Popis: This paper develops a weather traffic model and verifies its validity through temporal transferability within the context of the Alberta highway network. This research used traffic data and weather data collected at four weigh-in-motion (WIM) sites and weather stations for five years to develop models for two-vehicle classes. We collected an additional year of traffic data from the exact four WIM locations to conduct a temporal transferability test. We evaluated the estimation accuracy resulting from the temporal transferability by measuring the value of R2 and the magnitude of five error measures. All in all, the developed models were transferred successfully to a different year. The study results reveal that different structural types of models could be better suitable for each vehicle type at other road functions.
