| 摘 要： | 为了解决过饱和状态下短连线的信号交叉口路段长度对延误影响的问题,推导出了基于短连线的过饱和信号交叉口最大延误模型。首先分析经典延误模型的盲区:在连接短连线信号交叉口车辆排队长度达到路段长度后,排队车辆就不能再增加;然后利用排队长度与延误关系推导出适用于该状态下的延误模型,并且提出当短连线相连2个交叉口信号相位差为0时所计算出来的延误是最大延误;最后通过算例对比了提出的延误模型与定数理论延误模型。结果表明:路段长度限制对于过饱和状态下连接短连线的信号交叉口延误的计算有很大影响,所提出的方法能够有效解决这一问题。 |

| Abstract: | In order to study the impact on delay in short length signalized intersection under supersaturated traffic flow,authors deduced a new maximum delay model under the condition.Firstly,the classic delay model didn't consider that no car could be in road when the length of queuing cars arrives at the length of road.Then,authors deduced the new delay model by using the relationship between the queue length and delay under the condition and presented that the delay was the longest delay when adjacent short length... |
