Investigation of the Spatio-Temporal Impact of Traffic Accidents

Introduction and goal of this thesis

Traffic accidents play an important role in our lives in terms of safety and security, especially for people. Everyone is affected by traffic accidents either directly (involved) or indirectly (consequences). Consequences such as traffic jams or road (lane) closures not only disrupt delivery and rush hour traffic, but can also lead to additional accidents. In addition, different types of traffic accidents can have different consequences. For example, an impact could be found in a reduction of the average travel speed on the road or on nearby roads in the time after an accident has occurred.

The goal of this thesis is to investigate the impact of traffic accidents based on vehicle trajectories. Therefore, accident and trajectory data need to be linked and the spatial and temporal impact needs to be analyzed.
