The Analysis of Traffic Accident Quantity on the Roads of Central Bohemia

The aim of my diploma thesis is the analysis of traffic accident quantity on roads (highways and motorways) of Central Bohemia. My personal contribution to this topic is the particular analysis of accident frequency within Central Bohemia between 1994 and 2007. Nobody has dealt with such an analysis in frame of this region until the present. In the theoretical part of the thesis, basic definitions are expounded from the theory of traffic accident frequency and the partition of traffic accidents according to different criteria, and the classification of roads. There is a situation described in Central Bohemia for each type of classification for mentioned years. The practical part of the thesis is divided into three sections, which analyze problems from different points of view. In the first part, there are detected reciprocal relations between basic indicators of traffic accident frequency in the particular districts of Central Bohemia. The next part targets the analysis of time series of causes and results of traffic accidents within this region, in particular months of mentioned years. The aim of this part is to describe the trend of time series by acceptable methods and to estimate their supposed development in the following 12 months. In the third and final part of the thesis, the analysis of less commonly considered causes of traffic accidents are performed, as is directional conditions, status of road surface, visibility, weather conditions and transversal setting of communication. The target of this final part is to verify whether these factors significantly influence the number of traffic accidents on different types of roads
