The present invention relates to a method for displaying traffic information related to a road on which a vehicle is traveling by using a navigation system, and to a method for generating traffic information reflecting a change in traffic flow so as to display real-time traffic information and change progress information on traffic flow from a previous time point to a current time point as time-based change information. A method for generating a traffic information summary map, according to the present invention, comprises the method for generating traffic information reflecting a change in traffic flow, in a navigation system displaying road traffic information including speed, the method for generating traffic information comprising the steps of: deriving first traffic flow information from a first time point to a second time point for each link; deriving second traffic flow information from the second time point to a current time point for each link; deriving a mean speed for each link from the first traffic flow information and the second traffic flow information; deriving traffic flow change progress information from the first traffic flow information and the second traffic flow information; and generating traffic information by combining the mean speed and the traffic flow change progress information for each link.

    La présente invention concerne un procédé permettant d'afficher des informations de circulation associées à une route sur laquelle un véhicule se déplace à l'aide d'un système de navigation, et un procédé de génération d'informations de circulation reflétant une variation de flot de circulation de façon à afficher des informations de circulation en temps réel et des informations de progression de variation associées au flot de circulation d'un instant précédent à un instant actuel en tant qu'informations de variation reposant sur le temps. Selon la présente invention, un procédé de génération de carte de résumé d'informations de circulation comprend le procédé de génération d'informations de circulation reflétant une variation de flot de circulation, dans un système de navigation affichant des informations de circulation routière comprenant la vitesse, le procédé de génération d'informations de circulation comprenant les étapes consistant à : dériver des premières informations de flot de circulation d'un premier instant à un second instant pour chaque liaison ; dériver des secondes informations de flot de circulation du second instant à un instant actuel pour chaque liaison ; dériver une vitesse moyenne pour chaque liaison des premières informations de flot de circulation et des secondes informations de flot de circulation ; dériver des informations de progression de variation de flot de circulation des premières informations de flot de circulation et des secondes informations de flot de circulation ; et générer des informations de circulation en combinant la vitesse moyenne et les informations de progression de variation de flot de circulation pour chaque liaison.

    본 발명은 내비게이션을 통해 주행중인 도로에 관한 교통정보를 표시하는 방법에 관한 것으로서, 실시간 교통정보 뿐만 아니라 이전시점에서 현재시점까지의 교통 흐름의 변화추이정보를 시간에 따른 변화정보로 표출하기 위한 교통흐름의 변화를 반영한 교통정보 생성방법에 관한 것이다. 본 발명의 교통정보 요약맵 생성방법은 내비게이션에서 속도를 포함하는 도로 교통정보를 표시함에 있어서, 각 링크별로 제1시점에서 제2시점까지의 제1교통흐름정보를 도출하는 단계, 각 링크별로 제2시점에서 현재시점의 제2교통흐름정보를 도출하는 단계, 제1교통흐름정보 및 제2교통흐름정보로부터 각 링크별로 평균속도를 도출하는 단계, 제1 및 제2교통흐름정보로부터 교통흐름 변화추이정보를 도출하는 단계 및 각 링크별로 평균속도와 교통흐름 변화추이정보를 결합하여 교통정보를 생성하는 단계를 포함하는 것을 특징으로 하는 교통흐름의 변화를 반영한 교통정보 생성방법을 포함함에 기술적 특징이 있다.
