Traffic Systems Optimization via Multi-Agent Simulation

I'm looking for an expert in multi-agent reinforcement learning and simulation specifically tailored for city-level traffic systems. The main goal of this project is to enhance traffic flow optimization through this simulation.

Key Requirements:
- Proficient in designing simulations with multi-agent reinforcement learning
- Experience and understanding of traffic systems
- Previous work done at city-level simulations
- Capable of demonstrating improvements in traffic flow optimization
