Level of service (LOS) is the determined outcome that is the objective of snowfighting operations. LOS should be considered for in-storm and after-storm as separate measures. It is important that snowfighters move beyond inputs and outputs to focus on outcomes, the true measure of performance. Such measures can be visual, the presence of an ice/pavement bond, friction measures or various readings from sensors embedded in the pavement. Choice of strategy and materials will strongly influence outcomes.
