20 mph - The Cambridge ExperienceJohn RichardsActing Project Delivery & Environment Manager

Background to Cambridge 20 mph Challenges facing City’s
infrastructure: Compact city of 120,000 residents,
seasonal students and visitors Historic core Highest cycling rates in UK Road casualties Growth, congestion and pollution
Existing 20 mph areas have proved popular!
![Page 3: Jr 2015 national 20mph conference presentation](https://reader035.fdocuments.in/reader035/viewer/2022062522/5879a4eb1a28ab082c8b6af7/html5/thumbnails/3.jpg)
History Early safety driven schemes date from
late 80s/early 90s Engineering ‘heavy’
Awareness of changing national landscape around lower speeds
2010 ‘Trial’ schemes based on signing/road markings alone Central area within
inner ring road Wulfstan Way /
Gunhild Way late 1940s residential estate

Objectives
City-wide 20 mph consistency, rationalise existing areas and signage
Facilitate active and sustainable travel modes Health and congestion benefits
Improve safety and feeling of security Reduce noise and pollution Environmental improvement

New beginnings… Project established through 2011
motion to Council City-wide approach Cross party support £600k Capital budget over 3 years Light not heavy handed approach,
based on signing and road marking changes
Self enforcing
![Page 6: Jr 2015 national 20mph conference presentation](https://reader035.fdocuments.in/reader035/viewer/2022062522/5879a4eb1a28ab082c8b6af7/html5/thumbnails/6.jpg)
Consider the function of streets and 20 mph as a catalyst for potential change…
![Page 7: Jr 2015 national 20mph conference presentation](https://reader035.fdocuments.in/reader035/viewer/2022062522/5879a4eb1a28ab082c8b6af7/html5/thumbnails/7.jpg)
Routes for movement…
‘Thoroughfare’ dominates e.g. ‘A’ and ‘B’ category roads generally unsuited to 20 mph…
![Page 8: Jr 2015 national 20mph conference presentation](https://reader035.fdocuments.in/reader035/viewer/2022062522/5879a4eb1a28ab082c8b6af7/html5/thumbnails/8.jpg)
Routes for access…
Thoroughfare less dominant e.g. residential and shopping streets generally suited to 20 mph…
![Page 9: Jr 2015 national 20mph conference presentation](https://reader035.fdocuments.in/reader035/viewer/2022062522/5879a4eb1a28ab082c8b6af7/html5/thumbnails/9.jpg)
But what about those in between?
e.g. ‘C’ class or distributor roads
these are different sections of same road….
![Page 10: Jr 2015 national 20mph conference presentation](https://reader035.fdocuments.in/reader035/viewer/2022062522/5879a4eb1a28ab082c8b6af7/html5/thumbnails/10.jpg)
Recommendations based upon:
Function of route within hierarchy
Road and traffic characteristics Existing traffic speeds
(comprehensive surveys) Levels of public support
![Page 11: Jr 2015 national 20mph conference presentation](https://reader035.fdocuments.in/reader035/viewer/2022062522/5879a4eb1a28ab082c8b6af7/html5/thumbnails/11.jpg)
Approach
Phased implementation over 2-3 years
Efficient mix of zones and limits Engagement centred around 4 Area
Committees 132 miles, or 85% of city’s roads, included Project Board aligns key stakeholders and processes
(e.g. County Council as Highway Authority)
![Page 12: Jr 2015 national 20mph conference presentation](https://reader035.fdocuments.in/reader035/viewer/2022062522/5879a4eb1a28ab082c8b6af7/html5/thumbnails/12.jpg)
High Public Engagement expectations Approx. 60,000 consultation
packs delivered to all city addresses
Project web page and online questionnaire
Public exhibitions Press releases and social
media Area Committee and
Environment Scrutiny Committee consideration
Opportunity for public to have say and help shape – encourages ownership
![Page 13: Jr 2015 national 20mph conference presentation](https://reader035.fdocuments.in/reader035/viewer/2022062522/5879a4eb1a28ab082c8b6af7/html5/thumbnails/13.jpg)
Consultation headlines Approx. 11,000 responses, 18%
return rate < 4% non city residents > 2 to 1 in favour Mixed support on ‘C’ road suitability Key concerns: enforcement and
worsening congestion Popular misconceptions
![Page 14: Jr 2015 national 20mph conference presentation](https://reader035.fdocuments.in/reader035/viewer/2022062522/5879a4eb1a28ab082c8b6af7/html5/thumbnails/14.jpg)
Implementation Progress
Phase 3 (South and West /
Central areas)consultation completed, member review, target implementation next
12 months
Phase 1 (North area) completed
Phase 2 (East area)
TROs in place, implementation
Spring 2015

Victoria Road A busy ‘A’ class route forming part of the city’s inner ring road Considered ineligible for 20 mph given County policy that excludes
‘A’ and ‘B’ class roads Road and usage characteristics similar to many ‘C’ class routes
included Public demand and political support Agreement to advertise, objections determined (by County Council)
and now included within project scope
![Page 16: Jr 2015 national 20mph conference presentation](https://reader035.fdocuments.in/reader035/viewer/2022062522/5879a4eb1a28ab082c8b6af7/html5/thumbnails/16.jpg)
Post implementation monitoring (north area) On 93% of streets previously above
20 mph, speeds have reduced Average reduction 1-2 mph typical 3 mph reduction on a busy ‘C’ road
(Arbury Road) Average speeds on roads included
now below 24mph, with 56% below 20mph
![Page 17: Jr 2015 national 20mph conference presentation](https://reader035.fdocuments.in/reader035/viewer/2022062522/5879a4eb1a28ab082c8b6af7/html5/thumbnails/17.jpg)
Further work Complete city-wide (realise
maximum benefit) Marketing (hearts & minds) and
promotion Enforcement (carrot and stick) Monitoring of:
Travel choices Traffic speeds Casualties Air quality and noise Public perceptions, and satisfaction?

Development phase learning Ensure sound evidence base Adequately resource, plan and
programme Establish governance and
processes Challenge assumptions Flexibility around road and user
characteristics rather than classification

Future challenges Scrutiny around ‘value for money’ Compliance and need for enforcement Public acceptance and ownership Maintaining advocacy message Dealing with inconsistencies and
problem streets Project integrity What next?

Consider widespread 20 mph coverage as a step change in public attitudes around healthy, living, cities
And finally…
