Recent reports from the city of Oslo, where there was only one road traffic death in 2019, have highlighted the impact of traffic reduction on road danger. What assessments and data does Transport for London (TfL) have concerning the relationship between traffic volumes and road danger?

I am very encouraged to hear of the remarkable success of the city of Oslo in reducing the number of road traffic deaths to only one in 2019. Though Oslo’s population is far smaller than London’s, it shows that an approach incorporating traffic reduction measures can lead to a significant reduction in the number of people killed on a city’s roads. My own Vision Zero action plan ( recognises the importance of this relationship and states that “reducing the dominance and overall numbers of the most dangerous vehicles is central to the Healthy Streets Approach and to achieving Vision Zero, and will reduce Londoners’ exposure to road danger.”

Transport for London’s current research commission to develop a measure for road danger is exploring in more detail the relationship between traffic numbers and road danger. This work will complete in February 2020 and will be used to identify and prioritise high-risk locations for safety engineering.
