How to analyse accident causation?

This handbook is designed to offer road safety professionals a detailed and practical overview of the various road safety diagnostic techniques available for studying road users’ behaviour during interactions, near-misses and accidents. It describes various road safety methods that can be applied for studying the safety of vulnerable (and other) road users, including: accident data analysis, conflict and behavioural observations, self-reporting and naturalistic studies and road safety audit and inspection. The handbook also focuses on delivering better calculations of the socioeconomic costs of vulnerable road user accidents. The authors discuss when those techniques function best, when they are not entirely suitable, and how they can bene it each other when used in conjunction. Applying the principles described in this handbook will contribute to the further improvement of road safety and a better, in-depth understanding of the causal factors contributing to vulnerable road user unsafety.
