Traffic information management system
First Claim
1. A road traffic information management system, comprising:
- first processing means for recognizing a transition pattern of the necessary travel time for a mobile unit for each unit road;
second processing means for recognizing a route for the mobile unit including one or more unit roads by communicating with an instrument mounted on the mobile unit;
third processing means for searching, for each unit road included in the route recognized by the second processing means, for a resembling pattern that resembles a reference pattern, the reference pattern being the transition pattern within a reference time zone that has a duration and ends at a current time, the resembling pattern being a past pattern of the transition pattern within a past time zone that precedes the reference time zone and has the same duration as the reference time zone;
fourth processing means for predicting the necessary travel time required for the mobile unit to travel the route recognized by the second processing means or a unit road included in the route based on the resembling pattern retrieved by the third processing means; and
communication processing means for transmitting traffic information including the necessary travel time predicted by the fourth processing means to a navigation system mounted on the mobile unit for which the route is recognized by the second processing means.

Abstract
To provide a system that can provide traffic information to drivers of automobiles or the like with high prediction precision. In a traffic information management system according to the present invention, a first processing unit 110 recognizes a transition pattern of the necessary travel time for an automobile 20 for each unit road. A second processing unit 120 recognizes a route including one or more unit roads by communicating with a navigation system 200. For each unit road included in the route, a third processing unit 130 searches for a “resembling pattern” that resembles a “reference pattern” from a “past pattern”. A fourth processing unit 140 predicts the necessary travel time required for the automobile to travel the route or a unit road included in the route based on the resembling pattern. A communication processing unit 150 transmits traffic information including the predicted necessary travel time to the navigation system 200.

14. A method for managing road traffic information, the method comprising the steps of:
-
(a) recognizing a transition pattern of a necessary travel time, via processing unit, for a mobile unit for each unit road; (b) recognizing a route for the mobile unit including one or more unit roads by communicating with an instrument mounted on the mobile unit; (c) searching, for each unit road included in the route recognized for the mobile unit, for a resembling pattern that resembles a reference pattern, the reference pattern being the transition pattern within a reference time zone that has a duration and ends at a current time, the resembling pattern being a past pattern of the transition pattern within a past time zone that precedes the reference time zone and has the same duration as the reference time zone; (d) predicting the necessary travel time required for the mobile unit to travel the route recognized in the step (b) or a unit road included in the route based on the resembling pattern searched in the step (c); and (e) transmitting traffic information including the necessary travel time predicted in the step (d) to a navigation system mounted on the mobile unit for which the route is recognized in the step (b). - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26)

27. A road traffic information management system, comprising:
-
first processing means for recognizing a transition pattern of the necessary travel time for a mobile unit for each unit road; second processing means for recognizing a route for the mobile unit including one or more unit roads by communicating with an instrument mounted on the mobile unit; third processing means for searching, for each unit road included in the route recognized by the second processing means, for a resembling pattern that resembles a reference pattern recognized by the first processing means within a reference time zone in a past pattern recognized by the first processing means within a past time zone that precedes the reference time zone and has the same duration as the reference time zone; fourth processing means for predicting the necessary travel time required for the mobile unit to travel the route recognized by the second processing means or a unit road included in the route based on the resembling pattern retrieved by the third processing means; and communication processing means for transmitting traffic information including the necessary travel time predicted by the fourth processing means to a navigation system mounted on the mobile unit for which the route is recognized by the second processing means, wherein the third processing means recognizes the resemblance between the reference pattern and the past pattern, determines a predetermined threshold for the past pattern with the past time zone in accordance with the time difference between the reference time zone and the past time zone, and retrieves as the resembling pattern, the past pattern for which the resemblance to the reference pattern is equal to or higher than said predetermined threshold.
