How to improve snow fighting by using performance management and level of service
The consequences of winter maintenance budgets include impacts to safety, longer
term effects on pavement quality, and personnel and driver satisfaction. Generally, better budgets can support better
performance standards and result in better mobility and safety, and any
reduction to budget would lead to a decline.
But how budget is linked to performance, safety, and mobility is poorly
Road agencies are required to develop performance measures to secure funding and a
National Cooperative Highway Research Program (NCHRP) project is currently developing a guide to selecting appropriate winter
performance measures. Agencies adopting
performance measures will be challenged to set service level targets without
knowledge of the link between the selected targets and safety and mobility
What is the trade off between mobility and safety, especially in the case where an
agency must choose between one or the other, like for winter road closure?
are pressing needs in the area of snow fighting performance management and
level of service:
- What are the impacts of implementing
levels of service on highway safety and mobility when applied to snow fighting?
How should we set service level targets for snow fighting with understanding of
the link between the selected targets and safety and mobility outcomes.
- Explore the effects on snow fighting
in the context of the new and broader performance management rules. Where are
the opportunities to improve? Where are the barriers to implementation? What
are the resource needs to effectively execute it?
- Examine the various consequences of changes
to winter maintenance budgets including safety effects and longer term effects
on pavement quality, personnel, and customer satisfaction.
- When is it best to close a road
before cars begin to be trapped? Develop
holistic methods to decide when it is best to close a road.
