Central London Congestion Charging Scheme

Client: Transport for London
Duration: August 2006 - February 2008

Project Overview
The Central London Congestion Charging Scheme (CLoCCS) went live on 17 February 2003. It was the first scheme of its type, and has been widely seen as a success, both in terms of the technology used, and the effect on congestion in central London.

In August 2004, the Mayor of London published a revision to the Transport Strategy, including proposals to extend the congestion charging zone to the west. The Western Extension Zone went live on time in February 2007, and is already delivering substantial benefits.

CPC’s Role
CPC consultants were engaged by TfL to undertake the Technical Design Evaluation phase, and subsequently the implementation phase of the Western Extension. CPC provided expertise in the evaluation, procurement and implementation of the Automatic Number Plate Recognition systems (ANPR) used to enforce the Western Extension.

CPC is able to provide the following services to Road Pricing clients:

• Technical project management
• System Integration services
• Programme management
• Technical consultancy in ANPR and DSRC systems
• Consultancy on Evidential Integrity matters
• Technical consultancy on system performance improvement
• Technical consultancy on system interoperability
• Technical consultancy on equipment environmental testing to Highways Agency and international standards
• Consultancy on streetscape and roadside planning matters
• Consultancy on Journey Time Monitoring Systems (JTMS), and impacts monitoring systems

Client Benefits
• TfL prides itself on being an informed client (see http://www.nao.org.uk/publications/nao_reports/06-07/060733-ii.pdf for recommendations from NAO). CPC contribute to this.
• TfL has deployed 1000 ANPR cameras in less than 12 months from contract let. This is around 1/3 the time of similar projects.
• CPCs contribution to measurement activities means that TfL was informed early on of system characteristics which are important to integration with existing systems.
