EnduRL: Enhancing Safety, Stability, and Efficiency of Mixed Traffic Under Real-World Perturbations Via Reinforcement Learning

2 code implementations21 Nov 2023 Bibek Poudel, Weizi Li, Kevin Heaslip

To address this, we introduce a reinforcement learning based RV that employs a congestion stage classifier to optimize the safety, efficiency, and stability of mixed traffic.

Can ChatGPT Enable ITS? The Case of Mixed Traffic Control via Reinforcement Learning

1 code implementation13 Jun 2023 Michael Villarreal, Bibek Poudel, Weizi Li

However, defining objectives of RL agents in traffic control and management tasks, as well as aligning policies with these goals through an effective formulation of Markov Decision Process (MDP), can be challenging and often require domain experts in both RL and ITS.

Efficient Quality-Diversity Optimization through Diverse Quality Species

1 code implementation14 Apr 2023 Ryan Wickman, Bibek Poudel, Michael Villarreal, Xiaofei Zhang, Weizi Li

This can be rectified by Quality-Diversity (QD) algorithms, where a population of high-quality and diverse solutions to a problem is preferred.

Mixed Traffic Control and Coordination from Pixels

no code implementations17 Feb 2023 Michael Villarreal, Bibek Poudel, Jia Pan, Weizi Li

In certain scenarios, our approach even outperforms using precision observations, e. g., up to 8% increase in average vehicle velocity in the merge environment, despite only using local traffic information as opposed to global traffic information.

Black-box Adversarial Attacks on Network-wide Multi-step Traffic State Prediction Models

1 code implementation17 Oct 2021 Bibek Poudel, Weizi Li

While the prediction accuracy of deep learning models is high, these models' robustness has raised many safety concerns, given that imperceptible perturbations added to input can substantially degrade the model performance.
