Secondary title:	Effects of road axix parameters on road safety
Secondary abstract:	Researches throat the world has shown that two-way rural highways are the most dangerous among the other types of roads. It was identified that the most notable cause for immerging fatal and other crashes are unbalanced and excessive speeds, which occur mainly in the region of the curve. Every combination of horizontal curves has its own unique distribution of real driving speed, which leads in a verity of resulting dynamics effects. To be able to provide adequate safety, road pavement structure must be able to provide the appropriate skid resistance. In the case when friction coefficient is lower than demanded value, dangerous road conditions occur. In the following paper three methods for predicting road safety are presented: models by Lamm, Juvanc and IHSDM. The algorithms of the models were used to make an automated computer program, which is able to calculate the resulting speed profile and the profile of dynamic parameters. Model proposed by Juvanc was further used to show the link between the driving dynamics characteristic (safety measure) and the parameters of road axis. Length of horizontal curve, parameter of transition curve, grade, driveway width and crossfall rate were analyzed.
