发明名称 PREDICTION DEVICE OF DRIVING TIME REQUIRED
摘要 PROBLEM TO BE SOLVED: To provide a driving time prediction device capable of predicting a driving time precisely by combining a short period driving time prediction using traffic data of the day of prediction and a medium and long period driving time prediction by searching similar patterns. SOLUTION: An actual value of driving time is obtained by traffic information from a plurality of data collecting points 2 by a traffic data processing means 4 and a pattern of driving time is accumulated. The pattern of the short period driving time from the present to the time elapsed for a predetermined time is predicted by a short period driving time prediction means 7. The driving time pattern of the day of prediction is obtained by a driving time prediction means 8 from the short period driving time pattern and the time pattern of the actual value of the driving time up to the present time. A similar driving time pattern which is similar to the driving time pattern of the day of prediction is extracted from the accumulated driving time patterns, and a later driving time is predicted successively with the similar driving time pattern.
