From page 6... ... In any climate, the achievable LOS is limited by the rate of precipitation, cycle time capability, sustainability of the maintenance effort, site conditions that may cause road closure, and materials options. Higher LOS for similar weather conditions can be provided with shorter cycle times and the use of straight ice control chemicals. Read the entire page →
From page 7... ... Traffic characteristics appear to be less important than weather and site conditions; however, higher traffic volume and speed can displace snow and ice control materials from the highway surface. • Frequency of Snow and Ice Events – Low – Moderate – High • Severity of Winter Pavement Exposure – Mild – Moderate – Severe • Wintertime Precipitation – Type – Rate • Urban Influence – Small – Medium – Large – Industrial • Water Influence – Minor – River – Lake – Ocean • Elevation/Large Scale Topography – Plain – Rolling – Mountainous TABLE 2 Climate-related items Light Rain.
