Technical Reports Winter Service

This page lists technical reports of PIARC in the field of winter service. These publications are classified chronologically.

  • Advanced technology for data collection and infomation to users and operator

    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 [...]

  • Sustainability and Climate Change Considerations in Winter Operations

    This report has tried to summarize the knowledge of Climate Change Considerations in Winter Operations. The first step to this project was to source relevant literature on climate change and winter maintenance and sort it into six categories; Level of service for road owners, Maintenance of roads, Forecast models (RWIS), Indicators to find the variation of climate and operations, Different methods, and Infrastructure. Of the papers that were sourced 45 were selected and read and sorted into [...]

  • Crisis management of unusually severe and/or sustained snow events

    Extreme winter weather between 2008 and 2015 tested highway winter maintenance arrangements in many parts of the world. Unusually cold weather and significant snow events resulted in significant transport disruption and international media attention. From these challenges arose an opportunity to learn more about, and improve, the service provided to the road user. This report documents the good practice and can be used to aid the further development of winter maintenance resilience. The twenty-two [...]

  • Snow and Ice Databook 2014

    This fourth edition of the Snow and Ice Databook was produced to accompany the 14 th International Winter Road Congress held in Andorra. It compiles in a homogeneous and consistent format descriptions of practices for managing winter road conditions from nearly 30 countries. The four country-specific headings consist of: description based on geography, demographics and road network characteristics; potential climatological and meteorological phenomena; road management methods; and recent developments [...]

  • Impacts of changes in winter severity on winter maintenance

    Data from the past years indicate a significant evolution and change in temperature profiles, precipitation, and generally deviation from traditional seasonal cycles. For example snow events became more intense and sudden, and forecasts are getting more difficult. Based on Intergovernmental Panel on Climate Change (IPCC) scenarios, analyses are made for some regions showing that some significant changes are to be expected, specifically for winter months. Impacts of these changes on winter maintenance [...]
