20mph in Bristol

Success of 20mph speed limits in Bristol

Bringing in a blanket 20mph limit across Bristol has cut the speed of traffic, saved lives and should be used as an example for other places in the country.

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.

20s Plenty for Us

Myth Busting Shire Counties

Many of the shire counties, which includes Worcestershire, have been behind the urban authorities in implementing 20mph limits. The following summarises a blog on the main 20s Plenty for Us website.

Already the majority of the largest 40 urban authorities have adopted a Total 20 policy. And also 75% of Inner London boroughs.

Some county councils seek to “manage expectations” by adopting policies that are not consistent with DfT guidance in an attempt to dampen down the legitimate aspirations of communities for lower speeds. That isn’t to say all shire counties. Indeed Lancashire has already implemented Total 20 and also Bath & North East Somerset is progressing in its roll-out. Also other places with rural parts or outlying villages are implementing Total 20 in villages. Sefton and Warrington are examples. But it is clear that many shires seem ideologically opposed to 20mph limits in their communities. Continue reading

20mph: A Litmus Test of Public Health Outdoors

Road injuries hurt an estimated 1% of people a year and its rising. Tackling road risk is key to public health improvement outdoors for all ages. Community-wide 20mph limits confer huge health economic returns in casualties avoided and in active travel exercise gains.

194,477 people were recorded road injured in 2014 (a 6% increase over 2013). Including unreported casualties 700,000 (1%) of Britons are estimated road injured yearly. The vast majority involved motorists hitting people. Adding those too frightened to play out, walk or cycle and underactive makes a staggering illness burden from predictable and preventable road risks.  The Department for Transport (2011) estimated that including incidents unreported to the police the value of preventing road crashes was £34.8 billion per year – a whopping £540 per head pa.

With residential 20mph limits Warrington reported a First Year Rate of Return of 800% – the capital costs were recovered in reduced casualty value in just 7 weeks. 20mph limits are a once off cost of approx. £2-3 per head and typically avoid 20% of casualties for years to come.

Wide 20mph limits are best practice according to the World Health Organisation, NICE, Association of Directors of Public Health, Faculty of Public Health, UK Public Health Association, Royal College of Paediatrics & Child Health and National Children’s Bureau. 20mph is an evidence-based, cost effective policy whose lower risk and fitness benefits far exceed its costs.  Bristol estimated a £24 per £1 spent benefit to cost ratio on increased walking and over £7 on raised cycling.  Implementation is typically £0.5m per 200,000 population and discounted across future years.

For children, the elderly and health equality for age groups, Britain’s top outdoor public health priority is tightly monitored road danger reduction plans with targets and tight recording (like workplace injuries) with careful reflective learning and application of evidence-based danger mitigation measures.  Proven prevention policies include 20mph limits for built up areas (each 1mph less reduces crashes and casualties 6%), low alcohol tolerance levels, speed enforcement, hidden cameras, in vehicle speed limiters, presumed liability, no texting whilst driving and a Vision Zero (no deaths) goal. We know the solutions. What we need is the multi-agency working, finance and political will to apply them.

20mph It’s miles better! The conference at the heart of the 20mph revolution

Milan is the latest European city to say that 20’s Plenty, or more precisely 30k – Its OK

In the UK we are at the heart of that change with over 20% of the population in places that have or are implementing a 20mph limit for most roads.

The 6th Annual 20mph Places conference is in the Guildhall, Cambridge on 12th March and at a cost from just £125* this could be the best investment made all year.

  • It brings together presenters showing best practice implementations of city-wide 20mph limits in some of our major iconic conurbations.
  • It develops the public health and public sector equality benefits
  • It shows how it is a foundation for a cycling revolution and an urban renaissance.

Learn how 20mph limits go far beyond road safety and tick the many boxes for liveability, active travel, modal shift, noise reduction, casualty reduction and a real saving in future public health costs. Learn how funding can come from many sources rather than transport or road safety. Understand how your PSED relates to setting speed limitsFor Councillors

For officers and consultants in transport and public health

Gain from the real experience of implementations in Cambridge where zones with physically calmed entrances are leading the way in hybrid zonal 20mph limits. Find out about the large roll-out in Manchester and it promotion of community ownership. Learn how Liverpool with their 20Effect programme are leveraging city-pride and identity to make their roll-out successful. See how Calderdale are bringing public health and transport teams together to maximise behaviour change.

For everyone

Hear the keynote presentations and discussions from the leaders in cycle advocacy and pedestrian representation. Chris Boardman MBE and Joe Irvin.

You can download a conference leaflet from’s_miles_better.htm and make a direct booking at

* £125+vat rate for public sector booked before 17th Feb. See above links for full delegate rate range.

20mph Myth Buster

Opponents of wide-area 20mph speed limits rely on various myths that need to be busted! Have a look at some of the myths and the reality below.

Myth: 20mph journey times are far greater than 30mph.
Reality: 20mph doesn’t significantly alter trip times or inconvenience drivers. Traffic jams and stops do. Constant 30mph is rare due to bends, junctions etc. Going fast between obstructions = extra wait at next stop.

Myth: 20mph is OK near schools in term time at drop off and pick up times only.
Reality: 80% of child casualties happen non-school trips. Families need wide area limits for child protection from road injury – their top risk.  Older people are even more likely to die or be seriously injured – 20mph is 10 times safer (than 30mph) for 60+yr olds compared to 7x for others.
