Modeling operating speed of two lane rural road

This paper focuses on the analysis of the influence of road alignment on operating speed in two-lane rural roads.The authors propose a new operating speed model in which the geometric features of an alignment and thelengths of the elements (previous, current and oncoming) are explicitly considered. Furthermore the influence ofthe presence of accesses is evaluated.The experiments carried out allowed to quantify the influence of previous, current and oncoming elements andfeatures on the operating speed.Outcomes are expected to benefit both researchers and practitioners
