  • DfT 20mph Evaluation - Reviewed by 20's Plenty

    20’s Plenty for Us welcomes the publication of the long-awaited DfT Evaluation of 20mph limits. It confirms the public support and acceptance of 20mph limits but has failed to meet the original DfT objectives or provide increased evidence on how to make our streets safer.

    Do you TomTom?

    ...or why unrepresentative data is not reliable.

    If you don't have a TomTom device in your vehicle then you may be surprised that if you live in one of the places recently researched by Atkins for the their Evaluation of 20mph limits then it doesn't matter how much you keep within the speed limit your considerate driving was completely ignored. And you wouldn't be alone. The report estimated that the actual number of drivers who were also ignored were in the 97% of vehicles who's speed they never measured.

    Atkins and DfT decided that in order to gather information on vehicle speeds in 20mph streets in 12 case study 20mph areas and compare them with 3 other 30mph areas then they would use data captured from high end TomTom SatNavs or vehicles with in-built TomTom in-car devices. This is termed Floating Car Data (FCD).

    You may therefore wonder just how accurate and representative their statistics and research were if it only included 3% of vehicles. We did as well, so we did some of our own research.

  • Government publishes 20mph evaluation report

    Today the government published its long awaited report evaluating 20mph limit implementations. We welcome the report. It has been a long time coming since 2014 when it was commissioned.

    And in that time there have been nearly half a million casualties on streets with a 30mph limit.

    The report only evaluated a small number of case studies which in themselves only covered part of an authority. There are some useful indicators in the report, particularly around the negative aspects of police failing to routinely enforce 20mph limits and the need for national engagement and awareness on the benefits of reducing speeds below 30mph in residential and other roads.

    However, we have major reservations about the primary data used in the report around speed reductions and the complete failure of the study to look at sufficient casualty figures to be able to draw any conclusions that would be statistically credible. These were key reasons for the commissioning of the report and we are amazed at the choice of data measured which appears to be based on measuring what is available rather than what is meaningful.

  • commented on 20mph Signage Regulation Changes 2018-09-09 18:35:22 +0100
    Dear Graham

    You will be pleased to know that on entering a 20mph limit or zone there is a large sign that is 600cm across or in diameter. In old units that is 2ft wide. Hence there is no reason why an aware driver would not notice such a sign. Its the same size as when you enter a 30mph limit. Indeed, it iss the same size as the one you say you noticed on exiting a limit.

    20mph limits are now very common and 25% off the UK population live in local authorities where 20mph is the limit on most roads. Hence a 20mph limit should not be surprising at all. May I therefore suggest that if you feel that you may well not notice such signs then you should assume that the speed limit is 20mph and only proceed faster if you have noticed a 30mph sign.

    There are no special arrangements for 20mph speeding offences. It is just like any other speeding offence.

    Hi Eddie

    The HOTA requirements may be found at http://library.college.police.uk/docs/NPCC/NPCC-(2016)-Speed-Red-light-Enforcement-Technology-Guide-v1-2-1-July2016.pdf. I see no reason why these cannot be maintained.

    It may be funded in many ways, including speed awareness courses.

    Local authorities are well versed in complying with any competition acts.

    20mph Seminar in Scottish Parliament

    I was delighted to be asked to speak at the seminar held in the Scottish Parliament building to discuss the private members bill for changing the national default limit for restricted roads in Scotland to 20mph. Local Authorities would be able to make appropriate exceptions where a 30mph limit would be retained for certain roads.

  • Bristol’s 20mph limits have led to valuable reductions in speed and casualties, and benefit active travel

    The University of the West of England (UWE) has analysed the impact of 20mph roll-outs for Bristol City Council. It finds reductions of 2.7mph in average traffic speeds and an estimated cost saving of over £15m per year from fatal, serious and slight injuries avoided.

    Dear Cllr Davies

    I am somewhat troubled by your suggestion that motorists who exceed speed limits are behaving “responsibly”. The whole point of local traffic authorities setting speed limits is that they warn drivers of risks and hazards which they may otherwise be unaware .

    By all means you may have a different opinion on what speed limit to set, and as a councillor you have every opportunity to have your opinion heard, but once set then it becomes mandatory regardless of your opinion. Any driver deeming himself or herself above the law deserves any sentence that breaking such a law involves.

    May I remind you of the long held principle in the UK that elected representatives of the people set laws, a professional police force enforces laws and an independent judiciary sentences those who are found breaking those laws.

  • commented on NICE Recommends 20mph limits Without Traffic Calming to Improve Air Quality 2017-07-29 18:48:43 +0100
    The most important thing is to be consistent. If you do something in only one place to physically reduce speeds then at the same time you are communicating that elsewhere you can and should go faster. Engineering is fine if you can do it throughout the whole network of community roads. But is the affordable or practical? Other routes to gain compliance can be engagement, enforcement. Society has a choice, carry on curbing walking and cycling from fear of traffic danger or subject non-compliers to the rule of law. Its not difficult, simply needs commitment to supporting communities and the levers to better public health, air quality, child and elderly mobility, etc.

  • commented on IAM are not so RoadSmart in their interpretation of the latest DFT report on speed limit compliance on 20mph roads 2017-07-03 18:34:04 +0100
    Other observations from the DfT report are that even on these roads with few visual clues as to the presence of people :-

    1) On 20mph roads, 37% are exceeding the limit by less than 5 mph, which is not too bad
    2) On 20mph roads, 15% are exceeding 30mph
    3) On 30mph roads, 53% of cars are exceeding the 30mph (and 25% are going more than 35mph)
    4) That means that roads with a 20mph limit have 38% FEWER cars going over 30mph!

    Or to put it even more simply, while more than half of motorists exceed 30 mph on a 30 mph road, only 15% do on (even atypical, non residential) 20 mph roads, making them substantially safer for people walking or cycling.

    P.S. If over half of all motorists are speeding on 30 mph roads does IAM conclude they’re causing confusion too?

    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.
