SCENIMINI - Scenario Mining in Traffic Data

SCENIMINI automatically interprets vehicle movement data and processes it in such a way that it can be easily reused in the form of a knowledge base. SCENIMINI thus provides the foundation for the development and validation of automated driving functions, for measures to improve traffic safety, and for research into the behavior of road users.

SCENIMINI (Scenario Mining in Traffic Data) is a research service provided by the German Aerospace Center (DLR) and serves as the technological link between DLR research vehicles, infrastructure-based traffic data collection, and the systematic analysis of traffic.

Traffic data, particularly trajectory data, serves as the starting point for many research projects and scientific inquiries. This data is collected via infrastructure, for example at the AIM research intersection, in the Test Bed Lower Saxony, or through mobile measurement stations. In addition, trajectory data is generated by DLR research vehicles and in simulations.

For various applications, this data - which is often heterogeneous and initially unstructured - must be fused, synchronized, and further processed. This is particularly true for real-world data, where different sensor sources, collection conditions, and data formats must be integrated.

SCENIMINI supports the automated annotation and analysis of trajectory data to extract relevant traffic scenarios. The goal is to build a scenario-based knowledge base in which trajectory data is semantically annotated. This knowledge base serves as the foundation for further analyses, including those related to the development and validation of automated driving functions, the analysis of traffic safety, and the modeling of road user behavior.

Key Features

Scenario-Based Traffic Analysis
SCENIMINI enables the systematic analysis of real and simulated traffic data. Relevant traffic situations are identified from trajectory data, annotated, and made available in a structured format as scenarios.

Data Fusion and Semantic Annotation
SCENIMINI supports the processing of heterogeneous data sources from infrastructure, mobile measurement systems, research vehicles, and simulations. The data is fused, preprocessed, and semantically enriched.

Standardized Scenario Formats
Extracted scenarios can be provided in standardized data formats, specifically ASAM OpenDRIVE® and ASAM OpenSCENARIO® XML. This allows the scenarios to be reused in simulation, analysis, and validation environments.

Open-Source
TASI: A component of SCENIMINI is TASI, an open-source Python library for managing and analyzing traffic data. TASI on GitHub:
https://github.com/DLR-TS/TASI
Datasets: SCENIMINI was used to create and process publicly available datasets https://zenodo.org/records/15754836, https://zenodo.org/records/18540070
