9.2.3.1: Determine Winter Roadway Treatment Needs

This process shall determine the need for roadway treatment based on current and forecasted weather information, current usage of treatments and materials, available resources, requests for action from other agencies, and recommendations from the Provide M&C Maintenance Decision Support function, specifically under winter conditions. This shall include winter maintenance such as plowing, treating, anti-icing, etc. Once roadway treatment needs are established by this process, the recommended treatment shall be output to the Schedule M&C Activities or directly to the Manage M&C Vehicle Fleet function, depending upon the urgency of the request. A record of winter maintenance needs shall be output to another process for archival.

This process is associated with the Maint and Constr Management Center physical object.
