In this embodiment, a description will be given on the assumption that an existing traffic situation prediction system is used, and numerical data of a traffic situation prediction result can be obtained from the system.

First, a request from a user is interpreted (step 101). Using a telephone, a portable terminal, a personal computer, or the like, the user sends a road for which traffic condition information is to be known, a time at which predicted information is required, and the like to the predicted traffic condition distribution center. To give a concrete example, the user first calls the predicted traffic situation information distribution center using a mobile phone, enters the name of the road whose traffic situation information is to be known in text, and sets the time when the user wants to know the predicted information. Is input numerically and the information is sent to the center. On the basis of the transmitted information, the center determines when and where to predict traffic conditions.

Next, data corresponding to the determined information is predicted (step 102). This is called prediction data to be distributed, that is, distribution prediction data.

Next, the distribution prediction data is converted so that it can be received by the terminal owned by the user (step 10).
3). Specific examples include conversion to voice data and conversion to text.

Finally, the converted wiring prediction data is distributed to the user (step 104).

FIG. 2 is a sequence diagram showing an actual use scene of the present embodiment.

When the user calls the predicted traffic situation distribution center using a mobile phone, the incoming call is confirmed, and the user enters the text of the name of the road (use road name) for which he wants to know the traffic situation information, Send the time (use time) for which you want to know information as a numerical value. The predicted traffic condition information distribution center detects the transmitted use road name text and the use time, predicts the road and the traffic condition concerned, creates distribution prediction data, and converts the distribution prediction data into, for example, voice data. Deliver to users. Note that “* #” at the end of the data to be transmitted in FIG. 2 is a symbol indicating the end of the transmission data.

Referring to FIG. 3, an apparatus for predicting traffic condition information distribution according to an embodiment of the present invention comprises a user request interpreting unit 201, a traffic condition predicting unit 202, a distribution predictive data conversion unit 203, and a distribution predictive data distribution unit 204.
