A Quality- and Priority-Based Traffic Information Fusion Architecture.

A novel architecture is proposed that enables the detection, automatic priority-based processing and validation of event messages, and data fusion of periodically gathered probe data to facilitate various Intelligent Transportation System (ITS) applications. Floating car data and mobile phone data are processed in a multilevel Event Validator service to identify roadtraffic events. Based on the data quality and the priority of the identified event, it is either sent to other cars in the area or processed further using additional information to achieve a higher reliability of the detected event.
