LTCC London Traffic Control Centre, TfL 2004


Transport for London (TfL) ‘Keeps London Moving’ by influencing the way people and goods move around the capital’s roads.

Traffic congestion is minimised through real-time traffic management and ensures the network is optimised to safely balance the needs of all road users including freight operators, motorists, bus passengers, cyclists and pedestrians. And together with modern traffic infrastructure, technology and systems, London’s transport and traffic management services are continually enhanced to benefit the public and the economy.

In 2003 wpa Director Tylaar Haran was approached to redesign the The London Traffic Control Centre (LTCC).

The LTCC :-
• Coordinates the largest dynamic network management system in the world
• Refines traffic signal timings at 6,000 sites
• Actively manages the impact of incidents, with the Metropolitan Police Service
(1000 per month)
• Proactively manages traffic for major events in London with event sponsors and Metropolitan Police Service (40 per month)
• Enables the comprehensive network of bus priority at traffic signals
• Informs travellers of real-time and forecasted network disruption and congestion
• Improve safety at junctions and pedestrian crossings
• Supports TfL services, including public transport, freight, road user charging, walking, cycling, road safety and accessibility
• Supports London’s boroughs in the management, deployment and development of London’s traffic control infrastructure.


The LTCC watches over London’s busiest roads to reduce congestion 24 hours a day, 7 days a week. It is unique among the world’s traffic control centres as it carries out both real-time traffic management, and provides up-to-date traffic information. The LTCC’s team of traffic controllers monitor London’s roads, detecting congestion and potential problems as they develop, and co-ordinate responses. The LTCC also proactively plans and coordinates integrated responses to planned events with the potential to cause disruption to traffic movement. Examples include annual events such as the Notting Hill Carnival and Chinese New Year as well as special events such as Live8 and the Tour of Britain cycle race.

The LTCC Design Objectives were to:

  • Develop an LTCC layout to provide a more efficient and integrated work area.
  • Allow for the amalgamation of Area Traffic Controllers with the Area Traffic Teams
  • Provide a large video wall for monitoring real time events and emergencies.
  • Find an effective arrangement to allow for 5 Area teams to be positioned in such a way as to allow co-ordination with 3 ATC Controllers and to prevent distractive lines of sight.
  • Create an upper mezzanine area, to allow positions for a Supervisor with traffic up-date positions and Information Desk positions.
  • Create a Viewing Gallery to be maintained as open space with all the viewing positions glazed in.
  • Create an Incident Room viewing into the Traffic Control Area.
  • Allow for Secondary functionality: the Expansion Area & Viewing Gallery are to be set up as temporary operations areas for up to 26 positions.

wpa completed the project on time and to budget within a very challenging programme to meet tough Mayoral deadlines.
