I. Introduction
Transportation systems rely heavily on the condition of the roads for both passenger and freight transport. Road conditions define the quality of rides, congestion, accidents and many other related aspects. In order to improve the safety and reliability of road based travel, factors such as road visibility, surface condition and weather are highly influential. Thus the quality of the road condition is crucial for all stakeholders such as consumers, public transportation departments and emergency responders for decision making and risk mitigation [1].
