BBD-V - Ground Motion Service for the transport sector

Country / Region: Deutschland

Begin of project: November 1, 2024

End of project: October 31, 2027

Status of project: March 14, 2025

Ground motions caused by geogenic and anthropogenic causes can damage traffic infrastructures and, in the worst case, endanger people. Even small ground motions of this kind can significantly impede traffic. Monitoring in the transport sector is currently mainly carried out using terrestrial measurement techniques for selected areas and is time-consuming and cost-intensive. Earth observation using satellite-based interferometric SAR (InSAR), on the other hand, makes it possible to detect ground motions with an precision of a few mm per year for entire nations or continents. This was made possible by the Copernicus Programm of the EU and the Synthetic Aperture Radar (SAR) satellite mission Sentinel-1 of the European Space Agency (ESA).

When developing the services, a particular focus will be placed on integrating the end users from the transport sector and taking their needs into account in order to make the BBD-V easy to integrate into practical work. In addition, the functions developed and their results are to be verified on the basis of processes and events observed in situ in order to ensure that they are resilient for real-life operation and the practical planning and implementation of monitoring and inspections.

Project aims and Realisation

This project aims to develop and establish a ground motion service for the entire German transport sector (BBD-V) and thus meet the demand for ground motion data in the transport sector. The functionalities of the service are divided into two levels:

• Basic function based on the existing products of the German Ground Motion Service of the BGR (BBD) with improved features for transport infrastructure (e.g. availability of data points and analyses of processes relevant to transport)
• Extension functions that are adapted with special analysis steps for the detailed and case-specific application of transport infrastructure monitoring.
  

Project implementation

All tasks are implemented in the following nine work packages:

• WP 1: User requirements and user stories
• WP 2: Optimization of the BBD for traffic applications
• WP 3: Method development for the detection of processes and motion patterns relevant to transport infrastructure
  
• WP 4: Development of a method for the consideration of temporal scatterers in multi-temporal InSAR time series for traffic infrastructure monitoring
  
• WP 5: Development of a procedure for updating multi-temporal InSAR time series
  
• WP 6: Validation
  
• WP 7: Development of visualization concept and quality specifications
  
• WP 8: Implementation of the web application
  

• WP 9: Project organization and dissemination
  

  
  

Consortium partners

The BBD-V project is being realised by a research consortium. The Federal Highway and Transport Research Institute Bergisch-Gladbach,is responsible for project coordination.

In addition to the Federal Institute for Geosciences and Natural Resources, Hanover, the institutions involved in the project are

• German Center for Rail Transport Research
• Federal Institute of Hydrology, Koblenz
