  • Strategies and tools designed to implement and mitigate the impact of weather on surface transportation activities. The identification of the three road weather management strategies is put forth with a definition of each strategy. The logical association of the strategy name with the definition should be made to reinforce later retention of the name and definition. This can be described that ‘advisory’ conveys information, ‘control’ places limits on use, and ‘treatment’ attempts to ameliorate the deteriorated conditions due to weather.

  • Principles and Tools for Road Weather Management Instructor Guide that ‘advisory’ conveys information, ‘control’ places limits on use, and ‘treatment’ attempts to ameliorate the deteriorated conditions due to weather. Key Message: Advisory Strategies provide information to users and managers of the transportation system on threats or changing conditions warranting a notification. Background Information: Dissemination of hazard advisories is conducted through various methods, including: Roadside message signs including dynamic message signs Telephone and cellular phone (e.g. 511) Highway Advisory Radio (HAR) Public web sites Radio and television Interactivity: None Notes: None
  • Principles and Tools for Road Weather Management Instructor Guide Advisory strategies: Nebraska DOR Control strategies: Charlotte, NC Treatment strategies: Montana
  • Principles and Tools for Road Weather Management Instructor Guide Key Message: Control strategies alter the state of roadway usage . Background Information: The road weather control is taken to be based upon some form of a weather input. This can be either a direct weather input or a characterization of a weather input that is necessary to support a decision by the transportation manager. Interactivity: None Notes: None
