Kwon, T. J., Fu, L., and Jiang, C. (2014). “RWIS Stations – Where and How Many to Install: A Cost Benefit Analysis Approach”, Proceedings of the 93rd Annual TRB conference, Washington D.C., Jan 12-16. Abstract This paper presents a cost-benefit based approach to the problem of finding the optimal location and density of road weather information system (RWIS) stations over a regional road network. The key contribution of the proposed …Read More
Perchanok, M., McClinktock, H., Fu, L., Thakali, L., & Huid, H. T. (2014). A Benefit-Cost Approach to Level of Service Standards for Winter Road Maintenance. Proceedings of the 14th International Winter Road Congress- World Road Association. Andorral la Vella, Feb 4-7. Abstract: Road management agencies must adapt to constraints on operating resources through adjustment to services such as winter patrolling, plowing and salting. While the resulting cost savings can be …Read More
Fu, L., Thakali, L, Kwon, T. J., & Usman, T. (2014). Winter Road Condition Classification and Reporting – A Risk Based Approach. Conference Proceedings of 14th International Winter Road Congress – World Road Association. Andorra la Vella, 4-7 Feb 2014 Abstract The paper presents a risk based approach for classifying the road surface conditions of a highway network under winter weather events. A relative risk index (RRI) is developed to …Read More

Proceedings of the 93rd Annual TRB Conference, Washington D.C., Jan 12-16. Abstract: In road safety research, a parametric approach is commonly applied in modeling road collisions, which have resulted in many different types of models such as Poisson, Negative Binomial and Poisson lognormal. …Read More
