摘要： An incident resolution judgment system and method are provided which reduce processing load on a traffic information center included in an incident detection system. When an incident occurs, the traffic information center generates an incident resolution judgment condition, which is used by each vehicle to judge whether the incident is resolved, and transmits the generated incident resolution judgment condition to each vehicle. Each vehicle judges in accordance with its travel history information and the received incident resolution judgment condition whether the incident is resolved. When the incident is judged to be resolved, each vehicle notifies the traffic information center that the incident is resolved. In accordance with incident resolution detection results produced by a plurality of vehicles, the traffic information center forms a final judgment to indicate that the incident is actually resolved and notifies each vehicle of incident resolution.

摘要： An object of the present invention is to provide a traffic information system that detects an unexpected incident such as a traffic accident or construction work from traffic information about surrounding road links. Historical traffic information is used to perform component analysis for a group of links that are targets of unexpected incident detection, and recovered traffic information for the historical traffic information is determined from computed top bases of the traffic information about the group of links. Difference statistical traffic information is generated from the difference between the historical traffic information and its recovered traffic information. For real-time traffic information, recovered traffic information for the real-time traffic information is determined from the top bases. The difference between the real-time traffic information and the recovered traffic information is compared with the difference statistical traffic information, and if the difference of the real-time traffic information is larger, the occurrence of an unexpected incident is determined.
