Fig. 1From: Modeling hourly weather-related road traffic variations for different vehicle types in GermanyProbability density functions of meteorological variables used in the models selection process. The thick black line indicates the average probability density at all traffic stations. The grey shaded area covers the range between the 0.1 and 0.9 quantile of probability densities at all traffic stations and indicates the variability between the different stationsBack to article page
