Large-Scale Mobility Data Analytics

Large-Scale Mobility Data Analytics

Ongoing digitalization generates a new wealth of large-scale mobility data. This provides unprecedented opportunities for analyzing and predicting mobility information, but also poses new challenges which have to be overcome: the spatio-temporal dependencies in movement data require new, highly specialized methods in order to allow for efficient processing, analysis and storage.

Established solutions like Apache Hadoop excel at handling large volumes of data, and spatial data support is provided by extensions such as GeoSpark or GeoMesa. However, movement data combine temporal and spatial aspects and are not well supported by existing tools. Implementations of such complex analyses are being developed in the data science community, but they are usually confined to comparatively small datasets. We fill this gap and integrate advanced spatio-temporal data analytics techniques into distributed data management and processing landscapes, thus offering a solution for efficiently processing large-scale movement data.

 

 

We provide a one-stop shop for efficient knowledge extraction from large-scale spatiotemporal mobility & traffic data.

Explorative Data Analysis

We assess data quality, investigate the potential for knowledge extraction, and find and handle data gaps and inconsistencies.

We explore the potential of your mobility datasets and unveil possible pitfalls prior to advanced data-driven analysis.

Machine Learning and Algorithm Development

We apply classical machine learning and deep learning techniques and develop novel customized algorithms for movement data. To ensure quality and performance, we thoroughly validate the knowledge extraction algorithms and identify solutions for distributed computing.

We efficiently capture and exploit the structure inherent in your mobility datasets with scientifically and technically proven machine learning approaches for knowledge extraction.

Professional Software and System Engineering

We develop and integrate software modules. For best performance, we optimize algorithm runtimes and design distributed IT infrastructures (including cloud computing).

Our software for knowledge extraction is well-designed and implemented and may be readily integrated with your existing IT infrastructure.
