中文摘要
      本文阐述了离散时间点过程理论，时变马尔科夫链及鞅差分序列在城市交通车队状态观测器中的应用。并在此基础上，改进了[5]中的估计算法。用本文提出的非线性最小方差估计算法，对[5]提供的交通状态进行估计，所得记过比[5]中算法精度有明显提高。在大连市某交通干线计算机控制系统中初步应用，取得了令人满意的结果。
英文摘要
      This paper presents some applications of discrete-time point process theory, time-varying Markov chain and Martingle difference in urban traffic computer-based control systems. On this basis We established a new queue model. The new algorithm we proposed to predicte the state of queue in the model was tested in comparison with the previous ones in [5] by simulation. Results of the test are shown indicating that an apparant better performance then those of previous ones in [5] is achive. The algorithm was applied in the computer-based urban traffic control system of a main street in Dalian City, and a satisfactory performance was obtained.
