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 Mayor of London, Boris Johnson, has set out final plans for the construction of Europe’s longest substantially-segregated urban cycleways, the centrepiece of his US$1.3 billion commitment to get more Londoners on their bikes. Subject to approval by Transport for London, construction of the routes will begin in March. Two continuous cycle routes, almost completely separated from traffic, will cross central London from east to west and north to south, opening up thousands of new journey opportunit

    Intelligent intersection control systems have a growing role to play in making urban traffic more efficient. Robin Meczes reports. The idea of every traffic light turning green as you approach it has long been a dream for many an urban driver – and none more so than those driving heavy goods vehicles (HGVs), which are slow and difficult to bring to a halt and then accelerate back to normal travel speed. But that dream has become a reality for some drivers in a small number of cities around Europe in the las

    Wrong-way warning systems and advanced queue detection can help to reduce human error. They can also cut road accidents – and therefore road deaths, says Clearview Intelligence Where were nearly 1,800 deaths on the UK’s roads in 2018 – an average of five people dying each day. The largest single cause of serious injury is crashes at junctions (accounting for 33% of incidents), while the largest single cause of death was run-off road crashes (30%) “With vehicles increasingly being designed with saf
