介绍了马尔柯夫过程的理论及方法，并将其预测模型和稳定状态方程应用于道路交通噪声变化的定量预测上，其预测结果与研究市区道路交通噪声变化的实际情况相一致，表明用马尔柯夫过程定量预测道路交通噪声变化是可行的。
The theory and method of Markov process are introduced, and its prediction model and steady state equation are applied to the quantitative prediction of road traffic noise change. The prediction results are consistent with the actual situation of urban road traffic noise change, Markov process quantitative prediction of road traffic noise changes is feasible.
