The absence of road network connectivity by flooding, accident, strategic terrorist attack and traffic jam critically and strongly affects the operation of the entire road network [1]. Using a representative three km radius OSM sample data of Addis Abeba‟s city road network and by measuring the giant component size and diameter change caused by both strategic and random node removal, we assessed the robustness of the network. By simultaneously analyzing the robustness result with global efficiency measure, as an availability measure of the route, we finally assessed the resilience of the network. Our result shows that from giant component size measure, the road network was robust from randomly removing 24% pc value of nodes than strategically removing 4% pc value of nodes. The diameter measure increases from 39 to 51 paths and from 39 to 43 paths against random and strategic node removal respectively. From diameter measure, we conclude that a decreasing diameter measure in response to BC based strategic node removal does not always show a robust network. Rather, the physical structural connectivity determines the robustness measure. In conclusion, greater than 88% of the network was vulnerable for both strategic and random node removal and were not able to be robust and resilient as well. Thus, this finding gives an ample understanding of the cities road network robustness and resilience. Therefore, city planners and administrators can infer about the need of the cities road networks re-design and expansion activities. Additionally, this study helps them to see the city road network‟s vulnerability against betweenness centrality based strategic attack than randomly attacking the road network and this later helps to identify points of BC measures.Verstegen, JudithCasteleyn, SvenHenriques, Roberto André PereiraMuñoz, AndrésRUNGelaye, Tamene Sinishaw2019-04-26T16:09:23Z2019-02-052019-02-05T00:00:00Zinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisapplication/pdfhttp://hdl.handle.net/10362/67709TID:202228304enginfo:eu-repo/semantics/openAccessreponame:Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos)instname:Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãoinstacron:RCAAP2024-03-11T04:31:59Zoai:run.unl.pt:10362/67709Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireopendoar:71602024-03-20T03:34:39.253994Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse
