【摘要】 不合理的交通标志会削弱关键有效信息的效用,同时增加驾驶人的驾驶心理负荷,影响道路交通安全。本文从驾驶心理负荷的角度全面阐述了交通信息量度和道路交通安全的研究进展。首先分析和总结了道路交通标志信息对驾驶心理负荷的影响机理,现有研究表明交通标志信息量显著影响驾驶负荷,并可用模型描述;标志信息表现形式也影响驾驶负荷,但无有效模型表述。其次分析了国内外道路交通驾驶负荷的评价指标和实验方法,主要有主任务测量法、次级任务测量法、生理心理测试法、主观评价法等。最后对道路交通信息定量研究及其对驾驶负荷的影响进行了展望。更多还原

【Abstract】 Unreasonable and overmuch traffic sign information weakens the effectiveness of significant traffic information.It also increases drivers’ driving workload and influences traffic safety.In this paper,traffic sign information amount and road transport safety considering mental driving workload research progress are analyzed.Firstly,the mechanisms of mental driving workload caused by road traffic signs are analyzed.The previous researches indicate that traffic sign information amount significantly influences workload with clear model description,while traffic information expression form also influences driving workload without model.Evaluation and experimental methods for mental driving workload are also reviewed.The main evaluation methods are primary task method,index of the drivers’ physiological and psychological change factors,main driving performance evaluation,objective workload evaluation methods and reaction time.At last,the quantitative research of traffic information and its influence to driving workload are forecasted.更多还原
