Effects of Cooperative Vehicle Infrastructure System on driver's attention with different personal attribute

This paper investigates the influence of Cooperative Vehicle Infrastructure System (CVIS) on driver's visual performance with different personal attributes (i.e., gender and driving experience). Taking the expressway work zone as an example, this research carries out a driving simulator experiment to compare driver's glance behaviors on forward roadway between cooperative vehicle (CV) and baseline (BL) conditions. The results indicate that CVIS applications change the driver's information processing mode on the forward roadway, with higher glance frequency and shorter average dwell time, and the overall time allocation on the forward roadway is also reduced. At the same time, male and female drivers adopt different visual processing strategies for the concentration on forward roadway, and CVIS strengthens the visual performance differences related to gender. The findings further show the necessity of personal attributes to be considered in the safety test of CVIS. The method proposed in this paper can be extended to the safety test of other application cases, and provide theoretical support for the customized design and optimization of CVIS information interaction.
