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.

The five-year contract to operate the routes has been awarded to Go Ahead following a competitive tender process, and will mean that 51 electric buses will operate across the two routes that will become the second and third pure electric bus routes in the Capital. Go Ahead will confirm which manufactu

    Cohda trial proves C-ITS can work in tunnels
    Connected cars require uninterrupted signals to ensure driving safety. Going underground creates problems – but a trial in Norway suggests that there might be light at the end of the tunnel… As connectivity becomes increasingly important for transportation – in particular for connected and autonomous vehicles (C/AVs) - the problem of ‘blackspots’ and dead zones where signals fail or drop out is a pressing one. But developments early this year suggest that advances in technology might be on the brink of d
