Lancashire tops the list of the highest number of pedestrians KSIs in road collisions, with over 150 in 2021, followed by Birmingham, Kent, Leeds and Essex, which all saw over 100.

In London, Westminster had the highest number of pedal cyclist and pedestrian KSIs. While Croydon saw a high number of pedestrians killed or seriously injured in collisions, places like Wandsworth, Southwark and Richmond saw higher numbers of cyclists KSI incidents.

London boroughs have seen huge changes to their road casualties over the past two years, caused by the pandemic.

Westminster saw the number of pedestrian KSIs in road collisions plummet during lockdown, from 102 in 2019 to 49 in 2020. In 2021, that number increased but is still 36% below the 2019 level.

Meanwhile, outer London boroughs like Croydon and Bromley have seen the number of pedestrian KSIs bounce back past the 2019 level.
