Weather and Climate in Road Safety and Winter Road Maintenance

Participants of this webinar will gain a basic level of knowledge and awareness of main weather sensitivities on the road transportation sector. Examples of possible impacts that weather and climate can have on road transportation will be presented. Particular attention will be paid to understanding the sensitivity of road safety and winter road maintenance to variable weather. Case studies, as well as an overview of a Winter Severity Index tool developed for a Canadian winter road maintenance authority, will also be presented.


  • PART 1: Overview of climate change projections for Canada
  • PART 2: Weather and climate sensitivities for the transportation sector
  • PART 3: Case study: the impact of climate change for road safety
  • PART 4: Case study: the impact of weather on winter road maintenance and what this may mean in a changing climate
  • PART 5: Question and answer period 

Learning Objectives

  • Identify main weather sensitivities and provide examples of possible impacts of a changing climate for various facets of the transportation sector
  • Identify and describe general trends in the relationship between weather, climate change, and road transportation
  • Understand the sensitivity of road safety and winter road maintenance to variable weather
  • Reflect on the value of a winter severity index tool for enabling informed decision-making by transportation authorities

Target Audience

  • Road authorities and professional contractors interested in the impacts of weather and climate on the transportation sector.
  • Winter road maintenance professionals interested in learning about documenting the relationship between weather and winter road maintenance activities.
