Cascading failures and maintenance optimization of urban transportation networks

A convenient urban transportation network facilitates a high-quality life and high-growth economy. Due to cascading failures being ticklish question triggering continuous road congestion, the maintenance plan is momentous restore network. Considering fault edges are removed cars slowly drive out of these ease traffic distribution model proposed analyze process. To resume network, this paper proposes optimization with minimizing time. It recovers from two perspectives: intra-area inter-area model. At last, city in China regarded as case study illuminate feasibility models. The results show that on premise dividing areas, it reasonable adopt for failures. Compared plan, saves more
