Project: On The Spot Accident Investigation Project Phase 3

Reference: S0603/V6

Last update: 26/04/2011 16:46:01


The objective of the study is to investigate accidents in order to provide:
1. a greater understanding of the contribution of human factors, vehicle design and environment in accident causation and injury outcome;
2. a greater understanding of injury mechanisms to road accident casualties and injury outcome;
3. support for legislation and other standards to reduce accidents and mitigate their effects through the provision of statistically valid data on accident causation and injury.


In 1999, the Department commissioned phase 1 of the 'On The Spot' (OTS) accident research project to collect data on all types of road accidents. Accidents were investigated in-depth to study the influences on accident causation and injury mechanisms of human involvement, vehicle design and highway design.

Phase II began in 2003 and continued to October 2006. Phase III continues to collect accident data and further improve the methodology. Increasing the number of cases in the database results in a more robust data set and ensures that new technologies continue to be represented.
The work is funded jointly by DfT's TTS Division, RUS and the Highways Agency
