摘要：AbstractThe research aims to establish the correlation of roadway design features to operating speed in the Italian urban environment elaborating multiple-linear models able to predict the observed speed with these design variables as covariates. Furthermore, a cross-country comparison with other models was pursued, establishing their consistency with the Italian dataset through a re-calibration study. The project focused on road segments characterized by dissimilar geometric features. Speed measurements were carried out at each different station per segment under free-flow conditions. Different models were calculated, combining both the complete dataset and disaggregating for the different road typologies.
