A quality- and priority-based traffic information fusion architecture

We propose a novel architecture, which enables the detection, automatic priority-based processing and validation of event messages and data fusion of periodically gathered probe data to facilitate various traffic applications. Floating car data and mobile phone data are processed in a multilevel event validator service to identify traffic events. Based on the data quality and the priority of the identified event, the event is either sent to other cars in the area, or processed further using additional information to achieve a higher reliability of the detected event.
