<p><P>PROBLEM TO BE SOLVED: To provide a system and a method for traffic prediction based on space-time relation. <P>SOLUTION: The system comprises: a section spatial influence determining section for determining, for each of a plurality of sections to be predicted, spatial influences on the section by its neighboring sections; a traffic prediction model establishment section for establishing, for each of the plurality of sections to be predicted, a traffic prediction model by using the determined spatial influences and historical traffic data of the plurality of sections; and a traffic prediction section for predicting traffic of each of the plurality of sections to be predicted for a future time period by using real-time traffic data and the traffic prediction model. According to the system, a spatial influence of a section can be used as a spatial operator and a time sequence model can be incorporated, such that the influences on a current section by its neighboring section for a plurality of spatial orders can be taken into account. Thus, the traffic condition in a spatial scope can be measured more practically, so as to improve accuracy of prediction. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
