Delivering the future of London’s traffic signals

Crossings with Pedestrian Countdown timers

Transport for London (TfL) has awarded new traffic signals maintenance contracts, worth around £317m for up to eight years, which will see the capital’s 6,000 traffic signals upgraded and maintained to the latest, greenest standards.

The Mayor and TfL are doubling the investment into London’s road network over the course of TfL’s business plan, from £2bn to £4bn.

The new Traffic Control Management Services contracts will help expand the use of intelligent traffic signals, as well as new crossings for pedestrian and cyclists, delivering benefits to all road users across London.

The new contracts will also deliver a substantial saving of around £42m compared to the previous contracts, achieved though competitive dialogue between the bidders and TfL.

This competitive dialogue allowed TfL and suppliers to remove many uncertainties from the contracts before they were signed, helping to ensure they used the most effective, energy efficient and best value equipment.

Doing so will allow London to remain at the cutting edge of traffic control technology.

Financial savings made through this contract will be shared between TfL and the boroughs to help accelerate delivery of further improvements to London’s roads.

During the timeframe of the contracts, TfL will carry out a range of works to improve traffic signals across London, including:

  • Rolling out a new ‘gold standard’ for all new and upgraded pedestrian crossings, which was launched recently as part of the Pedestrian Safety Action Plan. This will look to include Pedestrian Countdown timers to give pedestrians a clear indication of how much time they have to safely cross the road, as well as ensuring that all pedestrian crossing times take account of national safety standards and the level of pedestrian demand. TfL will also expand the use of Pedestrian Countdown across all 33 London boroughs in the coming years;
  • Continuing the roll-out of energy efficient Light Emitting Diode (LED) traffic lights across London to further reduce costs and associated emissions across London. Currently, 13 per cent of London’s traffic signals use LEDs and TfL is working to expand this to 100 per cent in the future;
  • Accelerating the installation of pedestrian and cycle improvement schemes, such as low level cycle signals, at key junctions across London. The contract will also see the completion of the roll-out of audible alerts or tactile rotating cones for visually impaired pedestrians at all pedestrian crossings by 2016.
  • Expanding the use of innovative Split Cycle Off-set Optimisation Technique (SCOOT) technology across London, which can change traffic signal timings based on traffic levels second by second, from half of all signals to three quarters of all signals by the end of 2018. On average, installing SCOOT at a junction reduces traffic disruption by between 8 and 12 per cent.

The new contracts will also deliver a range of benefits to London in addition to better traffic signals.

All vehicles working on the contracts will need to be Euro-5 compliant and signed up to the Fleet Operator Recognition Scheme, helping to reduce associated pollution and reduce the risk of collisions involving pedestrians and cyclists.

The contracts will ensure all employees are given at least the London Living Wage, create over 100 apprentice positions across London and encourage contractors to offer work placements to help ex-Armed Forces members – who may be wounded, injured or sick – back into employment.

Dana Skelley, Director of Asset Management at TfL, said:

‘London is world-leading when it comes to traffic signals management and these new contracts will allow us to continue this well into the future.

‘By entering into competitive dialogue with the bidders we have been able to deliver huge savings for London, which can be reinvested back into delivering further improvements for all road users.’

Subject to the ten day standstill period, the contracts will be awarded to:-

West London  –  Telent Technology Services Limited
North London – Siemens plc
North East London  – Siemens plc
South West London  – Telent Technology Services Limited
South East London –  Cubic Transportation Systems (ITMS) Limited
