Abstract
This paper presents the first results of a comparative evaluation of the behavioural effects of Collision Avoidance or Warning Systems. Three different systems were evaluated which differed in terms of the criteria used and their man-machine interfacing. The systems were implemented in a driving simulator and tested using critical vehicle interactions. Preliminary analysis concentrated on (1) time headways, which increased while driving with CAS operated by an active gas pedal and decreased while driving with autonomous intelligent cruise control, (2) subjective workload, which increased while driving with CAS operated by an active gas pedal and decreased while driving with autonomous intelligent cruise control, and (3) driver acceptance of CAS, which decreased while driving with CAS operated by an active gas pedal and with autonomous intelligent cruise control. (A) For the covering abstract see IRRD 868006.

The behavioural validation of driving simulators as research tools : a case study based on the Leeds Driving Simulator

TL;DR: The objectives of this thesis was to provide researchers with a scientitically-based guide for interpreting driver behaviour results obtained on a fixed-base driving simulator and to provide guidance on how the Leeds Advanced Driving Simulator (LADS) could be modified to overcome any deficiencies that were detected.
