Title:

Performance Audit Method for Winter Maintenance

Abstract:

There is a need for a simple performance audit method that measures the consequences and value of correct and incorrect decisions to salt roads. A type 1 error is defined as when roads should have been salted but were not. A type 2 error is when roads were salted when they need not have been. Up to now these checks have been applied to the forecast providers only. This paper suggests that verification statistics can also be used to measure the performance of highway agencies and private consultants or who ever decides when roads should be salted.
