A time-prediction method and apparatus

The present invention provides a method and apparatus for time prediction relates to dynamic traffic information services, can be in a non-normal traffic conditions, improve the accuracy of travel time predictions. Including: the departure point to the destination path between the divided N links; based on historical travel time N links in the link between the degree of correlation N link is divided into a set of links X; X Get a chain Road set for each set of links corresponding to the link matrix, historic moment for the previously projected time time a preset period of time; for X number of links in the collection of each set of links corresponding to the link matrix ARIMA training X get a set of links in the prediction time travel time; X Get a set of links in the prediction of time and travel time as a predicted time of departure to predict travel time between destinations. The time prediction method and apparatus for predicting travel time.
