It is well acknowledged that congestion results in increased travel time, fuel consumption\/emission, and reduced traffic throughput on roads. Furthermore, causes of congestion such as lane closures and cyber infrastructure failures present various challenges to drivers in reaching their destinations. Strategies such as high occupancy vehicle lanes and fast-track routes have been implemented nationwide to improve the performance of road networks. However, the advent of CAVs has opened up new avenues for research to explore their positive effects on traffic and their contribution to improved network performance. Thus, we developed and validated an agent-based simulation model to capture the interactions of CAVs, regular vehicles, traffic lights, and the road network under both physical and cyber disruption scenarios. Experiments were conducted in two different study sites\u2014highway and urban road networks in the State of Oklahoma. The results indicated that introducing CAVs to the selected road networks improved travel times under different magnitudes of random lane closures and communication failures. Despite a 30% communication failure and 20% random lane closures, CAVs outperformed non-CAVs with better mean travel times. Redundancy mechanisms also allowed CAVs to manage congestion effectively, although CAVs with functional communication still exhibited 5% better performance than those relying solely on redundancy mechanisms.<\/jats:p>","DOI":"10.1177\/00375497241308575","type":"journal-article","created":{"date-parts":[[2025,1,29]],"date-time":"2025-01-29T13:24:42Z","timestamp":1738157082000},"page":"825-844","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":2,"title":["Resilience of connected and autonomous vehicles to cyber\u2013physical disruptions"],"prefix":"10.1177","volume":"101","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6079-5656","authenticated-orcid":false,"given":"Pavithra","family":"Sripathanallur Murali","sequence":"first","affiliation":[{"name":"Department of Systems Engineering and Operations Research, George Mason University, USA"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1587-0506","authenticated-orcid":false,"given":"Shima","family":"Mohebbi","sequence":"additional","affiliation":[{"name":"Department of Systems Engineering and Operations Research, George Mason University, USA"}]},{"given":"Musharraf","family":"Zaman","sequence":"additional","affiliation":[{"name":"School of Civil Engineering and Environmental Science, The University of Oklahoma, USA"}]}],"member":"179","published-online":{"date-parts":[[2025,1,27]]},"reference":[{"key":"e_1_3_3_2_2","doi-asserted-by":"publisher","DOI":"10.1007\/978-981-15-8670-5_11"},{"key":"e_1_3_3_3_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.tra.2016.10.013"},{"key":"e_1_3_3_4_2","unstructured":"Bartlett JS.
