Analysis of the Vulnerability of Urban Pathways and Networks of Tehran Municipality District 10 Based on the Passive Defense Principles

Communication paths are one of the most important elements in increasing or decreasing the vulnerability in a city. The abundance of access routes has significant impacts on the vulnerability mitigation and the number of casualties. This research is intended to find a relation between hierarchy of street network and earthquake، by using existing data about vulnerability of urban streets for district 10 of Tehran from passive defense viewpoint. This research is intended to find a relation between hierarchy of street network and earthquake، by using existing data about vulnerability of urban streets for district 10 of Tehran from passive defense viewpoint. In principle، passive defense in cities and centers of gravity or vulnerable centers of cities has close relations andis considered as one of the important steps in planning passive defense measures، prioritizing and classifying the significance of centers of gravity based on qualitative and quantitative criteria. Since the managerial approach and method of countering danger in cities should be preventive but not reactive type، therefore، this article is intended to use a passive defense approach. The present research is of applied type and the approach governing this research is analytical descriptive. The method of information collection is mainly documentary and interview and also according to research type، matrix method for local conformity district 10 of Tehran municipality is used from passive defense viewpoint. Human vulnerability against earthquakes، based on population density of the district، dense construction and results obtained from user matrix and its resultant chart are of high level. Having conducted analyses based on user matrix method and assessment of pathways inside district 10 and the results shown by charts 1 and 9، we can realize the significance of the existing pathways in this district and we will study the passive defense principles in these pathways، as well.
