Freeway incident management systems are an essential part of motorway operations. Efficient and co-ordinated detection and management of incidents reduces their adverse impacts on public safety, mobility, and the economy in general. Automatic incident detection tools confront various problems, such as lack of proper validation, high false alarm rates and non-integration with freeway control systems. This has led to a downturn in the adoption and utilisation of incident management tools at a wide scale. As part of the EU-funded trans-European project CORVETTE, the objectives are to develop, test, and implement integrated incident detection and control mechanisms that provide an adequate level of performance for a wide spectrum of traffic conditions. The approach, currently being developed, uses an innovative multiple-level data fusion structure to obtain high added-value and integration with motorway line control. A prototype framework has been developed and tested on several motorway stretches in Bavaria. For the covering abstract see ITRD E122427.
