Abstract:

Road management agencies must adapt to constraints on operating resources through adjustment to services such as winter patrolling, plowing and salting. While the resulting cost savings can be readily estimated, the adjustment must also consider changes to societal benefits and these may be difficult to estimate.

Improved availability of high resolution highway operations, weather and traffic data have allowed the modeling of relationships among road surface conditions, weather, accident rate and traffic flow that can be applied to estimate the benefits of winter maintenance under varying service levels.

This study combines previously developed road safety models with empirical characterizations of road surface conditions over a winter season to estimate the relative costs and benefits of winter maintenance on the highway network in Ontario. Case studies are used to illustrate the influence of service level and winter severity on the benefit: cost consideration in adjusting operating resources.
