摘要

为了评估车速反馈标志的实际效用,运用眼动仪和无线生理传感器进行实验并采集数据,从视觉特性、心电特性与皮电特性的角度分析驾驶人的生理心理变化规律,进而结合驾驶人行为特征评价车速反馈标志在城市道路上的适用性。实验结果表明:车速反馈标志使驾驶人的视觉负荷增加,信息搜索效率提高,视认轨迹清晰,关注度更高;车速反馈标志促使驾驶人交感神经系统活跃,伴随产生较高的心理负荷与紧张情绪,缩短了制动反应时间;车速反馈标志对驾驶人的跟随状态和制动状态均产生积极影响,能有效降低路段车速,达到提高道路安全性的目的。

Abstract

In order to evaluate the actual utility of speed feedback sign, eye trackers and wireless physiological sensors were used to carry out experimental investigations and data collection. The physiological and psychological changes of drivers were analyzed from perspectives of visual characteristics, electrocardiographic characteristics and electrical skin characteristics. Combined with the characteristics of driver behavior, the applicability of speed feedback signs on urban roads was evaluated. The experimental results showed that: the speed feedback sign could increase drivers′ visual load, improve the information search efficiency, the visual recognition trajectory was clear, and the attention was higher; the speed feedback sign promoted drivers′ sympathetic nervous system to be active, accompanied with higher psychological load and tension emotions, the braking reaction time was shortened; the speed feedback sign had a positive impact on drivers′ following state and braking state, which could effectively reduce the driving speed and improve the traffic safety.
