The objective of this paper is to consider a possibility to use the geometric design consistency analysis as a method to evaluate safety of roads on the Serbian road network. Lack of maintenance due to the multiyear economic crisis resulted in a poor condition of over 50 per cent arterial and regional road network with modern pavement. Furthermore, the safety of Serbian roads, according to the number of accidents and the kilometers traveled on the entire road network, is two times lower than the road safety in Western European countries. Key activities of the Serbian road industry in the years to come will be oriented toward rehabilitation of the road network, improvement of their safety, and compliance with environmental protection requirements. Serbian road design regulations are almost 25 years old. In spite of the fact, the design practice observes the state-of-the-art road design methods, including analysis of design speed profile and required sight distance profile as basic criteria in the design of some road elements. Thus conceived design process may be satisfactory for the design of new road sections. However, for evaluation of safety of the existing road sections it is necessary to define a specific methodology that would be based mostly on the already accepted design practice. The paper considers use of speed profile and available sight distance profile, which are accepted in the design practice, as basic indicators of the geometric design consistency of road elements. Samples given in the paper show comparison of the presented method with the practice applied in other countries. The presented method, as a theoretical model, represents a basis for any future research. Further research would call for field measurements and statistical data analysis in order to verify the hypotheses presented in the model and to calibrate the model according to the conditions on the Serbian road network (A).
