Speed limiters for London buses

All new buses on TfL routes from 2017 will now be required to have speed limiting technology fitted following a successful trial. According to the transport authority, the test of the Intelligent Speed Assistance (ISA) technology from Zeta Automotive proved it can be used to control speeds on London’s bus network. The equipment prevents vehicles from accelerating over speed limits. It was trialled on two bus routes that included a variety of road environments and differing speed limits. All buses fitted with it remained within the speed limit 97% to 99% of the time. The ‘extremely rare’ incidents of excess speeds were seen on downhill sections of road, say TfL. The trials were ‘particularly effective’ when travelling through 20mph zones.

MD of Surface Transport at TfL, Leon Daniels, said, ‘We’re investigating a range of new technologies that can make our bus network the safest in the world. These trials have proven that speed limiting technology can contribute to safer roads and streets. We’ll now work with manufacturers so that all buses coming off the production line can be fitted with the technology from next year.’
