This study analysed 197 police fatal files where a pedestrian was killed in London in the period 2006–2010, with the overall aim of providing a better understanding of how fatal pedestrian collisions in London could be prevented. The files were broadly representative of fatal pedestrian collisions in London over the period.
The fatal files were coded into a database based on Haddon’s Matrix, which included items related to the environment, the pedestrian, vehicle(s) and their driver(s)/rider(s) in terms of pre-event, event and post-event.
The project identified the factors or primary interventions, which if they had been in place may have prevented the collision occurring (primary prevention). Further, the project considered the causes of the injuries and where practical identified the secondary interventions, which if they had been in place may have reduced their severity.
Several groups of fatalities were identified as being of special interest because of particular characteristics of the collisions. These groups generally accounted for a substantial proportion of the fatalities. In each case, the collisions within each group were analysed in terms of who was involved, the contributory factors, injuries and possible countermeasures.
