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.

    Caldecott Tunnel’s new Fourth Bore is utilising a bespoke high-capacity monitoring and communications network from Moxa. The Caldecott Tunnel connects Contra Costa and Alameda counties in Northern California and traditionally it has suffered severe congestion - especially during peak hours. Opened in 1937 as a twin-bore arrangement, by 1964 the increase in traffic volumes led to a third bore being added. Shortly after the third bore was opened a tidal flow was introduced with the centre bore alternating in

The more strident proponents of newer and emergent detection technologies are quick to highlight what they see as the disadvantages, and hence the imminent passing, of the humble inductive loop. The more prosaic will acknowledge that loops continue to have a part to play in traffic management, falling back on the assertion that it is all a question of application. And yet year after year the loop, despite
