Why do people die in road crashes?

The Ministry of Transport has engaged TERNZ to analyse a sample of fatal crashes in detail to enable it to get a better understanding of why people die in crashes. The focus is not on the driver or other road use behaviours that initiate an incident but rather on why there was an impact severe enough to result in death. Factors of interest include: 1. the characteristics of the roadside, including any objects struck, lack of barriers etc.; 2. pre-crash speeds (related to impact severity rather than crash cause); 3. restraint or helmet use; 4. vehicle characteristics in terms of crash avoidance technology and aggressivity (how much damage a vehicle does to unprotected road users or other vehicles); 5. after crash medical care including the time delay between the trauma and medical intervention The specifications for the study required us to evaluate 120 crashes consisting of 70 open road crashes and 30 urban crashes involving trucks and/or cars and 20 crashes involving motorcycles. Crashes involving pedestrians and cyclists were excluded at this stage.
