WWxM TSO was developed by AASHTO - American Association of State Highway and Transportation Officials as the Snow and Ice Cooperative Program (SICOP). SICOP, once a stand-alone collective, has become one of AASHTO’s technical service programs, now the Winter Weather Management Technical Service Program. A principal mission of the WWxM is to ensure that the requisite testing and evaluation of potentially implementable international or domestic winter maintenance technologies are performed and that the results of these efforts are presented and disseminated in such a manner that beneficial winter maintenance technologies are easily understood and integrated into individual state and municipal operational programs. Beyond this principal mission, the WMP works toward establishing a sustainable systems approach to snow and ice control in the
United States–one involving the vehicle, the driver, the equipment, the materials and practices, and the receiving environment for managing roadway and bridge snow and ice.
