This report gives an overview of Phase 1 of the Road Accident In-Depth Studies (RAIDS) programme. The project was commissioned by the UK’s Department for Transport (DfT) and road collision data were collected by Loughborough University and TRL (the UK’s Transport Research Laboratory). TRL was responsible for the Programme and Technical management, including provision of an on-line database. The aim of the Road Accident In-Depth Studies (RAIDS) programme is to provide detailed evidence on the causes and consequences of road collisions in order to improve road safety outcomes. In phase 1, over 1,250 in-depth accident investigations were carried out to study the influence on crash causation and injury mechanisms of human involvement, road and environment design and vehicle safety. This ambitious work was undertaken to allow research to be conducted to investigate the causes of crashes, their subsequent injuries and the associated societal costs. It was recognised that only through a detailed knowledge of these complex causal factors will effective policies and countermeasures be developed and, ultimately, successfully applied to improve road transport safety. This report describes the data collection methodology and provides examples of some potential research applications. This is not intended to be a comprehensive review of all the RAIDS research opportunities; rather it is designed to offer an insight into the richness and diversity of the dataset. The report initially provides an overview of the Phase 1 data gathered. Secondly, some key findings from the first phase are presented to demonstrate the utility of the data, including: * Road user behaviour and collision causation; * Road design; * Car user injury experience; * Characteristics of pedestrian collisions; and * Vehicle technologies and collision injury prevention. From 1st April 2016, Phase 2 of the RAIDS programme started and will continue to collect data to add to the evidence base. The second phase will deliver a greater focus on advanced vehicle safety technologies and will help to assess the road safety priorities for tomorrow’s roads. (Author/publisher)
