We have designed a new in-vehicle eco-safe driving system and shown its effectiveness in prompting drivers to execute a fuel-saving and safe driving style (Vaezipour et al., 2018, submitted for publication). However, the system could also bring potential negative outcomes, i.e. driver distraction. This simulator study investigated drivers' glance behaviours as indicators of driver distraction when using our Eco-Safe Human-Machine-Interface (HMI). Four types of eco-safe information display conditions (baseline, advice only, feedback only, both advice and feedback) were tested on different traffic situations with varied road traffic complexity. Results showed that the eco-safe HMI system did not cause visual distraction. In contrast, the advice only or feedback only information improved forward gazing on the roadway. In addition, drivers tended to adapt their visual scanning strategies according to the traffic situations. In the car-following situation they paid longer glances to the forward roadway, while in the intersections they spent more time to look at the HMI system. The findings indicated that our eco-safe driving system improved drivers' eco-safe behaviours and meanwhile enhanced their visual attention on road while no evidence showed that drivers were distracted by it.
我们设计了一种新的车载生态安全驾驶系统，并证明其在促使驾驶员采取节油和安全驾驶方式方面的有效性（Vaezipour 等人，2018 年，已提交出版）。然而，该系统也可能带来潜在的负面后果，即驾驶员分神。本模拟器研究调查了驾驶员在使用我们的生态安全人机界面（HMI）时的目光行为，以此作为驾驶员分神的指标。在不同的交通情况下，针对不同的道路交通复杂度，测试了四种生态安全信息显示条件（基线、仅提示、仅反馈、提示和反馈）。结果表明，生态安全 HMI 系统不会造成视觉分神。相反，仅提示或仅反馈信息会提高驾驶员对道路前方的注视。此外，驾驶员倾向于根据交通情况调整其视觉扫描策略。在跟车情况下，他们会将更多的时间用于注视前方道路，而在交叉口时，他们会将更多的时间用于查看 HMI 系统。研究结果表明，我们的生态安全驾驶系统改善了驾驶员的生态安全行为，同时增强了他们对道路的视觉注意力，没有证据表明驾驶员因此而分心。
