Problems solved by technology

[0004] However, if only the traffic volume model of the day is compared with the traffic volume accumulation model in the common time zone, it is possible to extract only the traffic volume accumulation model with a low degree of similarity
Therefore, the prediction accuracy of traffic volume is not high, so that the purpose of alleviating traffic jams cannot be effectively achieved.

Embodiment Construction

[0044] figure 1 The traffic information management system in the illustrated embodiment of the present invention includes a navigation system (navigation and positioning system) 200 mounted on an automobile (mobile body) 20, and a vehicle detection device 300 installed on a road through a network. A traffic information management server (hereinafter referred to as a 'server') 100 that communicates.

[0045] figure 1 The illustrated traffic information management system includes a first processing unit 110 , a second processing unit 120 , a third processing unit 130 , a fourth processing unit 140 , and a communication processing unit 150 . Each unit is constituted by CPU, ROM, RAM, and other various circuits as hardware.

[0046] The first processing unit 110 recognizes the movement of the moving object on the 'first road' where the vehicle detection device 300 is installed by direct communication with the vehicle detection device 300 or indirect communication through the VIC...

Abstract

Provided is 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.

Description

technical field [0001] The invention relates to a system for managing road traffic information. Background technique [0002] Conventionally, for example, as described in Japanese Gazette No. 2002-298281 published in 2002, there has been disclosed a method of predicting traffic volume for the purpose of alleviating traffic congestion or the like. [0003] According to this method, the traffic volume model is stored and held in the memory as a "traffic volume accumulation model" on a daily basis. In addition, in a common time zone such as from 10:00 to 11:00, a traffic volume accumulation model similar to the current-day traffic volume model for predicting the traffic volume is searched / extracted from the memory. Then, based on the extracted traffic volume accumulation model, the traffic volume after a predetermined time is predicted from the prediction time. [0004] However, if only the traffic volume model of the current day and the traffic volume accumulation model are ...
