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...

Markov Decision Processes for Road Maintenance Optimisation

This paper primarily focuses on finding a policy for maintaining a road segment. The paper presents two methods for finding such a policy. The first one is using a probabilistic Markov Decision Process in order to determine the optimal maintenance policy. The second method is used by the Road and Hydraulic Engineering Division (DWW). That policy however is not optimal but does not require an MD...

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...
