20 mph Speed Limits in Middlesbrough Rob Farnham Principal Engineer, Parking and Traffic Engineering Middlesbrough Council Background • ‘Best ever’ casualty totals in 2010: ten-year targets achieved, with KSI casualties reducing from 85 in 2003 to 30 in 2010 - and no fatalities. • Desire to maintain downward momentum in future years despite major cuts in capital and revenue funding.

How do Area-Wide 20 mph Speed Limits Work? • By changing drivers’ attitude towards speed in residential areas – and, therefore, their behaviour. • Introducing a 20 mph speed limit on an individual road or a single estate has only a marginal effect on vehicle speeds. • However, adopting an area-wide or ‘blanket’ approach is much more effective, as 20 mph effectively becomes the ‘default’ speed limit in residential areas across the Borough. Scheme Development • Atkins commissioned to carry out study into feasibility of area-wide 20 mph speed limits in Middlesbrough in February 2010. • Consultation held in May 2010 with Community Council ‘Cluster Groups’ on principle of area-wide 20 mph speed limits – general support for proposal. • Principle of area-wide 20 mph speed limits adopted by Council in February 2011, based on a prioritised, three-year implementation programme.

Consultation • Given the scale of the scheme, not practical to consult individual residents. • All 25 Community Councils within Middlesbrough consulted on the proposed 20 mph speed limits within their area. Strong support for the proposals, with 24 out of 25 voting in favour. • Extensive coverage in local media, in particular the ‘Evening Gazette’. Legal Process • Two Traffic Regulation Orders advertised, covering a total of 1,365 streets. • Notices placed in ‘Evening Gazette’ and on Council website. No statutory requirement to post notices on site. • A total of four objections received, all for first Order. All four objections overruled by the Executive Member for Streetscene Services and Transport. Implementation Programme • Scheme originally programmed for implementation over three years. However, additional funding subsequently made available to reduce programme from three years to two. • Implementation of Phase 1 – covering 678 streets in Acklam, Beechwood, Berwick Hills, Brookfield, Easterside, Linthorpe, North Ormesby, Park End and Tollesby – carried out between January and July 2012, with official launch on 10 July 2012. Implementation Programme (2) • Implementation of Phase 2 – covering the remaining 687 streets, including all of the residential areas across the south of the Borough including Coulby Newham, Hemlington, Marton and Nunthorpe – commenced in March 2013 and is currently ongoing. • Works programmed for completion by the end of May 2013. • All works carried out by Streetscene, the Council’s in-house contractor. Signing and Road Markings • ‘Gateway’ treatment at entry points, comprising a pair of terminal signs and a roundel on the carriageway, similar to the approach adopted in Portsmouth. • 20 mph repeater signs erected at approximately 200 metre intervals on roads covered by the new limits, making use of existing lighting columns to reduce street ‘clutter’. • No legal requirement to illuminate terminal signs. Cost of Scheme • Overall budget £219K: – Phase 1: £67K. – Phase 2: £152K. • Cost of advertising Traffic Regulation Orders c. £12K. • All costs met from Council’s 2011/12 and 2012/13 LTP Integrated Transport allocations. Education v. Enforcement • General approach is to encourage drivers to travel more slowly in residential areas rather than punishing drivers who break the new limits. • Police have adopted a ‘hands off’ approach – no commitment to enforce 20 mph speed limits. • Camera enforcement not currently an option. • Use of vehicle activated signs and Community Speedwatch to encourage compliance. Monitoring and Evaluation • Limited evaluation carried out to date – Phase 1 went ‘live’ less than a year ago. • Initial results show that average speeds within the Phase 1 area have typically reduced by between 1 and 2 mph, consistent with the experience in Portsmouth. • Further speed monitoring to be carried out over the coming months. • Casualty statistics also being monitored. Conclusions • Strong public support for the 20 mph speed limit scheme. • Overall cost of implementation similar to that originally envisaged. • Initial results encouraging, although further monitoring and evaluation needed. • Longer term outcome in terms of the number and severity of casualties still to be established.
