Accidents prediction model based on speed reduction on spanish two-lane rural highways Oña López, Juan José De Garach, Laura Road safety Speed reduction Horizontal curves Consistency Two-lane rural highways Poisson distribution Spain 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. 2013-04-10T06:55:08Z 2013-04-10T06:55:08Z 2012-10-03 info:eu-repo/semantics/article de Oña, J.; Garach, L.
