The speed reductions can affect to the safety of the road. The Interactive Highway Safety Design Model (IHSDM) Design Consistency Module presents an analysis of the relation between the speed reduction and the accidents for horizontal curves on American two-lane rural highways. In this paper a similar study is performed for Spanish two-lane rural highways. A model for predicting accidents through regression analysis is presented using speed reduction between successive tangents and horizontal curves and between successive curves. Significant parameters related to exposure and geometry as explanatory variables are used.
