改进的两车道交通流格子模型及扰动分析
, PP. 131-137
Keywords: 交通工程,流量转移率模型,数值模拟,两车道交通流格子模型,换道系数,换道阈值
Abstract:
为了了解两车道交通流的内在规律，更加真实的描述两车道交通流的换道情形，分析了现有交通流格子模型中存在的问题，通过引进换道系数和换道阈值，改进流量转移率模型获得了新的两车道交通流格子模型，克服了现有模型中存在的不合理现象。并利用VISSIM仿真确定换道阈值，然后再根据matlab编程对改进后两车道交通流格子模型进行了模拟分析，结果表明了改进模型的合理性与优越性，证实了改进模型在描述车辆换道的过程和趋势方面与实际更为相符。
