📌 Project Overview
- Context: Master’s Thesis at TUM Asia & R&D Project with IABG Industrieanlagen-Betriebsgesellschaft mbH
- Location: Mobility Innovation Campus (MIC), Munich, Germany
- Keywords: Autonomous Vehicles (AVs), V2X Communication, SUMO, TraCI, Reinforcement Learning (DQN), Adaptive Signal Control.
🚦 Core Innovation & Methodology
- Bidirectional Coordination Framework:
- Integrated connected autonomous vehicle trajectories with roadside unit (RSU) sensors.
- Enabled real-time bidirectional negotiation between oncoming AVs and traffic signal controllers.
- SUMO/TraCI Microscopic Simulation:
- Built high-fidelity microscopic simulation environments mirroring the MIC test site geometry and real-world V2X message flows (SPaT, MAPEM, CAM/BSM).
- Automated co-simulation pipelines using Python and TraCI APIs.
- DQN-Based Adaptive Signal Control:
- Formulated signal phase selection as a Markov Decision Process (MDP).
- Designed reward functions balancing overall intersection throughput, individual vehicle delay, and queue length.
- Validated robustness under varying traffic demands (peak/off-peak) and mixed V2X penetration rates (0% to 100%).
