Interpretable Intersection Control by Reinforcement Learning Agent With Linear Function Approximator

open access: yesIET Intelligent Transport Systems, Volume 19, Issue 1, January/December 2025.
In this work, the use of the linear function approximator (FA) for a value‐based reinforcement learning (RL) agent in traffic signal control problems is investigated along with the least‐squares Q‐learning method, abbreviated as LSTDQ. The motivation for using the linear FA is the interpretability property of the controller, which is crucial for RL ...
