Bus driving is a complex and cognitively challenging task that places high demands on bus drivers’ working memory. Increasing use of “In-Vehicle Information Systems” leads to driver distraction and is a contributing factor to many road accidents globally, and with systems for tickets, navigation, and timetables, bus drivers are more exposed to this additional workload than other actors in the traffic. This study provides insights into how bus drivers’ driving behavior is affected by auditory traffic information through a driving simulator study at the Swedish National Road and Transport Research Institute. A pre-study showed that many bus drivers in Gothenburg experience that a majority of the messages they receive are irrelevant to them. Difference in driving behavior was identified for conditions in which the drivers received messages irrelevant to their route, which might indicate that irrelevancy is an important factor for the workload imposed to the drivers. We hypothesize that irrelevant messages require processing in the visuospatial sketchpad, which might increase workload more than just auditory information processing. The results of this study implies that the routines for traffic communication between traffic controllers and bus drivers should be considerate, as to reduce the number of irrelevant messages that are cognitively loading the bus drivers.

信息相关性对驾驶行为的影响

公交车驾驶是一项复杂且具有认知挑战性的任务，对公交车司机的工作记忆提出了很高的要求。越来越多地使用“车载信息系统”会导致驾驶员分心，并且是全球许多道路事故的一个促成因素，而且有了车票、导航和时间表系统，公交车司机比其他参与者更容易承受这种额外的工作量。交通。这项研究通过瑞典国家道路和运输研究所的驾驶模拟器研究，深入了解了公交车司机的驾驶行为如何受到听觉交通信息的影响。一项预先研究表明，哥德堡的许多公交车司机都认为，他们收到的大部分信息都与他们无关。在驾驶员收到与其路线无关的消息的情况下，确定了驾驶行为的差异，这可能表明无关性是施加给驾驶员的工作量的重要因素。我们假设不相关的消息需要在视觉空间画板中进行处理，这可能会增加工作量，而不仅仅是听觉信息处理。这项研究的结果表明，交通管制员和公交车司机之间的交通通信例程应该考虑周到，以减少对公交车司机造成认知负担的不相关消息的数量。这可能会增加工作量，而不仅仅是听觉信息处理。这项研究的结果表明，交通管制员和公交车司机之间的交通通信例程应该考虑周到，以减少对公交车司机造成认知负担的不相关消息的数量。这可能会增加工作量，而不仅仅是听觉信息处理。这项研究的结果表明，交通管制员和公交车司机之间的交通通信例程应该考虑周到，以减少对公交车司机造成认知负担的不相关消息的数量。
