摘要
提出基于车头时距分布的合流区段长度计算模型,并对合流模型中的车头时距分布公式的选用以及司机可接受的安全插车间隙进行了讨论和分析,并根据不同的司机可接受的安全插车间隙设计出了不同的合流模型验证方案,用以验证合流模型的实用性。结果表明,插车间隙为3s时,道路的通行能力、司乘人员舒适度、车流、加速度以及车流稳态等方面均能达到最优。
This paper puts forward vehicle merging model based on vehicle head interval distribution and discusses the equations for head interval distribution,the acceptable safe merging headway is also included.Different experimenral schemes in different driver acceptable safe merging headways are designed to testify the merging model.It is concluded that the road capacity, traveling comfort, vehicle acceleration and flow stability are satisfied when the headway is 3 s.
