Snow Removal and Weather Related Operations

VDOT NOVA uses information from weather information providers (the weather service and surface transportation weather service providers) and from RWIS stations to provide current and forecast weather information that can be fused with other data sources and used to support advanced decision support systems that increase the efficiency and effectiveness of winter maintenance operations (for example snow removal). The continuing updates of road condition information and current temperatures are used by VDOT NOVA system operators to more effectively deploy road maintenance resources, issue general traveler advisories, issue location specific warnings to drivers using the Traffic Information Dissemination market package, and aid operators in scheduling work activity. Efforts are also underway to enhance automated treatment systems such as treatments for fog dispersion, anti-icing chemicals, etc. When the environmental sensors detect adverse conditions, the automated treatment system will be activated and drivers will be notified of the system activation through dynamic message signs.
