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.

    Impact of speed limits in Barcelona
    When Barcelona imposed an 80km/h (50mph), the result was significant in environmental, accident, fatality and injury terms. The 80km/h speed limit had the same positive environmental effect as if 22,100 cars were eliminated from the roads in the metropolitan area. Moreover, a reduction in the consumption of fuel by more than 24,000 tonnes per year was also achieved, while accidents, fatalities and injuries also showed substantial improvement.

    If you want to get up to speed on the main issues facing the transport sector and tolling companies, ASECAP Study Days event in Ljubljana was a good place to start. Colin Sowman reports (Photographs: Louis David). Increasing populations, ever-higher technical and safety requirements, and electric and hybrid vehicles will provide both challenges and opportunities for tolling companies. The annual Study Days event organised by ASECAP (the European association for tolling companies) examined all of these aspec

    Knowing when to slow down
    Level 2 driver assistance vehicles have little problem reading fixed metal signs at the roadside - but it’s a different story with VMS in tunnels, finds Alan Dron. Following a series of hands-free driving tests in tunnels, an Australian road authority believes that car manufacturers have to up their game before vehicles have the required levels of competence to consistently perform ‘assisted driving’ tasks. The trials, in the state of Victoria late last year, tested the ability of several vehicles to stay
