Preliminary investigation of multi-hazard resilience analysis for urban transportation networks and data availability for hazard models and vulnerability of physical objects
HUB-Istanbul work package (WP) 2.6 aims to develop tools to analyse the multi-hazard resilience of urban transportation network in complex and evolving metropolitan environment, and propose a demonstrative application to a case study area: Fikirtepe in Istanbul, Turkey. Research outcomes will be conveyed by five deliverables. This document is the first deliverable, summarising the overall framework of analysis and required data for assessing physical vulnerability. Based on the framework, the second deliverable will deal specifically with another type of data required to evaluate traffic functionality of roadways and network performance. Based on the framework and datasets identified in the first two deliverables, the third deliverable will develop a probabilistic model to incorporate multi-layered analysis and data, which will be demonstrated by pilot examples. The fourth deliverable will present a thorough analysis of real-world transportation networks in the case study area, including mapping, network analysis and network performance evaluation. The evaluation results should be used to support decisions through mathematically formulated decision tasks, which will be illustrated in the fifth deliverable.
This first deliverable summarises and proposes the research objectives, the framework of multi-hazard disaster resilience analysis of urban transportation networks and data requirement for assessing physical vulnerability, which are accompanied with thorough literature review. Based on the development, major hazard threats and distributions of bridges are identified for the case study area, Fikirtepe in Istanbul, Turkey.
