Complex disaster response framework to reduce urban disaster vulnerability

Abstract

Cities are vulnerable to a range of disasters that can occur simultaneously due to their complexity. Therefore, an effective disaster response plan is needed to reduce the disaster vulnerability of cities. In particular, evacuation route management is important for reducing the losses from a disaster. Efficient disaster response can be realized by searching for suitable evacuation routes and effective road network management. In this paper, we propose a disaster response framework based on a multilayered road network structure and evacuation routes based on our road network. The suggested road structure consists of three layers for the effective management of the network. An A* algorithm-based search for multiple evacuation routes under different conditions in response to an individual disaster on the configured road map provides a safe route for evacuees. As a result, the damage caused by disasters in urban areas can be ameliorated.

Book review: The Urban Rehabilitation of Post-Disaster Scapes

“…Urbanscape alteration allows disasters to have a more serious impact, such as the organisation and design of structures within open space causing direct landslides; rapid and unplanned urbanisation leading to high population density; and expansion of the urban fabric in the form of informal constructions on slopes or landfills. Open public spaces can reduce the impact of a disaster during the disaster event phase and influence rehabilitation during the post-disaster phase (Choe et al, 2023). By considering the above, Omic´evic´and S ˇc´itaroci offer a comprehensive coverage that combines the domains of environment, natural resources, engineering, management and policy studies to address disaster risk and resilience in the green growth context in an integrated and holistic manner.…”

A Multi-Hazard Risk Assessment Model for a Road Network Based on Neural Networks and Fuzzy Comprehensive Evaluation

“…As people's living standards continue to improve, roads, an important characteristic of cities, play a key role in rescues and transportation [12,13]. On the one hand, road transportation is convenient, but also brings with it unavoidable risks [14].…”

Study on Dynamic Damage of Crash Barrier under Impact Load of High-Speed Train

“…In recent years, a large number of disasters have affected the safety of road engineering [1][2][3][4][5][6][7], among which railway engineering is one of the most seriously damaged objects. Train derailments not only cause a large number of casualties but also cause significant damage to railway infrastructure, especially when they occur in tunnels, where derailed trains run off the track into tunnel structures or even into other lines, causing secondary disasters, which pose a serious threat to the sustainable use of trains and tunnels.…”
