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 the lengths of the elements (previous, current and oncoming) are explicitly considered. Furthermore the influence of the presence of accesses is evaluated. The experiments carried out allowed to quantify the influence of previous, current and oncoming elements and features on the operating speed. Outcomes are expected to benefit both researchers and practitioners

Abstract
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 the lengths of the elements (previous, current and oncoming) are explicitly considered. Furthermore the influence of the presence of accesses is evaluated. The experiments carried out allowed to quantify the influence of previous, current and oncoming elements and features on the operating speed.
