Analysis of replacing conventional rear-view mirrors with camera-based systems in urban buses: an experimental study in real driving conditions
通过真实驾驶实验，比较城市公交车使用传统后视镜与两种摄像头系统（仪表盘和A柱显示屏）对驾驶员眼动行为、接受度和心理负荷的影响，发现A柱显示屏与传统后视镜差异不显著，但仪表盘显示屏表现更差。
The use of new instrumentation in vehicles is allowing the introduction of systems such as camera-based mirrors. However, in some types of vehicles such as urban buses, there is limited evidence of their impact on real-life conditions. This research presents an experimental study of buses operating both a route with passengers and another in a controlled scenario. Conventional mirrors are compared with two configurations of camara-based systems (displays mounted on the dashboard and on the front pillars). Eye-tracking behaviour is recorded and self-reported measures of acceptance (usability, usefulness, satisfaction, perceived safety, use preference), and mental effort are collected. The results show that differences between conventional mirrors and displays placed on the pillars are not statistically significant in basic eye patterns, but worse behaviour is detected in case of dashboard displays. These results may be useful for transport operators, technology manufacturers, and policymakers in the urban public transport sector.
