RAIDER is a research project aiming to improve incident detection systems in terms of the detection quality and costs of the system and individual components such as sensors, data fusion and incident detection algorithms. The quality of existing systems and their components are reviewed against the user needs and requirements from National Road Authorities. Generic specifications are derived for sensors, data fusion and incident detection algorithms, based on which recommendations are made for necessary improvements of existing systems.
A second path is also followed to assess the feasibility, costs and benefits of innovations in the near future in roadside sensors, nomadic devices, and in-vehicle devices. Alternative system concepts for incident detection are explored to incorporate and fuse data from mobile devices. The quality criteria from the first approach also apply here as constraints on the quality of the devices.
Experts from the National Road Authorities are consulted early in the project to select their top priority types of incidents and most pressing issues as reference cases for research. These could be for example; hard shoulder monitoring and the detection of accidents and traffic congestion on highways. Stakeholder consultations and two workshops with experts from the Road Authorities are planned to ensure the necessary input for the project and the dissemination and exploitation of the results.
The project does not attempt to focus on any particular incident detection systems or Road Authority, because custom solutions are not easily transferable to other systems and Road Authorities. Instead the project follows a methodology to deliver results that apply to all Road Authorities:
Generic specification of the quality requirements for sensors, data fusion and incident detection algorithms, in function of the user needs and requirements on incident detection functionality and performance.
Feasibility assessment of innovative roadside sensors, nomadic devices and in-vehicle systems to improve incident detection.
These results can be applied by Road Authorities to assess the performance of their existing incident detection systems, identify necessary improvements, and define specifications for tendering. The specifications and feasibility assessment also provide the necessary input for cost benefit analyses of such improvements.
