Here we study traffic networks with multiple origin-destination pairs, relaxing the simplifying assumption of agents having complete knowledge of the network structure. We identify a ubiquitous class of networks, i.e., rings, for which we can safely increase the agents\u2019 knowledge without affecting their own overall performance - known as immunity to Informational Braess\u2019 Paradox - closing a gap in the literature. By extension of this performance measure to include the welfare of all agents, i.e., minimisation of social cost, we show that IBP is a widespread phenomenon and no network is immune to it.<\/jats:p>","DOI":"10.24963\/ijcai.2019\/80","type":"proceedings-article","created":{"date-parts":[[2019,7,28]],"date-time":"2019-07-28T03:46:05Z","timestamp":1564285565000},"page":"565-571","source":"Crossref","is-referenced-by-count":2,"title":["Multi-Population Congestion Games With Incomplete Information"],"prefix":"10.24963","author":[{"given":"Charlotte","family":"Roman","sequence":"first","affiliation":[{"name":"Department of Mathematics, University of Warwick"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Paolo","family":"Turrini","sequence":"additional","affiliation":[{"name":"Department of Computer Science, University of Warwick"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"10584","event":{"number":"28","sponsor":["International Joint Conferences on Artificial Intelligence Organization (IJCAI)"],"acronym":"IJCAI-2019","name":"Twenty-Eighth International Joint Conference on Artificial Intelligence {IJCAI-19}","start":{"date-parts":[[2019,8,10]]},"theme":"Artificial Intelligence","location":"Macao, China","end":{"date-parts":[[2019,8,16]]}},"container-title":["Proceedings of the Twenty-Eighth International Joint Conference on Artificial Intelligence"],"original-title":[],"deposited":{"date-parts":[[2019,7,28]],"date-time":"2019-07-28T03:46:38Z","timestamp":1564285598000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.ijcai.org\/proceedings\/2019\/80"}},"subtitle":[],"proceedings-subject":"Artificial Intelligence Research Articles","short-title":[],"issued":{"date-parts":[[2019,8]]},"references-count":0,"URL":"https:\/\/doi.org\/10.24963\/ijcai.2019\/80","relation":{},"subject":[],"published":{"date-parts":[[2019,8]]}}}
