Planning for Winter Road Maintenance in the Context of Climate Change

This article explores climate change impacts on winter road maintenance (WRM) costs by calculating a winter severity index (WSI) using data from meteorological stations and maintenance expenditure records. A WSI was developed for Prince George, British Columbia based on historical weather and maintenance data, 1994-2012. To evaluate the impact of climate change on Prince George, the WSI was applied to historical weather observations and future climate simulations. It is estimated that average winter temperatures in the Prince George region will increase by 1.5°C-2.8°C leading to an increase in rain rather than snow. Overall, annual demand for winter maintenance activities in Prince George are projected to decrease by 13-22% by the 2050s resulting in an annual savings of between $689,000 to $1,166,000 CAD.
