  • Email your MP to support UN Global Road Safety Week

    The UN are calling for 20mph or 30km/h speed limits to become the norm in places where people on foot or on bicycle mix with motor vehicles. It is the key focus of the 6th UN Global Road Safety Week running from 17th-23rd May.

    This is backed by science and the call from communities to set speed limits that are compatible with liveable communities.

  • It is smart for national governments to set national urban/village default speed limits of 20mph or 30km/h.

    Local governments in towns, cities and villages around the world are rejecting nationally set 30mph or 50km/h speed limits as no longer “fit for purpose” in meeting the needs of citizens and society. 20mph or 30km/h is now seen as the maximum safe speed limit where motor vehicles mix with pedestrians and cyclists unless there are adequate segregated and crossing provisions. 

    National governments should set 20mph or 30km/h as their national default urban/village speed limit.

    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.

    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.

  • National and local governments are setting 20mph limits; why you should do the same

    A nearly universal aspiration in communities is to make traffic speed compatible with community life and human survivability.  A 30mph limit is no longer fit for purpose for urban and village streets. Lower default limits are being set. Choose 20mph.

    20mph is low cost and brings wide benefits

    Among urban and village improvement options, 20mph ranks top for cost effectiveness. Over a wide area, 20mph benefits all road users and the whole community. Casualties fall 20%[1], noise almost halves and active travel rises. Councils can afford it.

  • 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.

  • 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.

    Hi Miranda

    Yes. The heart shape is clearly not a road sign. It uses a different shape in being a heart instead of a circle, it is a “broken heart” in that it is not continuous" and includes the word “mph”. It also has a clear campaigning message. It does not “direct” drivers to drive at 20mph. Hence it cannot be confused with or interpreted as a road sign.

    The signs have been bought and used by campaigners and parish councils in their thousands for use in areas that are campaigning for the Traffic Authority to set a local 20mph speed limit in place of the national 30mph limit.

    The signs are usually used on private land or on Wheelie Bins.

  • Darker Nights: 20mph Widens Fields of Vision and Halves Stopping Distances to Effectively Mitigate Risk At Source

    Clocks go back Sunday 25 October meaning darker nights. Sunset will be from 4.45pm and nightfall from 6pm.  20mph limits widen drivers’ fields of vision. This helps see hazards and take avoiding action earlier. Drivers can stop in half the distance compared to 30mph. 20mph reduces the kinetic energy with fewer deaths or life changing injuries.

    So you want... children to go out

    Children used to roam further than now. There’s COVID yes, but they still need to go places alone. Traffic fear is key.  Wide 20mph limits enable kids to get out - to relatives, friends, parks, shops, play, walk, scoot and cycle.  Confident, sociable, independent, healthy, active travel habits form on safer streets. Obesity, anxiety and loneliness reduce.  Families lead better lives. They say “it takes a village to raise a child” – and that’s so much better with a 20mph limit.

    20mph County Campaigning Options

    Organising a 20mph campaign at county council level has many advantages. Our new email a decision maker facility will  work best when communities across an authority work together. There’s power in numbers and especially in focussing on updating policy rather than competing to be a 20mph exception in an otherwise 30mph county.

    Webinar 25th June 2020 - 20's Plenty for Us

    With less traffic on our roads recently, local authorities have been instructed by the Department for Transport to re-allocate road space for walking and cycling – but it’s unclear how long these schemes will last. Worryingly, there is also evidence to suggest that speeding is on the increase on less congested roads. Many local authorities are considering implementing 20mph limits to enable citizens to use streets, roads and public space safely.

    There are also calls for a national default 20mph limit from doctors and many local authorities. The Welsh Government has announced a plan to change its national default urban limit to 20mph. The UK government recently signed the Stockholm Declaration resolving to set 30km/h (20mph) limits as a default where cyclists and pedestrians mix with motors.

    This free webinar was held on Thursday 25th June, organised by Landor Links, and explored:

    • How national 20mph limits could be implemented
    • Health perspectives: road casualties and understanding the load on the NHS
    • How to actively consider roads for 30mph suitability
    • Setting default 20mph limits across cities and regions
    • Communication, information and enforcement
    • Consultation and feedback: community views of 20mph limits
    • Current and future funding opportunities: signing, lining and traffic calming measures
    • Motorists’ behaviour change opportunities
    • What’s happening across the world
    • The role of Intelligent Speed Assistance (speed limiters), mandatory on all new car models from 2022
