以感知关系和反应时为表征的驾驶员感知不确定性在影响跟驰行为中起着关键作用，但相关文献研究较少。基于量子光流理论，提出了一个动态随机的驾驶员感知模型，研究了车辆跟驰过程中驾驶员感知相对速度的不确定性与反应时间的不确定性之间的关系.具体而言，该模型假设驾驶员感知速度和反应时间是时变的和不确定的，并在模仿海森堡不确定性原理的形式的权衡关系相关。为了验证这一论断，即在感知相对速度和反应时间的不确定性的权衡关系存在于汽车跟随，本研究进行定性分析，其次是两个阶段的实验植根于量子光流理论，使用从驾驶员模拟器收集的数据。分析结果进一步阐明了驾驶员感知不确定性下的跟车现象，可能有助于新的交通流理论的发展。(C)2015爱思唯尔有限公司版权所有。
Driver perception uncertainty characterized in perceived relatnd reaction time plays a key role in influencing car-following behavior; and however, is rarely investigated in related literature. Grounded on quantum optical flow theory, we propose a dynamic and stochastic driver perception model to investigate the relationship between the uncertainty of perceived relative speed and that of reaction time during car following. Specifically, the proposed model hypothesizes that driver perceived speed and reaction time are time-varying and uncertain, and correlate in a trade-off relationship mimicking the form of Heisenberg Uncertainty Principle. To test the assertion that a trade-off relationship of uncertainty in perceived relative speed and reaction time exists in car following, this study conducts qualitative analysis followed by a two-stage experiment rooted in quantum optical flow theory using data collected from a driver simulator. Analytical results further elucidate car-following phenomena under driver-perception uncertainty, potentially facilitating the development of new traffic flow theories. (C) 2015 Elsevier Ltd.
