Winter roads often lead to inferior conditions to drivers. The freezing and thawing cycle leads to a decreased friction coefficient in wet or snowy weather when compared to dry roads. This leads to an increase in possibility of traffic accidents during the winter. Therefore, collecting accurate information on road surface temperature is crucial to provide a safe and efficient winter road environment. This study collects surface temperature, atmospheric temperature, humidity, vehicular ambient temperature, and GPS data through a thermal mapping system. The collected data is transformed into a database format that can be analyzed, and the correlation between the road surface temperatures is identified using two statistical tests. These can provide great insights of necessary parameters for forecasting the road surface temperature by statistical results. KCI Citation Count: 0
