Fog Warning System in Venice Region

The fog warning system build-up is one of the pilots of ROADIDEA project, under 7th Framework Programme of the European Union. The pilot was built and put in operation during the project. Fog Pilot is built by ARPAV, the meteorological service for Venice Region. This paper summarises the evaluation of the pilot and assesses the ex ante impacts. Especially the safety impact of the system is evaluated based on prior studies on similar systems and national accident statistics in Italy. Another emphasised evaluation line is the data and service output quality. System interface needs between Fog Pilot and other prospective systems hosted by other organisations, such as traffic carabinieri and traffic management centres of the region were assessed. Also some other technical and organisational aspects are evaluated. The challenges concerning the system architecture, looking at technical, organisational and economic issues, are discussed in the end.
