The study that is the subject of this report was defined in the PIARC Strategic Plan 2012-2015 approved by the Council of the World Road Association.The report provides brief summaries of projects from around the world, presented in the form of use cases that are representative of innovative ways of collecting, distributing, and making use of mobile data to assist transportation officials in their winter maintenance operations and to provide information to the traveling public.The use cases or case studies were selected because it is the belief of the authors that, when deployed, any of the technologies described will have a positive impact on transportation safety, mobility, the environment, and/or more efficient use of human and material resources needed to carry out their winter maintenance duties. As an added bonus, these use cases generally result in the traveling public being better informed, which results in them making better travel choices and being more accepting of the technologies.
