Workpackage 1

  • Five pilot studies have been conducted to assess participants' performance on a number of tasks requiring visual attention, vigilance and memory.
  • Task difficulty was manipulated by increasing the number of items processed.
  • Baseline results will be used to assess the effect of tasks requiring different levels of perceptual and cognitive demand on driving performance.

Workpackage 2

  • The experiments were designed to evaluate the interaction between secondary tasks and driving.
  • Two 'surrogate-IVIS' tasks were developed: One task was designed to apply a systematic visual load ('Arrows'), while the other examined the effect of a systematic non-visual cognitive load on driving (auditory Continuous Memory Task).
  • The two surrogate IVIS tasks were tested across different road types, using a range of driving simulators and instrumented vehicles.

    Workpackage 3

  • The objective of this WP was to apply the methods used in WP2 to a number of 'real' systems in order to recommend a test regime for the safety assessment of IVIS
  • To examine the utility of recognised checklists as part of the test regime, the TRL checklist was used to evaluate the selected systems.
  • The scenarios and measures used in this WP were based on the findings from WP2. For instance, following a meta-analysis of the WP2 results, it was possible to draw conclusions about the types of road environment and behavioural measure that were most sensitive to changes in workload.
