Review for NeurIPS paper: EcoLight: Intersection Control in Developing Regions Under Extreme Budget and Network Constraints

My main concern is that the paper, while being practical and useful in real-world, has limited technical contributions from an AI perspective. I do appreciate that the authors are trying to make the writing clear and simple, it somehow appears to be more like a collection of engineering efforts to make the system work. The paper is also written in a way that looks like a "technical report" rather than a machine learning type of paper. For example the Markov Decision Process underlying the problem is never formally defined, especially state transitions. It will be helpful to write down these definitions.
