Zusammenfassung: | PURPOSE:To obtain a traffic volume prediction having an excellent follow-up performance even when marked fluctuations in the traffic volume is produced by external disturbances. CONSTITUTION:An actual traffic volume up to a fixed time from a current traffic volume detected value measured with a traffic counter 11 is determined with an arithmetic operation section 12. A traffic volume whose time zone pattern is identical to this actual traffic volume is incorporated from a traffic volume fluctuation pattern generation section 13 so that a fluctuation constant arithmetic operation section 14 may determine a fluctuation constant. Fuzzy inherence means 15 and 16 make a traffic volume prediction based on fuzzy inherence from this fluctuation factor and the current traffic volume. |
