Successful trials ‘prove effectiveness’ of speed limiting technology on buses

Transport for London (TfL) has completed trials of intelligent speed assistance (ISA) technology fitted to buses. The trials saw the technology, which prevents vehicles from accelerating over speed limits, fully tested on two bus routes that included a variety of road environments and differing speed limits. All buses fitted with ISA remained within the speed limit 97-99 per cent of the time, which TfL says proves the effectiveness of ISA. The extremely rare incidents of excess speeds were seen on downhi

1466 Transport for London (TfL) has completed trials of intelligent speed assistance (ISA) technology fitted to buses. The trials saw the technology, which prevents vehicles from accelerating over speed limits, fully tested on two bus routes that included a variety of road environments and differing speed limits.

All buses fitted with ISA remained within the speed limit 97-99 per cent of the time, which TfL says proves the effectiveness of ISA. The extremely rare incidents of excess speeds were seen on downhill sections of road.

TfL says the trials were particularly effective when travelling through 20mph zones, which are being widely introduced and cover around a quarter of London’s roads, helping to ensure other vehicles in the area adhered to the limit.

As part of the Mayor’s bus safety standard for London, that he announced last month, TfL intends to require all new buses from 2017 to have this technology fitted.

    T-Charge introduced to older vehicles in London to tackle toxic air pollution
    To combat thousands of premature deaths caused by air pollution in London, up to 34, 000 polluting vehicles travelling into Central London every month may have to pay the T-Charge £10.00 ($13.00) which will operate on top of the Congestion Charge £11.50 ($15.00). Launched by the Mayor of London Sadiq Khan, the T -Charge applies to drivers of pre-Euro 4 vehicles that do not meet the PM and NOx emissions and has come into effect from 7.00am on 23 October 2017.

    Real-time traffic updates to be displayed on London buses
    The iconic London bus is now helping to improve traffic in the Capital as Transport for London (TfL) starts a trial of displaying live traffic information on the back of buses. A number of buses on route 344 are displaying real-time traffic information using digital information boards in what is said to be a world first. The technology is being trialled on buses between Clapham Junction and Liverpool Street to provide London's drivers with a new source of information to help avoid congestion and improve

    New services and equipment helps cities tackle air quality issues
    With poor urban air quality shortening lives and fines being imposed for breaching pollution limits, authorities are seeking ways to clean up their cities. Poor air quality is topping the agenda for city authorities across the globe. In the UK, for example, a report from the Royal Colleges of Physicians and of Paediatrics and Child Health, concluded that poor outdoor air quality shortens the lives of around 40,000 people a year – principally by undermining the health of people with heart and/or lung prob

    Study looks at air quality impacts of low carbon buses
    A new report prepared by Ricardo for the Low Carbon Vehicle Partnership (LowCVP) to review the air quality impacts arising from the recent rapid increase in the number of low carbon buses in the UK recommends that the legislation needs to consider hybrid technology impacts in the test processes to avoid potential unintended consequences in terms of local emissions. As they mainly operate in urban areas, local emissions from buses are of particular significance. Reviewing worldwide test processes for
