8m (Total 20) or £41m (with calming). In May 2013 the Executive agreed £500,000 from public health funds to improve road safety. Three areas were prioritised for Phase 1 covering 16% of the network.

    Area 1 – Gorton (Collision Hotspot, Social Deprivation, High Population Density)

              Area 2 – Miles Platting, Newton Heath, Ancoats and Clayton  (Social Deprivation, high degree of community engagement)

              Area 3 – Hulme, Moss Side and Fallowfield (Maximise benefits of the complementary Bus Priority Scheme on the Oxford Road Corridor)

    In February 2014 Traffic Regulation Orders published. Strap line 20 is Enough logo with smiley face featured on banners from school railings. Roadpeace, Key 103 Radio and student volunteers engaged - with access to £200 grants.

    In March 2014 councillors, police, schoolchildren and campaigners gathered at Clayton Park for official launch.

    In Spring 2016 the Velocity Project funded by Cycle City Ambition Grant created series of Cycle Super Highways, some on main arterials - where speed limit remains 30mph. Most of adjacent network became 20mph. £500,000 pays for implementation - again from Public Health monies.

    Much of the 20mph rollout has been allied to other transport projects improving public transport or cycling facilities funded by public health budgets. It is uncertain how much of the network is 20 mph (16- 46%). Funding is uncertain and the council "plan traffic surveys before and after the introduction of the limits to monitor results before considering whether to extend it".   "Enforcement is targeted at locations where there has been serious or fatal road accidents"  said police.

    The 20mph Champion is currently Cllr Ollie Manco. Key supporters include the Executive Member for the Environment, Cllr Kate Chappell and Transport for Greater Manchester Cycling Champion Cllr Chris Paul.

    Traffic congestion is threatening economic growth. Lower speeds are seen as key element in  encouraging modal shift away from car use towards public transport, cycling and walking.

    In May 2017 electors from ten local authorities will vote for the first Greater Manchester Mayor with police and transport responsibilities.

  • commented on Cheshire East Council to spend £1m telling drivers its not mandatory to go slower around schools and on community streets 2016-01-31 14:40:25 +0000

    Thanks for you further comment. WE don’t actually campaign for all urban roads to have a 20mph limit. We campaign that there should be a 20mph default and that any exceptions should be justified. Hence roads which have excellent segregated facilities for walking and cycling, good treatments at intersettions and crossing would not be difficult to justify.

    Of course “the child you see” is not so much a problem. Often it is the “child you don’t see” that gets killed or injured, or at least frightened. And of course children with a fear of the roads end up having no independent mobility.

    I am not aware of any places in the UK where 20mph limits are being used excessivley, but do recognise that some drivers may feel different. Perhaps it is these drivers that are the reasons why those limits are mandatory rather than advisory.

    Advisory 20mph were allowed in Scotland from 2002, but their experience has led Transport Scotland to say that advisory limits should no longer be used and mandatory limits set instead.

    2015 - The Tipping Point Year for 20's Plenty

    At this time of the year it is traditional to take stock of achievements and progress in the preceding year. For 20’s Plenty for Us then perhaps 2015 will be seen as the “tipping point” when the whole campaign took on new dimensions and success. It does not mean that in 2015 we achieved our aims of delivering a 20mph limit as the norm for all residential streets in the UK, but was the year when we started to see that that aim was going to be deliverable in the foreseeable future.
