MODELING OF VEHICLE HEATS AND ITS INFLUENCE ON SURFACE TEMPERATURE OF DRY ROAD

Abstract

Vehicle heats were quantitatively evaluated by field and indoor experiments and formulized in this paper. The experimental results encouraged to create an ‘instantaneous vehicle heat model’ and a ‘time averaged vehicle heat model’. These two vehicle heat models were adapted to field weather and traffic data. As far as this simulation condition is concerned, there was little difference in the road surface temperatures calculated by these models.
It was founded that the difference in the pavement surface temperatures between a vehicle-passage area and a non vehicle-passage area cannot be disregarded any longer.
