This article describes a system and methods by which real time traffic flow information gathered from devices in vehicles could be used to ratify and update information on incidents and congestion on the road network. The system uses expected behavioural patterns associated with different incident types to assess actual information gathered from vehicles travelling through the area of the incident to work out whether the incident remains current, has moved location at all or completely disappeared. The information can also be used to predict the onset of incidents, again by comparing vehicle movement data gathered from on-board devices and matching it with signatures of incidents known to affect traffic flow such as accidents or roadworks.
