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.

Since last autumn, ten specially adapted Volvo trucks have been operating on Swedish roads using the fuel which reduces carbon emissions by 95 per cent compared with conventional diesel. The field tests have now reached the halfway point and the results so far have both met, and exceeded, expectations.
