The 73-year old who started Britain's 20mph revolution

Reprinted from THE SUNDAY TIMES 24th September 2023 A grassroots campaign that started in a terrace in Cheshire has achieved a big milestone with Wales’s new limit. It’s only a matter of time before the whole UK follows suit, says its founder Continue reading

20mph Speed Limits in London - Update for Action Vision Zero

Action Vision Zero campaigners in London were given an update on 20mph sped limits in London. This presentation included status of London Boroughs, TfL roads and enforcement. Continue reading

Speed limits of 20mph in built-up areas will become the “default” for drivers across Britain in a matter of years, the architect of the policy in Scotland has said.

Mark Ruskell, who proposed a Bill at Holyrood to make 20mph the standard on residential streets in Scotland in 2019, said a “generational shift” was already happening. In an interview with i-news, the Scottish Green MSP said the UK had reached a “nationwide tipping point” on the issue and that he believed most residential streets would soon be 20mph.

Belfast 20mph should be city-wide like Edinburgh rather than city-centre

A new report highlights that how implementing 20mph over a small area in Belfast where speeds are already below 20mph is far inferior to the established experience from city-wide schemes that reduce speed and casualties significantly. Hence this report gives little insight into the success of setting 20mph as an urban/village norm other than showing how not to implement it. The implementation in Belfast was on just 76 streets in the city-centre on which the average vehicle speed was well below 20mph. Of these 76 streets, 27 were already fully or partially pedestrianised. At the same time other travel initiatives included the introduction of a rapid transit system and extension of the city-centre bus lane provision. There was also little community engagement or marketing of the 20mph scheme. Such an isolated and small implementation which keeps 30mph as a norm on all the other streets in the centre was always going to result in little change and this report confirms this. In fact other reports which compared Belfast with Edinburgh and its city-wide 20mph scheme show just how more effective 20mph schemes are when implemented city-wide. Continue reading

Spain cuts casualties by 20%

Spain's Minister of the Interior has presented the consolidated data on road accidents for 2021 in Toledo to value the work carried out by municipalities in terms of road safety In 2021, 417 people died on urban roads, 102 fewer fatalities than in 2019, a reduction in mortality of 20 percent in a single year unprecedented in the historical series Grande-Marlaska: “When explaining this significant reduction in road mortality in our cities last year, I want to remember that on May 11, 2021, the speed limit of only 30 kilometers per hour on city streets came into effect. one lane in each direction of travel The decrease in deaths in cities has been reflected in vulnerable users with a 34% reduction in cyclists, 31% in deaths over 64 years of age, 26% in pedestrians and 17% in motorcyclists Continue reading

Presentation to West Midlands Strategic Police and Crime Board

Last week I was invited to give a presentation  at a session on Active Travel of the West Midlands Strategic Police and Crime Board. One of the most important aspects for vulnerable road users is the speed of motor vehicles, so I used the opportunity to present the benefits of a wider, citizen-led approach to speed management and enforcement using the Speedcam Anywhere app. The transcript of my 5 minutes presentation follows: Continue reading

Why we need 20 mph speed limits if the changes to the Highway Code are to work

We feel that this guest blog is particularly relevant to the update to the Highway Code. It explains the changes and also how default 20mph limits are complementary to these changes. Thanks to Carl Waring of Mooneerams for their perspective. After a decade without revision, a statutory instrument laid before Parliament last December finally paved the way for a raft of new rules to be introduced into the Highway Code on January 29th.  The Department for Transport (DfT) believes that the changes to the Code will Improve safety for vulnerable road users by giving them priority in potentially dangerous situations on or near the highway.

Members of the public may comment until 31st Jan 2022 on the Cheshire East website here. We advise rejection of the Strategy on several counts.   Continue reading

The 25mph Conundrum

Many people ask what to do if the average speed on a road is 25mph or above. Can you set a 20mph limit? Lets consider what I call "The 25mph Conundrum". Setting speed limits based on what drivers think is the right speed is a flawed approach. This is considered in a recent report from NACTO (National Association of City Transportation Officials). It concludes that "Relying on a percentile-based system focused on current driver behavior, rather than a defined safety target to set speed limits, significantly limits cities’ ability to reduce traffic deaths.   So lets go through the logic of solving this conundrum for UK situations.   Continue reading

Why not "self-explaining" roads?

I have been having a discussion on LinkedIn with some engineers on the choice of building "self-explaining" roads rather than wide-area speed limits after posting this infographic.  My response was rather too long for the usual character limit on LinkedIn, hence it initiated this blog.

