Evaluation and Prediction of Drivers' Activities on the Basis of Congestion Consciousness

高速公路拥堵信息对驾驶员有很多好处，因为它不仅可以减少驾驶员的烦恼，而且可以为他们提供有价值的信息，以便在高速公路或高速公路上为自己选择最佳路线。另一方面，也有人批评目前高速公路信息所使用的定义与驾驶员的拥堵意识存在差异，本文通过对高速公路驾驶员拥堵意识的问卷调查，研究了两者之间的差异。提出了基于驾驶员意识的高速公路拥堵定义，并通过与真实的驾驶情景下驾驶员意识实验的对比，验证了该定义的合理性。此外，通过使用模糊推理改进了拥塞定义。

Information on freeway congestion has many advantages for drivers because it can not only decrease driver's irritation but also give them the valuable information in order to select the best route for themselves, on a highway or freeway. On the other hand, it is also criticized that the current definition used by freeway information has discrepancy to drivers' consciousness of congestion.We studied the discrepancy between them according to a questionaire of congestion consciousness of freeway drivers. And we proposeda definition of freeway congestion on the basis of drivers' consciousness.We also verified the propriety of this definition by comparing with the experiment on drivers' consciousness under the real driving situation. Furthermore the congestion definition is improved by using a fuzzy reasoning.
