Abstract

There is provided a traffic information output system capable of reducing or eliminating the burden on a user when the searched route and the traffic information on the route are outputted. The traffic information output system comprises a moving cost prediction unit 213 which predicts a moving cost of the route according to a reference time point indicated in a change pattern, and a moving cost output control unit 214 which outputs, to the output device, the prediction moving cost and change time point interfaces P27 and P28 for outputting a prediction moving cost which is a moving cost predicted according to a post-change reference time point.

Claims

1. A traffic information output system comprising:

an input device and an output device;

a storage unit which stores a change pattern of a moving cost of a past moving cost;

an input information recognition unit which recognizes a reference time point and route determination information for determining a route, the reference time point and the route determination information being entered via the input device;

a moving cost prediction unit which predicts a moving cost of the route according to the reference time point indicated in the change pattern to generate a prediction moving cost; and

a moving cost output control unit which outputs, to the output device, the prediction moving cost and outputs a change time point indication for outputting a post-change prediction moving cost which is a moving cost predicted according to a post-change reference time point obtained by shifting the reference time point by a specified time,

wherein

the moving cost prediction unit calculates a change interval based on the change pattern so that a maximum value of an increase or decrease in prediction moving cost in some or all areas of the route is equal to or greater than a predetermined first threshold value, and

recognizes a time point which is the change interval earlier or later than the reference time point, as the post-change reference time point.

2. The traffic information output system according to claim 1, wherein

the moving cost prediction unit calculates a change interval based on the change pattern so that a maximum value of an increase or decrease in prediction moving cost which is a moving cost predicted in some or all areas of the route is equal to or less than a predetermined second threshold value and

recognizes a time point which is the change interval earlier or later than the reference time point, as the post-change reference time point.

3. The traffic information output system according to claim 1, wherein

the moving cost prediction unit is configured to recognize a time point closest to the reference time point out of the time points having a predetermined change in prediction moving cost in some or all areas of the route as the post-change reference time point.

4. The traffic information output system according to claim 3, wherein

the moving cost prediction unit selects a time point closest to the reference time point out of the time points where a prediction moving cost in some or all areas of the route is equal to or less than a predetermined third threshold value as the post-change reference time point based on the change pattern.

5. The traffic information output system according to claim 3, wherein

the moving cost prediction unit selects a time point closest to the reference time point out of the time points where a prediction moving cost in some or all areas of the route is reduced by a predetermined fourth threshold value or more as the post-change reference time point.

6. A traffic information output method executed by a traffic information output system comprising an input device, an output device, and a storage unit which stores a change pattern of a moving cost of a past moving cost, the traffic information output method comprising:

an input information recognition step of recognizing a reference time point and route determination information for determining a route, the reference time point and the route determination information being entered via the input device;

a moving cost prediction step of predicting a moving cost of the route according to the reference time point indicated in the change pattern to generate a prediction moving cost; and

a moving cost output control step of outputting, to the output device, the prediction moving cost and outputting a change time point indication for outputting a post-change prediction moving cost which is a moving cost predicted according to a post-change reference time point obtained by shifting the reference time point by a specified time,

wherein

the moving cost prediction step further comprises calculating a change interval based on the change pattern so that a maximum value of an increase or decrease in prediction moving cost in some or all areas of the route is equal to or greater than a predetermined first threshold value, and recognizing a time point which is the change interval earlier or later than the reference time point, as the post-change reference time point.
