Speed Cameras: Designed for 20mph Limits Solutions to improve roads, journeys and communities Safer Average speed enforcement SPECS: Safer, Smoother, Greener, Fairer 300+ SPECS installations to date Smoother 50+ routes with permanent equipment 20, 30, 40, 50, 60 & 70mph limits: Safer Large KSI reductions Smoother Traffic flows improve Greener Greener Lower emissions, improved economy Fairer High acceptance, low offence levels 20mph enforcement: • Too expensive? • Not legally permitted? Fairer Solutions to improve roads, journeys and communities 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!

A common misunderstanding – it can be enforced SPECS cameras have done so, several times: • Gloucester • Tower Bridge There is a big • Upper Thames Street difference between • Blackwall Tunnel these two signs.... • Rotherhithe Tunnel ZONE • Southend Solutions to improve roads, journeys and communities Average speed enforcement speed Average Why does 20mph enforcement work? enforcement 20mph does Why %age of vehicles • 10.00% 15.00% 20.00% 25.00% 0.00% 5.00% Behaviour at overt SPECS enforced locations predictable: is locations enforced atBehaviour overt SPECS 0 5 10 15 20 25 30 35 40 45 Solutions to improve roads, journeys and and communities journeys roads, improve to Solutions 50 55 60 65 70 75 80 85 90 50mph 40mph 30mph 20mph 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 Solutions to improve roads, journeys and communities 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 Solutions to improve roads, journeys and communities 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. Solutions to improve roads, journeys and communities 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 Solutions to improve roads, journeys and communities 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 Solutions to improve roads, journeys and communities 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 Solutions to improve roads, journeys and communities 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? Solutions to improve roads, journeys and communities 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? Solutions to improve roads, journeys and communities 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 Solutions to improve roads, journeys and communities 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 Solutions to improve roads, journeys and communities 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 Solutions to improve roads, journeys and communities 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 Solutions to improve roads, journeys and communities Solutions to improve roads, journeys & communities GeoffSolutions Collins to improve [email protected], journeys and communities .
