The paper is focused on a two lane rural road (named S.S. n. 125) which are designed in order to the new Italian highway geometric design guidelines (Ministry of Infrastructures and Transports, “Functional and geometrical guidelines for road construction”, M.D. November 5th, 2001). The national and international models, in order to link driver behavior and road features, are applied on this road. In fact, we know precisely the geometric and design features of the S.S. n. 125; besides this road has a varied alignment, that gathers different types of road environment. It allows to test out several models. In the beginning of the paper, we sum up the most important national and international models, that enable to calculate operating speed and/or speed environment. The models, whose the hypothesis are in the local road, are tested in the S.S. n. 125. We checked more models, in relationship to different road sections, which are linked to other hypothesis. Next experimental surveys allowed to corroborate or to deny the analytical models. The target of this research work consists in estimating an analytical model that permits to calculate operating speed or speed environment, for example, as a function of the available sight distance.
