摘要：研究驾驶人交通标志信息记忆量随时间的变化规律，能够为城市道路交通标志设计及实施应用提供有力支撑。在分析短时记忆时间规律、交通标志信息传输及度量的基础上，以一条有交通信息标志的实验路段为例，采用实验车调查法，结合心理学记忆理论，分析交通标志信息量对驾驶人短时记忆的影响，探究交通标志信息记忆量随时间变化的规律。结果表明，驾驶人对交通标志信息的短时记忆衰减规律符合艾定浩斯遗忘曲线。

Abstract：To reveal the pattern the amount of drivers' memory of traffic sign information changes over time could shed bright light on the design and installation of urban road traffic signs. Based on an analysis of short memory over time patterns, and the conveyance and its measuring of traffic sign information, this paper conducts, with the psychological theory of memory in mind, a test-car survey along a road segment installed with traffic signs, and investigates how the amount of traffic sign information impacts drivers' short memory, and how it changes over time. One of the findings shows that the Hermann Ebbinghaus Forgetting Curve is a good fit of the pattern that drivers' short memory of traffic sign information fades over time.
