| 摘 要： | 通过交通量预测的方法,可以在突发事件情况下评估事件对高速公路网的交通影响。各种预测算法的共同特征,需要一定的历史数据支持。在同一算法中,对历史信息吸收得越多,其预测往往越准确。作者借用图像压缩的原理,从历史交通数据中抽象出历史交通状态演化模式,并用压缩码表示该演化模式。通过对压缩码的检索,可以快速提取与当前演化模式相近的历史数据,通过这些演化模式相近的历史数据,预测交通状态的变化趋势。试验证明,预测数据与真实数据具有良好的拟合度。

| Abstract: | The effect of an accident occurred on expressway on the expressway net can be estimated by the method of traffic volume forecasting.The common characteristic of forecast algorithms needs history data support,and an algorithm always forecasts more accurate by absorbing more history data.Referred to the theory of image compression,the history traffic volume evolvement mode was abstracted from history data and the evolvement mode was expressed by compressed code. History data similar to current traffic volume ... |
