CDSubject(s): Online resources: Bibl.nr: VTI 2011.0119 RefLocation: Plac: Expeditionen, referensmärkta samlingsverkNotes: Ingår i VTI 2011.0119 Abstract: The main objective of IRWIN is to develop an improved winter road index capable of assessing the implications of climate change in various weather parameters and also related road maintenance actions. Climate change scenarios have so far been calculated based on ordinary meteorological data, which have large limitations in respect to resolution. The idea of IRWIN is to combine the best traditionally made climate scenarios with the much more accurate spatial data from field stations in the Road Weather Information systems (RWIS) installed in most northern hemisphere countries. This Final Report presents first briefly the results of the two inception reports: state-of-the-art of climate models and winter index formulation, the data collection and database formation phase of the project. The objective was to develop a novel database of possible future road condition scenarios by combining archived historical RWIS data with widely accepted climate change scenarios. Observations from the Swedish and Finnish RWIS stations were collected from national Road Administrations from as long time span as has been archived with homogeneous contents and quality. The target was to get 10 years of observations of air and surface road temperature, moisture, wind speed, rainfall amount and precipitation type.Current library | Status | |
