Around 700 new buses are now fitted with Intelligent Speed Assistance (ISA). As this represents a relatively small part of the 9,000-strong fleet, Transport for London (TfL) has conducted monitoring where concerns have been raised over bus speeds in specific locations. Given up to 8,000 buses can operate at peak times, TfL is developing a more efficient and targeted way of monitoring speed compliance using existing bus technology, and plans to introduce this later this year.

From the end of 2019, new buses will additionally need to meet the Bus Safety Standard – a revised specification including new safety technology and enhanced design. This will incorporate ISA as a mandatory element so that a rising proportion of the fleet has it as a standard feature.
