Post-accident Analysis of Digital Sources for Traffic Accidents

This paper describes sources of digital information which can be used for traffic analysis, and in particular post-accident analysis. We discuss how we can use this information to automatically find likely causes for traffic accidents and create a system which makes a simple report of an accident. With the Veins simulator we generate data of a head-tail collision and normal traffic situation in a vehicular ad-hoc network. This data is used as input to validate the system. It shows that the system can recognize when a collision between two vehicles occurs and provide a report about the behavior of the vehicles prior to the accident.
