Usefulness of Salt for Winter Road Maintenance.

Probabilistic Weather Forecasting for Winter Road Maintenance

Road maintenance is one of the main problems Departments of Transportation face during winter time. Anti-icing, i.e. applying chemicals to the road to prevent ice formation, is often used to keep the roads free of ice. Given the preventive nature of anti-icing, accurate predictions of road ice are needed. Currently, anti-icing decisions are usually based on deterministic weather forecasts. Howe...

Automated Winter Road Maintenance Using Road Surface Condition Measurements

Real-time measurement of tire-road friction coefficient is extremely valuable for winter road maintenance operations and can be used to optimize the kind and quantity of the deicing and anti-icing chemicals applied to the roadway. In this project, a wheel based tire-road friction coefficient measurement system is first developed for snowplows. Unlike a traditional Norse meter, this system is ba...

Predicting Weather and Road Conditions: An Integrated Decision Support Tool for Winter Road Maintenance Operations

Winter road maintenance practitioners have expressed a strong interest in obtaining weather and road condition forecasts and treatment recommendations specific to winter road maintenance routes. These user needs led the Federal Highway Administration (FHWA) Office of Transportation Operations Road Weather Management Program to support the development of a prototype winter road Maintenance Decis...

Work domain modeling to support winter road maintenance operations

This thesis presents an application of Work Domain Analysis (WDA) to the domain of Winter Road Maintenance Operation (WRM). WDA is the first phase of Cognitive Work Analysis (CWA), a methodology for analyzing complex socio-technical systems. WDA can help to structure system information in a manner that is meaningful for decision making and computer-based information system design. The Abstracti...
