This research paper aims to study the effect of tram management on traffic fluidity and its impact on car drivers’ behaviors at junctions crossed by trams. The methodology used in this research is based on a mathematical model and an investigation of car drivers. The first step is to analyze the data of annual travelers’ attendance and assess the number of trams offered and needed in operation to respond adequately to the factual demand. The second step proceeds to show how the previous results of the trams’ fleet influence traffic jams. That is, this step identifies how the number of trams used in operation blocks other motorists and reduces traffic flow capacity at junctions. Finally, the purpose of the questionnaire is to determine car drivers’ opinions of the causes of traffic congestion at junctions and understand how this phenomenon affects their behaviors. The outcomes demonstrate that tram management is ineffective because there is a considerable gap between the annual offered tram fleet and the actual one needed according to the real statistical data. The high number of trams utilized is the leading cause of traffic congestion. Furthermore, this situation disturbs the control of traffic lights at common intersections. Unfortunately, this outcome is the main reason for drivers’ poor behavior, as 75.20% of car drivers are always stressed. These issues have intensified traffic jams in several junctions along the tram line. The article recommends some solutions to improve tram management and traffic fluidity to avoid the substandard behavior of car drivers at junctions.

In recent years, both in Poland and throughout Europe the number of road accidents and the number of people injured and killed in these cases systematically decreases (despite a slight increase in 2011). Despite the general goals of EU transport policy for years 2000-2010 have not been fulfilled (the number of fatalities in road accidents have not been reduced by half in these years) the Commission on Mobility and Transport is continuing its efforts to reduce the number of accidents, which resulted in the EP resolution of 27th August, 2011. Under this policy, the EU Member States are forced to develop and implement appropriate procedures and requirements associated with road safety analysis in the near future. An important obligation have been introduced with the Directive 2008/96/EC, stating the compulsory road safety audits (RSA) should be carried on TEN-T road network. European Parliament also announced extension of this obligation on other public roads in the near future. These aspirations could be supported with modern engineering and research technology. In following article, authors describe the possibilities of using eyetracking technologies in studies over road safety analysis. Therefore, modern eyetracking devices were characterized, with particular emphasis on its possible use in the study of driver's behaviours in road traffic conditions. Also, a brief analysis of the methodology of the eyetracking experiments in traffic conditions and their results was presented, indicating possibilities of carrying RSA using similar equipment. In the last chapter authors, discuss possible use of eyetracking technologies in studies of road safety analysis in the context of the existing law in European Union and each member's law regulation system.
