Our scenarios are used to analyze the interactions between vehicles, their environment and other road users in order to develop and test driver assistance systems and connected and automated driving functions.
The TASC dataset is based on real accident data, which is converted into simulation files using specially developed procedures and scientific methods.
On the one hand, it contains several thousand basic simulation files. These represent real accident data from Saxony, which is based on data from police accident surveys.
In addition, scientifically sound methods and variation approaches based on GIDAS data are used to create further variation simulation files from these basic data sets.
Since 2022, not only accident data has been hosted on the TASC platform, but also data from traffic observations. This data collection approach makes it possible to record tens of thousands of real-life traffic scenarios within a short period of time, with the subsequent criticality assessment allowing a separation into normal, critical and highly critical scenarios.
The dashboard developed in 2021 allows authorized users to pre-select simulation files and perform user-specific accident analyses within the entire TASC dataset. The following figure shows some example diagrams of the dashboard.
Selected statistics are displayed in the dashboard (accident categories, constellations, types, day and time distribution, location of accidents).

In order to further advance the development and validation of advanced driver assistance systems (ADAS) and highly automated driving functions (AD) in simulation in the future, VUFO is currently working on the transfer of real, concrete accident scenarios into the standardized formats OpenDRIVE 1.6 and OpenSCENARIO 1.0. Both formats are technology and manufacturer-independent and are based on the syntax of the Extensible Markup Language – XML. Our work thus creates a way to integrate real accident scenarios into simulators or simulation solutions in the future.
OpenDRIVE is used to describe the road network and its surroundings. Information on road geometry, lanes, markings and objects (e.g. buildings, parked cars, traffic signs) is stored in the file.
OpenSCENARIO is used to describe the dynamic behavior of road users. It can be used to describe maneuvers based on driver reactions and trajectories and to store information about the participants (e.g. type and dimensions).
VUFO has automatically transferred the first accident scenarios from the GIDAS PCM to OpenDRIVE 1.6 and OpenSCENARIO 1.0. For the time being, these are scenarios with simple road geometries (e.g. accident scenes on straights or in bends) and few lanes. An extension to more complex accident scenes with junctions and intersections is planned for the future.
We are also working on the PCM format. PCM stands for Pre-Crash Matrix and is a specified format that can be used to describe the phase of a traffic accident before the first collision (the so-called pre-crash phase). The GIDAS PCM can be used to display and evaluate the parties involved, their dynamics and the environment.

PCM is a specified format that can be used to describe the phase of a traffic accident before the first collision (the so-called pre-crash phase). The GIDAS PCM can be used to display and evaluate the parties involved, their dynamics and the environment.
The PCM was originally developed as an internal format by VUFO in 2011 to provide project partners with pre-crash data for accidents investigated as part of the German In-Depth Accident Study (GIDAS). Version 5.0 of the current format has been defined and published since 2019. Since then, it can be used for any accident or scenario database and is freely accessible.
The specification contains the structure, the variables and the associated descriptions of the PCM format. Properties and libraries have so far been prepared for the German transport infrastructure. Other country-specific infrastructure can be stored and used in additional tables.
The current GIDAS-PCM format specification, including the available libraries, as well as an example scenario are freely available for download.
