Abstract: Methods for determining need for treating a vehicle travel surface include sensing, at a first time, a characteristic of a vehicle travel surface from a mobile sensor. Sensed characteristics include temperature, friction coefficient, material volumetric buildup, e.g., composition, such as an amount or percentage of ice or snow, density, depth, freeze point and chemical concentrations. The sensed characteristic is recorded as a first measurement in a database, and GIS information correlating a location with the first measurement is attached. The characteristic of the vehicle travel surface is sensed at a second time, at the location, and recorded in the database, for example as a second measurement. GIS information correlating the location with the second measurement may be attached, and the first and second measurements compared.

Abstract: A surface condition sensing and treatment system includes a transmitter for transmitting electromagnetic radiation (EMR) toward a surface material disposed upon a vehicle travel surface. Reflected EMR is received and signals indicative of the reflected EMR are processed to produce output corresponding to a characteristic of the surface material. Characteristics include friction, depth and composition, including ice present in the surface material. Sensing may be locally or remotely, automatically or manually initiated. The system may include a display and at least one computer with a database of surface material characteristics, historical, environmental and GIS positional information. Sensed characteristics processed with database information may determine a surface treatment, according to a selected outcome or level of service. A spreader system applies the surface treatment responsive to local, remote, automatic or manual command.
