A postdoctoral fellowship is available at the University of Toronto, focusing on world models and reinforcement learning (RL) for traffic signal control. This opportunity is ideal for candidates with a strong publication record in top-tier machine learning and RL venues, and with experience in traffic systems. The research will involve developing and applying advanced AI and machine learning techniques to optimize traffic control, with the goal of improving urban mobility and efficiency. Responsibilities include publishing research in leading venues, producing high-quality code for research partners, and providing research supervision. The successful candidate will join a vibrant research environment at the University of Toronto, collaborating with experts in machine learning, artificial intelligence, and traffic systems. The position is supervised by Professor Scott Sanner, a recognized leader in the field. The application deadline is early February 2026, with the fellowship expected to commence no later than September 2026. To apply, candidates should email Professor Sanner with a CV, a link to their public GitHub account, and a brief statement of interest. While the post does not specify funding details, it is a postdoctoral fellowship at a leading Canadian institution, offering an excellent platform for research and career development in AI, RL, and traffic control systems. Keywords: reinforcement learning, world models, traffic signal control, machine learning, artificial intelligence, postdoctoral fellowship, University of Toronto.

In this paper, we examine the practical problem of minimizing the delay in traffic networks that are controlled at each intersection independently, without a centralized supervisory computer and with limited communication bandwidth. We find that existing learning algorithms have lackluster performance or are too computationally complex to be implemented in the field. Instead, we introduce a simple yet efficient and effective approach using multi-agent reinforcement learning (MARL) that applies the Deep Q-Network (DQN) learning algorithm in a fully decentralized setting. First, we decouple the DQN into per-intersection Q-networks and then transmit the output of each Q-network’s hidden layer to its intersection neighbors. We show that our method is computationally efficient compared with other MARL methods, with minimal additional overhead compared with a naive isolated learning approach with no communication. This property enables our method to be implemented in real-world scenarios with less computation power. Finally, we conduct experiments for both synthetic and real-world scenarios and show that our method achieves better performance in minimizing intersection delay than other methods.
