Joined Optimization of Traffic Signaling and Vehicle Speed Advisory in V2I-Enabled Traffic

Supervisor: Johannes Busch

With emerging Vehicle-to-Infrastructure (V2I) communication technologies, such as IEEE 802.11p or 5G, arises the opportunity for an intelligent traffic infrastructure that is able to quickly adapt to the current state of the traffic system.Through the exchange of information between individual vehicles and the traffic infrastructure, traffic signaling could be tailored to individual vehicles. Furthermore the traffic infrastructure could advise drivers on appropriate driving velocities. These measures could improve traffic flow and therefore mitigate environmental and economic repercussions of traffic systems. However, the optimization of large distributed systems under the availability of intricate knowledge about the system state is not trivial and novel control paradigms need to be explored. A promising candidate could be Deep Reinforcement Learning (DRL), which has shown to be able to solve many intricate control problems by learning from interaction and has also successfully been applied to traffic control systems.

In this Diploma/Master thesis, a joint optimization of traffic signaling and speed advisory with DRL should be explored. Subtasks include:

  • A literature review of the current state of the art of intelligent traffic control, V2I, and DRL.
  • An extension of an existing traffic simulator to enable the joint control of traffic signaling and speed advisory, under the knowledge of the current state of the traffic system.
  • The optimization of the developed simulation with an appropriate DRL algorithm. Preferably, the proposed solution should be scalable to large infrastructures.
  • An experimental review of the benefits of the developed intelligent V2I-enabled traffic control system. Various experimental setups could be explored here. For instance, the scalability to large traffic systems or the influence of different penetration rates of V2I-enabled vehicles could be two particularly interesting paths to explore.

Prospective students should have previous knowledge in the Python programming language and a keen interest and previous experience in Machine Learning (preferably DRL).
