鉴于目前交通流领域中特殊路况引起道路通行能力下降的研究课题的匮乏,本文考虑到了行驶在坡道上的车辆不可避免要受到自身重力的影响,而提出了一改进的Nagel-Schreckenberg模型。计算机数值模拟结果显示,改进后的模型能准确反映特殊路段对行驶车辆的影响,同时再现了与实际交通相一致的时走时停交通波等复杂的非线性现象。
In view of the lack of research topics in the current traffic flow field, the Nagel-Schreckenberg model is proposed in this paper, taking into account the inevitable impact of vehicles on the ramp due to their own gravity. Computer numerical simulation results show that the improved model can accurately reflect the impact of special road sections on the traveling vehicle and at the same time reproduce the complicated non-linear phenomena such as time-lapse traffic wave which is consistent with the actual traffic.
