To detect a detailed congestion condition and provide the detected information while minimizing an information communication load from each vehicle to an information center in a system that aggregates information from individual vehicles traveling on a road at the information center and provides congestion information.SOLUTION: A system that provides road congestion information includes: information transmission means 20 to 24 mounted on individual vehicles 10 to 14; and an information center that receives and acquires information transmitted from the information transmission means of the individual vehicles. The information transmission means of the individual vehicles is configured to identify which of multiple preset speed ranges a vehicle speed is within when the vehicle speed of each vehicle is below a predetermined speed, and to transmit information on the identified speed range of the vehicle speed, information on the travel position and time, and identification information of each vehicle to the information center. The information center determines whether or not the congestion is present or not and a sort of congestion for each road section based on information transmitted from the individual vehicles, and provides the congestion information to any recipient.SELECTED DRAWING: Figure 1

    【課題】 道路を走行中の個々の車両からの情報を情報センターにて集計して渋滞情報を提供するシステムに於いて、個々の車両から情報センターへ情報通信負荷ができるだけ小さく抑えつつ、詳細な渋滞の状況を検出し、その情報を提供する。【解決手段】 道路の渋滞情報を提供するシステムは、個々の車両10~14に搭載された情報送信手段20~24と、個々の車両の情報送信手段から送信された情報を受信して収集する情報センターとを含み、個々の車両の情報送信手段が、各車両の車速が所定速度以下であるときに、車速が、複数の予め設定された速度域のいずれに入っているかを識別し、車速の識別された速度域の情報と、走行位置と時刻の情報と、各車両の識別情報を情報センターへ送信するよう構成され、情報センターが、個々の車両から送信された情報に基づいて道路区間毎に渋滞の有無と渋滞の種類とを判定し、その渋滞情報を任意の提供先に提供する。【選択図】 図1
