• accident analysis, and characteristic of the accidents in winter period;
• traffic signal optimisation to improve road safety;
• economic effects of winter and winter maintenance, better traffic flow, travel time reliability;
• communication and road user information, social media, user feedbacks, complaint management;
• driver education for winter driving;
• global advice and information to users when travelling.

5. Winter maintenance management and planning
Papers shall deal with the following topics:
• road users’ needs; how to define the right level of service;
• understanding the economic impact of accidents; defining the acceptable level of risk;
• integrating winter service into a sustainable development strategy;
• cost-benefit: achieving the optimum balance?
• improving training for winter service professionals;
• strategic planning and organization (what rules, standards, evaluation, legal aspects);
• relationships between all parties / stakeholders (managers, operators, road users etc.);
• quality and performance management;
• outsourcing the service versus in-house implementation.

6. Equipment and products
Papers shall deal with the following topics:
