Winter weather ranges from severe ice storms to high accumulation snow events to typical events with mixed precipitation types and amounts with a wide range of impacts across the state. Missouri has areas ranging from sparsely populated rural to congested urban areas. With this diversity in mind and the data-driven culture of the Missouri Department of Transportation (MoDOT), the MoDOT Winter Severity Index process developed in this research effort provides a tool to accurately compare response practices, winter weather management, and performance across the various diverse regions of Missouri.126
