| 摘 要： | 定义超车换道流量与干道流量的比值为超车换道率．通过对混合交通流动力学模型的特征关系式进行积分，得到了混合交通流参数之间的函数关系．分析流量、密度和超车换道率之间函数的极值，确定了混合交通流中超车换道率的变化范围．当超车换道率为0时，道路通行能力最大；超车换道率为-1时，道路通行能力最小．采用实测数据对混合交通流参数之间的关系进行了验证．结果表明两者符合较好．

| Abstract: | The ratio of overtaking flow to mainline flow was defined as the overtaking rate. After the characteristic relations of the dynamic model had been integrated, the relationships of the mixed traffic flow wer founded. Analyzing the extremum of the relationship of the overtaking of the overtaking rate and the speed, density and flow in the mainlines, the variety scope of the overtaking rate was determined. When the overtaking rate is 0, the road capacity is at the maximum; while the rate is -1, the capacity is at the minimum. The surveyed dates were adopted to test the relationships. The results indicate that the relationships would coincide with the data. |
