Road collision investigations: A field trial of a Self-Administered Interview designed for Road Traffic Collisions

The presentation will discuss work on a field trial of a revised version of the Self-Administered Interview for Road Traffic Collisions (the SAI-RTC), a new tool that allows witnesses to road traffic collisions (RTCs) to produce detailed and comprehensive accounts of the collision.

Over a 20-month trial period, officers within the Roads Policing Unit of a Welsh police force were trained to use the SAI-RTC, or they continued to collect witnesses using a standard reporting form. Researchers compared the outcomes of cases in the two arms of the trial, and also compared the quantity and quality of information that witnesses provided in the SAI-RTC, and in the standard reporting form.

This presentation describes the methods and key findings from the trial, which was generously funded by the Road Safety Trust.
