To satisfy these requirements, this work proposes effective, scalable, multi-input and multi-output, and congestion prevention-enabled intersection management system utilizing a software-defined control interface that not only regularly monitors the traffic to prevent congestion for minimizing queue length and waiting time but also offers a computationally efficient solution in real-time. For effective intersection management, a modified linear-quadratic regulator, i.e., Quantized Linear Quadratic Regulator (QLQR), is designed along with Software-defined Networking (SDN)-enabled control interface to maximize throughput and vehicles speed and minimize queue length and waiting time at the intersection. Experimental results prove that the proposed SDN-QLQR improves the comparative performance in the interval of 24.94%\u201349.07%, 35.78%\u201368.86%, 36.67%\u201359.08%, and 29.94%\u201357.87% for various performance metrics, i.e., average queue length, average waiting time, throughput, and average speed, respectively.<\/jats:p>","DOI":"10.1145\/3641104","type":"journal-article","created":{"date-parts":[[2024,1,16]],"date-time":"2024-01-16T12:01:49Z","timestamp":1705406509000},"page":"1-25","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":9,"title":["SDN-enabled Quantized LQR for Smart Traffic Light Controller to Optimize Congestion"],"prefix":"10.1145","volume":"24","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2907-3305","authenticated-orcid":false,"given":"Anuj","family":"Sachan","sequence":"first","affiliation":[{"name":"Indian Institute of Technology-Roorkee, Roorkee, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0516-1095","authenticated-orcid":false,"given":"Neetesh","family":"Kumar","sequence":"additional","affiliation":[{"name":"Indian Institute of Technology-Roorkee, Roorkee, India"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"320","published-online":{"date-parts":[[2024,2,22]]},"reference":[{"key":"e_1_3_1_2_2","doi-asserted-by":"publisher","DOI":"10.1109\/TITS.2020.3038250"},{"key":"e_1_3_1_3_2","article-title":"Measuring traffic congestion\u2014A critical review","author":"Aftabuzzaman Md","year":"2007","unstructured":"Md Aftabuzzaman. 2007.
