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. However. objectives of any simulator validation study are directly related to the specitic driving task under investigation. our ability to perform a similar task in the field (for the comparison of the results between the two environments) and the existing configuration capabilities of the simulator. To achieve the objectives of this study, driver behaviour was investigated at the control level under different road geometry and oncoming traffic conditions using the LADS. Speed and lateral displacement in terms of mean and standard deviation were chosen to represent driver behaviour. They were measured under free-flowing conditions on a rural A road. The objectives of the study were fulfilled by comparing observational uncontrolled real road data with experimental simulator data and by evaluating the differences between the two environments using the absolute and relative validity criteria. It was found that LADS is relatively valid in terms of speed and lateral position. It was also found that higher speeds are developed in the simulator where speed in not confined by the road geometry and simulator subjects drive significantly closer to the edge of the road compared to their real road counterparts irrespective of the road geometry and the oncoming traffic conditions. The face validity of the simulator was examined using subjective data obtained from questionnaires relative to the realism and ease of controlling the simulator. Subjects commented that the least realistic features of the simulator were the braking and steering systems. Subjects were classiffied to "good" and "poor" according to their responses regarding the simulator face validity. It was found that "good" subjects behave slightly better compared to "poor" subjects when driving the simulator.
