Feng, F. and Fu, L. (2014). “Winter Road Surface Condition Forecasting.” J. Infrastruct. Syst. , 10.1061/(ASCE)IS.1943-555X.0000241 , 04014049. Winter Road Surface Condition Forecasting This study has attempted to address a challenging problem in winter road maintenance, namely road surface condition (RSC) forecasting. A novel conceptual framework for short-term road surface condition forecasting is proposed. This framework is designed to consider all important conditional factors, including weather, traffic, and maintenance …Read More

Kwon, T. J., and Fu, L. (2013) “Evaluation of alternative criteria for determining the optimal location of RWIS stations”, Journal of Modern Transportation, vol. 21., pp 17-27 Abstract: This article presents a comprehensive framework for determining the location of road weather information system (RWIS) stations over a regional road network. In the proposed methodology, the region is divided into a grid of equal-sized zones which are considered as the minimum spatial unit for allocating a …Read More

(2013) “Effect of Winter Weather and Road Surface Conditions on Macroscopic Traffic Parameters”, accepted for publication in Transportation Research Record: Journal of the Transportation Research Board, National Research Council. Washington D.C. Abstract: This paper presents an empirical study focusing on identifying the main factors that affect the capacity and free-flow-speed (FFS) of urban freeways under inclement winter weather conditions. The weather and …Read More
