Projects
Jena5G
Funding body: Federal Ministry for Digital and Transport (BMDV)
Project duration: 2021 – 2024
Short description: Within the Jena5G project, a central, phase-oriented and multimodal traffic signal control system based on AI-supported methods was developed, tested and partially trialed in the field for an urban network.
Project website: Jena5G
Contribution & Role
- Work package lead and project engineer within the work package “Cooperative traffic signal control (kLSA)”
- Design and specification of the system architecture, use cases, interfaces and data models in coordination with international project partners
- Setup, calibration and application of a microscopic simulation model (PTV Vissim) for training, testing and evaluation of the AI agents
- Development and qualification of a universal traffic signal field device supply for implementing AI-based control commands and technical supervision of the transfer of research prototypes into a production-ready system architecture

QLSA Dresden – Traffic Control Optimization East-West-Connection
Funding body: European Regional Development Fund (ERDF)
Project duration: 2018 – 2023
Short description: In the project "Optimization of traffic control on the East-West connection and the City Ring in the state capital Dresden", measures to reduce waiting times and improve the punctuality of public transport were implemented. A core component was the introduction of a multi-objective traffic signal control (QLSA) at 35 intersections, 20 of which featured specific public transport priority, complemented by an integration with the vehicle-side assistance system COSEL to improve traffic quality and connection stability.
Project description: DVB AG
Contribution & Role
- Further development and implementation of the central QLSA control algorithms
- Implementation and parameterization of the central QLSA control logic for specific intersections within the Dresden project area
- Technical representation of the professorship as the responsible system developer within the consortium
- Conception, technical lead and implementation of a Vissim-COM integration of the QLSA system for the evaluation of different control strategies

ABSOLUT I
Funding body: Federal Ministry for Digital and Transport (BMDV)
Project duration: 2019 – 2022
Short description: ABSOLUT (Automatic Bus System On-Line Urban Transport) was a lighthouse project for autonomous driving in public transport in Leipzig. The overall system comprised the networking of autonomous vehicles with traffic signal systems using C-ITS technologies, a traffic management center demonstration, a customer-oriented app, and multimodal integration into the existing public transport network in order to demonstrate technical feasibility and user acceptance.

Contribution & Role
- Work package lead and project engineer within work package 5 “Infrastructure”
- Specification, development, implementation and qualification of infrastructure components as an integral part of the overall system
- Technical supervision and review of the redesign of 12 traffic signal controllers, including technical equipment with C-ITS components
- Further development and implementation of central control components, as well as their evaluation and fine-tuning within the integrated system
