Claim One:
1. A traffic-information providing device, comprising: a traffic-information database for recording past traffic-information time-sequence data, a day factor input device for inputting plural day factors on a prediction-target day, or date of said prediction-target day, either one of the prediction-target day or the date of the prediction-target day being arranged to be inputted in a mutually exclusive manner by a tab-type interface indicated on a display screen of the day factor input device so as to permit arbitrary editing of the day factors prediction target designating unit for inputting a prediction target route, a traffic-information calculation device for determining, based on said past traffic-information time-sequence data, traffic-information time-sequence data for the prediction target route according to each of said plural day factors inputted from said day-factors input device, a day factor database for storing day-factor classifications for road links, at least one of the links being arranged to include an area for which past traffic-information time sequence data has been stored in the traffic-information database, and a day factor classification setting unit for updating day-factor classifications stored in the day-factor database, wherein the day factor classification setting unit includes: a route input device for specifying the prediction-target route between two locations for which a day factor is to be modified due to data input operation through the display screen of the day factor input device, and day-factors classification specifying unit for setting day-factors classifications for each of said routes at which day-factor has been designated, wherein said day-factors classification specifying unit sets said day-factors classifications for each prediction-target route specified by said route input device.
