考虑驾驶员在交通流中的胆怯或攻击行为，提出了一种改进的最优速度模型。通过线性稳定性分析，研究了喇叭声环境下驾驶员特性对交通流稳定性的影响。结果表明，与驾驶员特征相关的参数和喇叭效应对交通流的稳定性都有显著影响。确切地说，在鸣喇叭环境下，胆小驾驶员比激进驾驶员更有利于提高交通流的稳定性;在相同的鸣喇叭环境下，对于相同的驾驶员特征，技术越熟练的驾驶员更有利于提高交通流的稳定性。最后，许多仿真结果与理论研究结果一致，证实了驾驶员特性对交通流动力学起着重要的作用。
A modified optimal velocity model is proposed by considering the timid or aggressive characteristics of drivers behavior on traffic flow. The effect of driver’s characteristic on the stability of traffic flow under honk environment is examined through linear stability analysis. It is shown that the parameters related to driver’s characteristics and honk effect all have significant impact on the stability of traffic flow. Precisely, the timid driver is more beneficial to improve the stability of the traffic flow than the aggressive one under honk environment; moreover, the more skillful driver is more advantageous to improve the stability of traffic situation under the same honk environment for the same driver’s characteristics. Finally, many simulation results are found consistent with the theoretical findings which confirm that the drivers characteristics play a significant role on traffic flow dynamics.
