摘要
为分析多源出行信息对驾驶员认知负荷的影响机制,设计包含可变信息板(VMS)、交通广播以及这两者相结合的3种模拟驾驶场景,通过建立驾驶员认知负荷测评量表,采集驾驶仿真试验及认知负荷量表数据,测度多源信息影响下的驾驶员认知负荷。结果表明:3种场景中的出行信息均会影响驾驶员的认知负荷,单一VMS场景的认知负荷最低,多源信息场景最高;单一VMS场景中信息搜寻的认知负荷低于交通广播,获取和决策过程则高于交通广播;多源出行信息对认知负荷的影响维度主要是脑力负荷和时间负荷;出行经验对认知总负荷的影响与场景相互独立。
In order to analyze the mechanism by which multi-source travel information affects the driver＇s cognitive load,three driving scenarios were simulated,which included VMS（ variable message signs）,traffic broadcast,and combination of the two. A measurement table of driver ＇s cognitive load was established. Cognitive loads of drivers under the influence of multi-source travel information were assessed based on data from driving simulation experiment and the cognitive load measurement table. The results show travel information affects the driver＇s cognitive load in all three scenarios,that the cognitive load in a single VMS scenario is the lowest,and that in the multi-source information scenario is the highest,that the cognitive load of the travel information search process in a single VMS information scenario scene is lower than that in the traffic broadcast scenario,but that of reception and decision-making process is higher than that in the traffic broadcast scenario,that the dimensions on which the multi-source travel information has a great effect are the cognitive load is mental and time load,and that the travel experience and the scenarios affect independently of each other the total load.
