One of the factors directly influencing accidents is the road and its environment. The specialists estimated that this factor accounts for 30 percent of all casual factors. Investment in road infrastructure is cost consuming; it looks rather reasonable to invest in black spots. The occasional changes of road itinerary or identification in the registration system makes precise location of accidents is very difficult. This is one of the reasons to start using a Geographical Information System and global coordinates. The background is a very rich source of information in relation to identification of places of potential danger, such as places located near water reservoirs or sections of roads in the forest, where the operation during the day and night in the winter makes the pavements icy. Because of this the GDPR decided to conduct the pilot study in the field of location of black spots using the GIS technique. The three main roads in Poland were in the scope of the study. An example of the result of the study is presented in the following picture that is part of the printout of the numerical map. The next step will be to improve methods of locating the accident. The Global Positioning System will be used. The paper consists of this abstract.
