PIARC Technical Committee B.2, "Winter Maintenance," working group B.2.1., "Transportation Management during Winter Events," was tasked with identifying noteworthy examples of cooperation within and between agencies responsible for winter maintenance management.

The working group asked PIARC members to submit by email short case studies demonstrating management integration efforts occurring at the intra-agency level (that is, within one agency) or at the inter-agency level (that is, between agencies, or across a regional or national border). The working group provided a template for this purpose.

A total of 10 case studies were received from six nations: Czech Republic (1 case study), Japan (3 case studies), Norway (2 case studies), Poland (1 case study), Scotland (1 case study), and the United States (2 case studies).

Four of these case studies represent intra-agency cooperative management efforts and six of these case studies represent inter-agency (in some cases, international) cooperative management efforts.
