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.

    IAM RoadSmart says it is unconvinced of value of the decision by City of Edinburgh Council to impose a 20mph speed limit on the vast majority of the capital’s streets as of 31 July. The multi-million pound scheme is the first of its kind in Scotland and will affect more than 80 per cent of the city’s roads. IAM RoadSmart, the UK’s independent road safety charity stated that the proposals amounted to a city-wide limit that didn’t address specific problematic roads. Neil Greig, IAM RoadSmart policy a

    Driverless cars could significantly reduce delays according to a new study by the Department for Transport (DfT). The project used computer software to create virtual models of different parts of the UK road network including urban roads and a 20km motorway section. Delays and traffic flow were all shown to improve as the proportion of automated vehicles increased above specific levels.
