TRAFFIC CONDITION PREDICTION METHOD AND DEVICE THEREFOR, AND RECORDING MEDIUM HAVING RECORDED TRAFFIC CONDITION PREDICTION PROGRAM THEREON

摘要

PROBLEM TO BE SOLVED: To accurately predict traffic conditions by a short processing. SOLUTION: Latest data to be used for prediction are gathered and the gathered data are added to the head of time sequential data 201. Then, a latest time sequential pattern set 220 is prepared and a time sequential pattern table 230 is updated. Then, a latest time sequential data key 210 is prepared by using the time sequential data 201. From the time sequential pattern table 230, a most frequently appearing prediction value is retrieved. The prediction value is decided as the prediction value of the traffic conditions.
