Visual Analytics of Forest and other Roads Density

This paper compares the indicators of spatial development for the road network of Croatia towards chosen countries in Europe and on a county level in Croatia. It also shows the number of traffic accidents per counties and links it with indicators of spatial development. The paper presents the results of the research of spatial distribution of traffic accidents in Croatia by counties. An example of a hazardous site identification on the A6 motorway is provided by the accident data report. All the comparisons and analyzes are presented graphically in the form of charts and cartography-related views in the MapViewer 7 program. From the results it can be seen that there are significant differences between the counties and it is often the case that similar values for the counties derived from similar level of development and similar number of population. From the results it is concluded that the number of traffic accidents is more dependent on the population than the length of the road network in relation to the surface of the county. To invest in remediation of hazardous sites, it is necessary to consider more factors than repeated traffic accidents.
