Abstract
One of the most important issues in the cities is the crisis management and resilience of the cities against the
Human-made crises such as war and terror. Transportation network as the vital artery of the city plays a vibrant
role in reducing vulnerability and facilitating crisis management in the city, such as proper access to residential tissues,
emergency evacuation of neighborhoods, access to vital emergency relief centers and military centers. Hence, It seems
necessary for cities to design a secure urban network includes a set of interconnected passages that have low vulnerability
to crisis, while also linking residential blocks, relief and rescue centers, military and Law Enforcement Centers
and the bases of the entrance and exit of urban areas uninterrupted. The above mentioned network will maintain its
accountability after the crisis, and relief and military efforts will not be disrupted by this, As a result, city preparedness
for attacks and riots will increase. This research was conducted with the aim of defining the Secure network of
urban roads and describing its features and methods of designing it in urban textures as well as operating it in the District
12 of Tehran. To design the safe network of the District 12, firstly, the existing status passages based on 9 indicators including
confinement, access to relief centers, access to green spaces and open spaces, access to military and law enforcement
center, passage widths, traffic conditions, Class height, building quality, and types of landuse by IHWP method and GIS
software techniques were analyzed from the perspective of crisis vulnerability. In the next step, passages with low vulnerability
and appropriate access to critical crisis management menus were selected as the main constituents of the secure
network and by doing some actions, the network structure and its interconnection were also provided. In the end, with the
aim of maintaining the safety and resilience of the network in the long run, some rules were developed that would only be
enforceable on safe network passages.