Our response to Scotland's Road Safety Framework to 2030 Consultation

The Scottish Government has published its Road Safety Framework to 2030 Draft for consultation. We applaud the vision within this that "Our vision is for Scotland to have the best road safety performance in the world by 2030."  Scotland's road fatalities per million population stands at 30 this is considerably greater than leaders such as Iceland at 17 and Sweden at 22. Whilst such a radical vision is laudable we are concerned that the plans are not radical enough to catch up and overtake other countries in terms of road safety. Our response to the consultation points out that much more must be done if Scotland's performance is to match its' aspirations. It makes particular reference to speed management.  Continue reading

Article for Road Safety Markings Association Magazine

We were asked to write an article for the annual Road Safety Markings Association's annual magazine. 20’s Plenty – for the 2020’s A few year’s ago I had the pleasure of speaking at the RSMA annual conference and noticed the strong commitment to making our streets safer. In that I explained how the movement for slower speed limits on community streets was evolving. The 20’s Plenty (or Love 30 as it is known in km/h countries) was making great progress this year even before the Covid-19 pandemic and the realisation that we all needed more space and safety to move around our cities, towns and villages.

Communications with the government on default 20

Since launching our campaign on April 9th in support of doctors calling for an emergency default 20mph urban speed limit we have had a number of communications with MPs. ministers and DfT officials. This provides a useful insight into the thinking of the government and its attitude to speed limits. The emails and letters are provided along with our responses.   Continue reading


Some of you may have seen the weekend papers which ran stories on this report from Queen's University Belfast. In fact the report in the Queen' s University website had exactly the headline shown above. It was a report that reviewed available previous research on 20mph zones and limits. It reviewed 9 20mph "Zone" reports and 2 20mph "limit" reports. Its conclusion was :- "This review suggests 20 mph ‘zones’ are effective in reducing collisions and casualties. However, it provides insufficient evidence to draw conclusions on the effect of 20 mph ‘zones’ on pollution, inequalities or liveability. For 20 mph ‘limits’ more rigorous evaluations are required in order to draw robust conclusions." Basically it was saying that the 2 reports used on 20mph were not thorough enough to draw "robust" conclusions. One of these reports was the Atkins report which we have also criticised for not being thorough enough to be meaningful. Much of our criticism of Atkins can be seen in a previous blog where we call-out the questions which still need to be answered.   Continue reading

Transport in the 2020s

Change is palpable on our streets.  Trends show a huge rise in electrically assisted transport like e-bikes. Politicians valuing health are increasingly valuing the role of walkers, e- and folding bikes and scooter riders in accessing towns sustainably. Providing primarily for private cars isn’t smart – they’re jammed up, dangerous, dirty, climate damaging and an inefficient use of city space to drive or park.  The safe movement of people matters more than solo driver convenience.  Continue reading

There can be no keener revelation of a society's soul than the way in which it treats its children

I was asked to write a blog for BRAKE's 2019 Road Safety Week. I started with what I think is an inspiring and very relevant quote from Nelson Mandela :- "There can be no keener revelation of a society's soul than the way in which it treats its children." And that must be the question we ask of politicians. Who do they treat better: The child who wants to walk or cycle to their school or the adult who wants to drive to work? Continue reading

Bradford City Centre 20mph limits go live

Today we were asked by Bradford Council to a provide a supporting statement to their press release. This is what we suggested :- “20mph limits are the global standard where pedestrians and cyclists mix with motor vehicles. This is supported by the World Health Organisation, OECD, and many global and national NGOs. In many countries, 30km/h (18.5mph) limits are standard across cities, towns and villages. Already 21m people in the UK live in authorities that have already set or are setting 20mph for most residential and city centre streets. 20mph becomes the norm rather than the exception. This delivers across a wide range of city aspirations including reducing road danger, enabling active mobility, child mobility , elderly mobility and reducing emissions and car-dependency. It is good to see Bradford Council adopting 20mph limits, and we would urge it to go further and deliver a 20mph street environment as the norm for all its residential roads across the whole district.”    

Beware Irrelevant DfT Data on Speeding in 20mph Limits.

Blog by Anna Semlyen 20’s Plenty for Us National Campaign Manager June 2019 At the end of June, the Department for Transport (DfT) report some irrelevant statistics on speeding[1]. Note firstly that the 10 sites of 20mph roads are unrepresentative free-flow locations with no traffic calming or other speed restricting features which tend to be through-roads.  Yet most 20mph limits are side roads.   [1] Continue reading
