TL;DR: Results demonstrated that the general pattern of experimental results reported in the literature aligns well with the cognitive control hypothesis and that several apparent discrepancies between studies can be reconciled based on the proposed framework.
Abstract: Objective:The objective of this paper was to outline an explanatory framework for understanding effects of cognitive load on driving performance and to review the existing experimental literature in the light of this framework.Background:Although there is general consensus that taking the eyes off the forward roadway significantly impairs most aspects of driving, the effects of primarily cognitively loading tasks on driving performance are not well understood.Method:Based on existing models of driver attention, an explanatory framework was outlined. This framework can be summarized in terms of the cognitive control hypothesis: Cognitive load selectively impairs driving subtasks that rely on cognitive control but leaves automatic performance unaffected. An extensive literature review was conducted wherein existing results were reinterpreted based on the proposed framework.Results:It was demonstrated that the general pattern of experimental results reported in the literature aligns well with the cognitive c...

TL;DR: The Drive Me project as mentioned in this paper aims to put a fleet of 100 autonomous vehicles in the hands of ordinary Volvo customers to operate on public roads in Gothenburg, Sweden, in 2017.
Abstract: The Drive Me project focuses on studying potential benefits when autonomous vehicles are introduced on larger scale in the road transportation system. It aims to put a fleet of 100 autonomous vehicles in the hands of ordinary Volvo customers to operate on public roads in Gothenburg, Sweden, in 2017. The customers will not need to continuously supervise the vehicle operation and therefore will be allowed to spend time on other activities. The autonomous vehicles will be used as measurement probes for research on the effect on safety, traffic flow, and energy efficiency. Thus, the Drive Me project has a high-profile ambition to define and evaluate how autonomous vehicles will have a major importance for quality of life and achievement of a sustainable urban environment.

TL;DR: Although there are individual differences in head-eye correspondence while driving, head-rotation data may be a useful predictor of glance location, and future work needs to investigate the correspondence across a wider range of individuals, traffic conditions, secondary tasks, and areas of interest.
Abstract: The relationship between a driver’s glance pattern and corresponding head rotation is not clearly defined. Head rotation and eye glance data drawn from a study conducted by the Virginia Tech Transportation Institute in support of methods development for the Strategic Highway Research Program (SHRP 2) naturalistic driving study were assessed. The data were utilized as input to classifiers that predicted glance allocation to the road and the center stack. A predictive accuracy of 83% was achieved with Hidden Markov Models. Results suggest that although there are individual differences in head-eye correspondence while driving, head-rotation data may be a useful predictor of glance location. Future work needs to investigate the correspondence across a wider range of individuals, traffic conditions, secondary tasks, and areas of interest.
