中文摘要：

依据摄像头监控环境下可以检测到的相关参数,给出了信号控制交叉口进口道的车均控制延误参数提取的方法.文中以各个周期饱和度不超过1.2的信号控制交叉口进口道为研究对象,根据该周期的车辆通行需求和交通供给,将交叉口进口道的状态划分为正常交通状态和饱和交通状态;然后根据本周期车辆的到达情况、上周期排队车辆对本周期的影响及本周期排队车辆对下个周期的影响,结合监控环境下可以直接获取的相关参数,对两种交通状态分4种情况分析了交叉口进口道的控制延误参数的提取方法,构建了相应的模型.最后通过实例表明,该论文陈述的模型可以较好的提取交叉口进口道的控制延误参数.

英文摘要：

Using the directly detected data under the monitor environment,the signalized intersection control delay was described.The paper studying approach saturation was no more than 1.2.Firstly,the approach statues could be divided into normal statues and over-saturation statues according to the approachtraffic demand and supply.Then,the 4 cycles divided from the normal statues and over-saturation was analyzed considering the factors that the vehicles arrival at this cycle,the impact from the previous cycle and impact on the next cycle.Based on the analyzing,the control delay extraction model was made.Lastly,an example was given and the results improved that the model could get the approach control delay.The models described in this paper gave a method that the control delay under the monitor environment can be made.
