驾驶员对北京市道路交通标志的感知和理解

通过模拟在交通标志引导下到达指定地点的过程,研究了北京市道路交通标志信息量以及驾驶员脑力负荷对感知和理解道路交通标志的影响.在已有研究的基础上,改进了交通标志信息量的计算方法.相关分析结果表明,该方法很好地拟合了驾驶员对交通标志信息量的主观评价.方差分析结果表明:1)信息最的大小对驾驶员感知和理解交通标志没有显著影响;2)脑力负荷对交通标志识别率、决策时间、决策正确率以及决策确信程度有显著影响;3)脑力负荷对主观任务负荷和识别交通标志的时间没有显著影响.

A Driver's Perception and Comprehension of Traffic Signs in Beijing

A driver's ability of perceiving and comprehending traffic signs is affected by his/her mental workload and the information volume of the traffic signs.In this paper,a novel method is proposed to determine the information volume.By a simulation experiment for the process of driving to the destinations with the guide of traffic signs in Beijing,it is shown that the proposed method fits the subjective rating of the information volume well.Further analysis indicates that 1) the effect of the information volume...
