Abstract

Abstract To clarify the effect of the cooperative vehicle infrastructure system (CVIS) application on drivers’ visual performance, a total of 37 drivers were recruited to drive the simulated roadway in a freeway work zone under baseline and cooperative vehicle environments. Drivers’ attention and concentration on the forward roadway, attention distraction, and attention distribution in both scenarios were analyzed. The results indicated that the CVIS application changed drivers’ information-processing mode in the forward roadway as manifested by higher glance frequency and shorter average dwell time. In addition, more off-road distractions were observed in the range of 500 m in front of the work zone, but focusing on human–machine interfaces (HMIs) was not the main cause. In conclusion, the change in the driver’s attention allocation and the diversion was clarified with the proposed visual link diagram. This paper provides a comprehensive approach to visual assessment of CVIS and contributes to the customized design and optimization of future CVIS-HMI.
协同车辆基础设施系统对驾驶员注意力的影响——基于工作区的仿真研究
摘要为研究协同车辆基础设施系统(CVIS)应用对驾驶员视觉性能的影响,在基线和协同车辆环境下,选取了37名驾驶员在高速公路工作区内的模拟道路上行驶。分析了两种情况下驾驶员在前方道路上的注意力和集中程度、注意力分散和注意力分配情况。结果表明,CVIS应用改变了驾驶员在正向道路上的信息处理方式,表现为更高的注视频率和更短的平均停留时间。此外,在工作区域前500 m范围内,注意力集中在人机界面(hmi)上并不是主要原因。综上所述,本文通过可视化链接图阐明了驾驶员注意分配和转移的变化。本文提供了一种全面的CVIS可视化评估方法,有助于未来CVIS- hmi的个性化设计和优化。
