What do we do?
One stop service for integrated ANPR solutions.
• hardware & software development• Consultation on solution design• Full installation service• Support & maintenance
Solutions to improve roads, journeys and communities
Vysionics World Firsts
1979 - First ANPR reader
1983 - First automatic plate detection ANPR system
1989 - First ANPR based journey time measuring system
1996 - First ANPR security cordon (City of London ring of steel)
1999 - First HOTA average speed system - SPECS
2002 - First ANPR congestion charging system (London)
2009 - First VCA approved automated bus lane enforcement
2009 - First HOTA networked average speed – SPECS3
Solutions to improve roads, journeys and communities
SPECS : widely implemented & understood
Since HOTA in 1999, 30 permanent SPECS1 projects
Since HOTA in 2009, 24 permanent SPECS3 projects with 14 SCPs
300+ projects have operated SPECS average speed enforcement
Operated with 20, 30, 40, 50, 60 and 70mph schemes

How speed management improves safety at works sites
Increased risks due to works
Use speed management to:
– reduce risk of collisions
– reduce severity of collisions
– reduce risk of intrusion into works area

Roadworks Enforcement
23 projects currently on the ground250 schemes have used SPECS average speed enforcementHighways Agency, Welsh Assembly & Transport Scotland use as standardOriginal justification was safety, along with:• smoother traffic flows• more reliable journey times• low offence levels• reduced emissions & noise
Consultative approach to assist designers
Solutions to improve roads, journeys and communities
Roadworks Experience – smoother flows
M8 j28, January – April 2007Identical works were carried out in 2006, using spot-speed camerasSignificant delays had occurred:• 10-15 minutes on M8 (morning
peak)Findings
No delays on M8 at morning peakTraffic volumes were greaterCompliance with the 40mph speed limit is 99.7%Average speeds are 38mph through the scheme

Safer >70% KSI Casualty reductions, typically
The casualty case is well proven: £1.6m (€1.9M) saving per site, per year
Data based on 3 year baseline and 3 year post-installation, extrapolated where less than three years installed.
Not isolated results75% reduction on average
Contentious for some!

Design Considerations
Hours of operation?Communications?Power?Visual appearance (columns, colour, signs)?Front or rear facing?Enforcement regime?• How many potential live links?• How many active live links?• Multiple offences on one journey?• Reporting on detection & offence levels?

How to protect a road works site
Reduce speeds on approach• ensure safe passage into TM
Maintain constant speed through works area• achieve harmonised speeds
Release back to normal speed limit at departure• and not before!
Comply always with your national regulations / guidelines• don‘t feed the campaigners – or the lawyers
Solutions to improve roads, journeys and communities
How to protect a road works site
Reduce speeds on approach
• place first camera:
• after change in speed limit
• before entry into the cones
• definitely before any lane narrowing or deflection
Solutions to improve roads, journeys and communities
How to protect a road works site
Maintain harmonised speeds
• Observer Effect: remind them they’re being monitored
• place a camera every 2 to 3 minutes’ driving time
• use clear signing, of limitand of enforcement system

How to protect a road works site
Maintain harmonised speeds
• Don’t leave gaps• regular drivers will learn where they pass cameras
• Cover slips where you can• extra camera?• change the layout to reduce gaps?
Solutions to improve roads, journeys and communities
Solutions to improve roads, journeys and communities
How to protect a road works site
Release drivers safely beyond works area
• place final camera past the end of the risk area
• make sure drivers can see a camera in front as they exit the cones

SummaryHarmonise speeds
• Reduce risk
Reduce speeds
• Reduce severity
Safer journeys & works
More reliable journeys
Reduced cost and impact
