White-on-blue logo signs are used to inform drivers of food, gas, lodging, and attraction businesses at highway interchanges. In this study, 60 drivers were asked to look for food and attraction targets on logo signs while driving in a realistic freeway simulation. The objective of the study was to quantify effects of the number of sign panels (six vs. nine), logo familiarity (familiar vs. unfamiliar), logo format (text vs. pictorial), and driver age (young, middle, and elderly) on performance, attention allocation and target identification accuracy. Results revealed elderly drivers to exhibit worse performance in comparison to middle-age and young groups even though they adopted a more conservative driving strategy. There was no significant effect of the number of panels, logo familiarity, and logo format on driver performance or attention allocation. In target identification, drivers were more accurate with familiar or text-based panels appearing in six-panel signs.
蓝底白字的标志用于在高速公路交汇处向司机告知食品、汽油、住宿和景点等商家信息。在本研究中，60名司机在逼真的高速公路模拟驾驶中被要求寻找标志上的食品和景点目标。该研究的目的是量化标志面板数量（六个与九个）、标志熟悉度（熟悉与不熟悉）、标志形式（文字与图片）以及司机年龄（年轻、中年和老年）对驾驶表现、注意力分配和目标识别准确性的影响。结果显示，尽管老年司机采取了更保守的驾驶策略，但与中年和年轻群体相比，他们的表现更差。面板数量、标志熟悉度和标志形式对司机表现或注意力分配没有显著影响。在目标识别方面，司机对出现在六面板标志中的熟悉或文字型面板的识别更准确。
