Title:

Study of Road Climate in Cities

Abstract:

During the winter season 1999/2000, a pilot project "road climate in urban areas" was carried out at different sites in Sweden. It was important to perform a comprehensive analysis of the local and microclimate environments to be able to include the thermal effects of suburban and urban environments into different kinds of road weather related models. The project used mobile and fixed measurements for recording and analysis of the temperature variations during different weather conditions. One aim of the project was to incorporate the complexity of urban structure and urban heat island effects into the present road surface temperature forecast models. The benefit of this will be to increase the possibilities to issue pre-warnings and effective winter road maintenance operations in urban areas. Within the pilot project, urban heat island intensity effects were analyzed with respect to cause for slipperiness.
