... and Federal Highway Administration. Abstract Performance standards are used extensively at INDOT to establish and measure performance in many different operations. One area that extensively uses standards is in Maintenance Operations. Currently INDOT has defined three Level of Service(LOS) standards for winter operations. These standards describe pavement conditions during winter weather events and are subjective in nature. A more quantifiable standard would improve the evaluation of winter operations. This project produced a performance standard based on vehicle speeds during a storm impact period. The period is defined as the time between the beginning and end of a winter storm. The performance standard is modeled after the INDOT mobility standard and applies to interstate routes. It is easily implementable and can be used to identify ineffective snow and ice removal efforts and provides real time feedback. 17.
