1. Bristol’s 20 mph experience Peter Mann Service Director, Transport

2. A road speed revolution
Cities and boroughs across the UK are adopting 20 mph limits for road safety and other reasons
Tackling road safety, promoting local communities, improving public health
Increasing awareness of the key facts around speed and collision occurrence as well as injury/risk of death

3. Aims (in line with the Casualty Reduction To improve road safety
targets)
To encourage more people to take up walking & cycling (to increase total physical activity time)
To increase social cohesion (with more activity on streets)
Aims

4. Piloting 20 mph in Bristol
Two pilot schemes September/October 2010:
Inner South Bristol (Southville, Bedminster, Windmill Hill)
Inner East Bristol (Easton and St Pauls)
Between them they covered 500 roads and 30,000 households with a sign only speed limit
Funded from Cycling City – DfT funded programme (£382k + £98k for pre and post monitoring)

5. A road speed revolution
Cities and boroughs across the UK are adopting 20mph zones for road safety reasons
They include: Oxford, London Borough of Islington, Lancashire, Warrington, Liverpool, Portsmouth and many more.

6. A road speed revolution
Cities and boroughs across the UK are adopting 20mph zones for road safety reasons
They include: Oxford, London Borough of Islington, Lancashire, Warrington, Liverpool, Portsmouth and many more.

7. Piloting 20 mph – the results
The results were overwhelmingly positive:
82% of local residents in the pilot areas supported 20mph
65% of roads saw a reduction in average speeds
There was a % increase in walking and % increase in cycling
HEAT showed the return on investment of 24:1 walking, 7:1 cycling

8. Citywide 20 mph roll-out The pilots were deemed a success
July 2012 Bristol City Council voted to extend the 20 mph speed limit to all residential streets in Bristol
A study, carried out by Bristol Social Marketing Centre at UWE, was also commissioned to establish the most effective ways to implement the change – these included:
…have a vision, get political support, allocate a budget, use the right skills, agree shared outcomes, avoid alienating drivers, be patient, be visible, communicate success

9. Public Consultation
Extensive informal public consultation sought views on proposed 20 mph speed limit
Feedback via the Council’s “Ask Bristol” website
Public library and local shopping centre exhibitions, supported by officers
Key role of Neighbourhood Partnerships (14 across city)
Information made available online, in local press, via a postcard drop to all households and posters in local shops and community buildings

10. Citywide 20 mph - the details
Dual carriageway and 40 mph and 50 mph roads not affected
All other roads designated as 20 mph
Sign only scheme with no physical traffic calming measures
Scheme cost £2.3 million funded from Local Sustainable Transport Fund (LSTF) and Local Transport Plan capital

11. Citywide 20 mph - The fast track roll-out
Phase 1 – January 2014
Phase 2 – July 2014
Phase 3 – September 2014
Phase 4 – March 2015
Phase 5 – June 2015
Phase 6 – September 2015

12. Achieving 20 mph - Engagement programme
Vital to ensure as many people as possible knew of the new speed limit, so we:
Ran campaigns to raise the profile of 20mph
Talked about concerns, fears and the benefits of 20mph
Presented to Neighbourhood Partnerships and other community groups
Worked with schools, driving schools and businesses

13. Achieving 20 mph - Signs and road markings
Solar-powered vehicle activated signs used to remind drivers of the new speed limit
Large road signs installed at key junctions where the speed limit changes

14. Monitoring
Extensive monitoring through to June outcome report, using:
traffic surveys to record volumes and speeds
casualty data
household interview surveys
qualitative feedback from local councillors and Neighbourhood Partnerships

15. The Future Mayoral commitment to review 20 mph
No plan to reverse, but to address local concerns and anomalies
Use maintenance and traffic management programmes to adapt the highway network so 20 mph is better integrated– e.g. centre-line removal, tightening junctions
Continuous engagement - twitter @bristol20mph Facebook/20mphBristol

16. Lessons learned – so far
Always go back to the evidence
Monitoring is phased too
Social marketing is key
The challenge of the “main roads”
And finally – a plug…
…Traffic Choices
