Sustainability in transportation requires that the three "pillars" of societal needs, environmental protection and economic costs and benefits, should be balanced. Yet, the tools currently available deal only peripherally with transportation operations and maintenance, and with winter maintenance in particular. It is planned to further develop a checklist tool that exists in preliminary form by working with winter maintenance professionals from states, cities and counties to determine how best to refine the existing tool in a variety of areas. The deliverables of this project will be a refined winter maintenance sustainability checklist tool, and the final report detailing the findings of the study. |
