Safety is at the heart of Transport for London’s bus operations. The Mayor of London has made clear that loss of life and serious injuries on London’s roads are neither acceptable nor inevitable and Transport for London’s has now adopted Vision Zero for London, with a target of zero deaths or serious injuries by 2041. For buses, Transport for London have an even more ambitious target of no one killed in, or by, a London bus by 2030.

To achieve this, Transport for London’s strategy is to develop new safety features on buses. In February 2016 a bus safety programme was launched, including a commitment to develop a ‘Bus Safety Standard’, to ensure that the safest buses are driven on London’s roads.

TRL was commissioned to research and develop that standard. This has been an evidence-based and collaborative project, consulting with the bus manufacturers and operators on technical feasibility, timelines and implementation so that everyone has the confidence that the safety measures will make a real contribution to Vision Zero.

The Bus Safety Standard will provide a substantial proportion of the casualty savings required to meet the targets, and this document summarises the safety measures featured. Not all the technologies are available immediately and some will require development time, so Transport for London’s bus safety roadmap sets out future plans for the buses, to give the manufacturers time to invest in these new safety features. The standard will continue to evolve to take account of technology innovations in the future.

The Bus Safety Standard has been developed by Transport for London, for London, but the benefits are potentially global.

The Bus Safety Standard now comprises a suite of 14 documents listed here: the Executive Summary, a Roadmap, and then 12 reports evaluating different safety measures.
