1 Speed Cameras: Designed for 20mph Limits

2 Safer Average speed enforcement SPECS: Safer, Smoother, Greener, Fairer 300+ SPECS installations to date 50+ routes with permanent equipment 20, 30, 40, 50, 60 & 70mph limits: Smoother Safer Smoother Greener Fairer Large KSI reductions Traffic flows improve Lower emissions, improved economy High acceptance, low offence levels Greener 20mph enforcement: Too expensive? Not legally permitted? Fairer

3 SPECS3 : widely implemented & understood Since HOTA in 1999, over 200 temporary and 30 permanent SPECS1 projects Since HOTA in 2009, over 50 temporary and 25 permanent SPECS3 projects with 14 SCPs Operated with 20, 30, 40, 50, 60 and 70mph schemes Not a new concept and not just in roadworks! SPECS3 Location SCP SPECS3 Location SCP M3 / M25 junction Surrey A611 Annesley Nottinghamshire A60 Mansfield Road Nottingham A3 Hindhead Tunnel Surrey M25 QEII Bridge Essex A130 Canvey Way Essex A282 & M25 J2 - Dartford tolls Kent A14 Girton to Fen Ditton Cambridgeshire Blackwall Tunnel London A537 Macclesfield to Buxton Cheshire Aspley Lane Nottingham A52 Ropsley Lincolnshire A374 Plymouth Devon & Cornwall Marine Parade, Southend Essex B1096 Forty Foot Drain Cambridgeshire A38 Shenstone to Bassetts Pole Staffordshire A66 Bass Lake Cumbria A614 Old Rufford Road Nottinghamshire A149 Sutton Norfolk A465 Head of the Valleys Wales A631 Beckingham Nottinghamshire A55 Britannia Bridge Wales A6097 Epperstone Bypass Nottinghamshire A61 Sheffield South Yorkshire

4 Can 20mph be enforced? A common misunderstanding it can be enforced SPECS cameras have done so, several times: Gloucester Tower Bridge Upper Thames Street Blackwall Tunnel Rotherhithe Tunnel Southend ZONE There is a big difference between these two signs...

5 %age of vehicles Average speed enforcement Why does 20mph enforcement work? Behaviour at overt SPECS enforced locations is predictable: 25.00% 20.00% 15.00% 10.00% 20mph 30mph 40mph 50mph 5.00% 0.00%

6 Southend case study Part of a shared space installation Guardrails & pelican crossings removed Paving, water features & lighting installed SPECS3 POD installation Enforces a 20mph speed limit NOT a 20mph zone Street furniture always in place Enforcement device relocated Different sections can be made live Alternative routes can be managed

7 Southend case study System designed to be appropriate Not 6m tall cantilevered columns First use of urban column POD devices can be moved without impact on compliance

8 Lighting Don t want flashes or intense puddles of bright white lighting: Recent images taken on the A614, Nottinghamshire from a new SPECS3 POD installation. Uses additional Infra Red (IR) flood lights on an unlit road.

9 20 mph Area Design Concepts There are several ways a zone could be covered: Cameras at all entry & exit points Cameras throughout the monitored zone Cameras supporting engineering measures

10 20 mph Area Design Concepts There are several ways a zone could be covered: Cameras at all entry & exit points Cameras within the monitored zone Cameras supporting engineering measures

11 20 mph Area Design Concepts There are several ways a zone could be covered: Cameras at all entry & exit points Cameras throughout the monitored zone Cameras supporting engineering measures

12 20 mph Zone Design Concepts There is no blanket solution Every zone has its own local issues Where are the hazards / casualties? How do people drive through the zone? What are the traffic volumes on each link? Camera technology plays a part Speed cushions, chicanes, humps may complement them Change to access and priorities Vehicle activated signs Would drivers change their route?

13 Operational Issues There are some significant issues to address 20mph limit vs 20mph zone Needs further consideration Police operational policy Some forces don t like to enforce 20mph Cost to install and operate How is the cost justified and paid for? Clutter vs deterrent Balance between conspicuity & street scene Enforcement levels How many tickets are too many?

14 Future System... A new generation is soon to achieve Home Office Type Approval SPECS3 Vector Reduced installation cost Lower power requirement High resolution Revised approval, not a new device Fully compatible with SPECS3

15 Bi-directional monitoring SPECS3 Vector can monitor both directions on a single carriageway road Forward-facing in one direction Rear-facing in the other direction Reduced minimum baseline of 75m between cameras 250m minimum for standard SPECS3

16 New street furniture A new generation of columns / mounts: Lightweight construction Smaller but distinctive Passively safe SPECS3 VECTOR fully integrated module No roadside cabinet Fit for urban application Can be fitted to existing columns

17 Summary 20mph limits can be enforced Legally and technically, it can be done The tools are now right Must be a site specific design Caution! Must be clear on why it is being done Not to be entered lightly Cameras only part of the answer
