Purpose. The most pressing problem facing the rail traffic safety experts is an accident rate at the railway level crossings. The purpose is to investigate the circumstances, which affect traffic safety at the level crossings, and to offer effective tools for experts to improve the safety the problems of these dangerous spaces of railway infrastructure. Methodology. This paper observes the logistic regression as a method to estimate the accident rate at level crossings in Lithuania. The authors have studied and evaluated the key factors affecting the safety of railway crossings. These factors are the intensity of trains and road transport means through the railway level crossing, the visibility of the approaching train from both sides of the traffic, the maximum permissible speed of the trains, the number of tracks (single track, double track, and multi-track), the level of installed alarm and automatic equipment, a density of population in this area, etc. Finally, only the factors, which might be described by mathematical expressions (numbers), were identified. Findings. By using logistic regression method, it was found that the most determinant factors at level crossings are the maximum speed of trains, poor visibility crossing (less than 1,000 m), intensity of the road traffic at crossings, and inappropriate implementation of roads crossing the rails. Based on the study results, the conclusions and recommendations were formulated which primary measures to prevent accidents at level crossing and on what level crossing should be taken urgently. Originality.Revealed trends and major causes of accidents at railway crossings of Lithuania for 2004-2011 year. The necessity of implementation of progressive technical measures for the prevention accidents on railway level crossing is proved. Practical value. About 50% of Lithuanian railway crossings do not meet the requirements of the level crossing legislation. This parameter is one of the key risk factors for traffic safety at level crossings. In order to eliminate the effect on accident due to poor visibility of moving train, it is proposed to use the "speed bumps". Question of the elimination of one level crossing is becoming more and more important due to the increased volume of traffic on the roads and railways, growing the speed of trains and the implementation of important large-scale road and rail projects.
