Description of the research topic:
a) Background:
Road transport system is getting increasingly interconnected, with subsystems (e.g.
vehicle, infrastructure, communication network) communicating with each other. In addition, we are witnessing a modal shift, with novel forms of micromobility gaining ground alongside car transport. An important element in the design and management of the transport system is to simulate it as accurately as possible, with real-time simulation (digital twin) playing an increasingly important role. Traditionally, simulation programmes have focused on only one isolated sub-system (e.g., vehicle simulation, traffic simulation). However, as the transport system becomes more complex, it is essential to connect these simulators to efficiently model new modalities, running in real time.
b) Goal of research:
The aim of the research is to develop a simulation ecosystem that can integrate the different subsystems of road transport. In this context, it is of particular importance to find the optimal trade-off between accuracy, simulation size and frequency. The aim is to model the largest possible transport system with minimal computational resources with appropriate accuracy to ensure realism (e.g., by approximating a high-fidelity simulator with a neural network, or by running agents in parallel). This requires scientific progress in simulation techniques and parallel computation.
c) Main tasks of research:
• Literature review
• Architecture design of the transport system simulation ecosystem
• Development of models of different accuracy for each component
• Optimisation of the simulation environment
• Design and testing of digital twin
• Dissertation writing
e) Minimum expected scientific results:
• Three papers in international SCI indexed journals with impact factor.
• Three articles in international conference papers.
