Spatial Risk Assessment Model for the Transport of Dangerous Goods by Road

In today's globalized society, the transportation of hazardous goods plays an important role in economic processes. With this growing trend, the transportation of hazardous materials brings a new challenge in terms of responsibility for ensuring safety and minimizing risks during transportation. The theoretical part of this scientific article describes the model by Ebrahimi and Tadic, which examines accident rates on a given edge of a graph, and how this research further develops by adding necessary variables. In the practical part, fleet data obtained from the real operations of transportation companies will be presented, providing a comprehensive overview of the movements of transport units. These data are analyzed in the study in relation to accidents involving transport units with a weight exceeding 7.5 tons in the Czech Republic. This data allows for the investigation not only of the probability of accidents involving units with a weight over 7.5 tons but also the impact and severity of these accidents. Additionally, a modified D-R routing model will be introduced.
