文章对引道延误和占有率分别进行了陈述，利用校验后的仿真模型，通过均匀设置在交叉口进口道的33个检测器，将进口道分为若干个小段，借助于检测器检测到的占有率和计算得到的车辆以自由行驶速度通过该检测段的时间，使用概念分析的方式推算车辆在每个断面的总延误，通过累加得到整个进口道的引道延误，结合每个周期的流量可以得到每周期的车均延误值。通过与仿真平台直接提取的延误值对比，得到延误估算的平均误差值为17.35％，即检测精度为82.65％，表明通过占有率推算进口道的延误具有较高的精度。

The meaning of the approach delay and time occupancy is described .Through the validated simulation model ,33 detectors are uniformly installed on the approach at the five meters interval and the approach road is divided into several segments by the detectors .Based on the detected time occu-pancy and calculated time that the vehicle passes the segment at the free speed ,using the concept a-nalysis ,the delay at this segment can be got and the approach delay be calculated by adding the each segment’s delay .The average vehicle delay can be calculated accordingly considering the traffic flow of the cycle .Comparing the calculated delay deduced in the paper and the true delay of the vehicle ob-tained by the simulation platform ,the mean error is 17.35% ,namely the precision of the method is 82.65% .It is proved that the proposed method has high delay parameter extracting precision .
