Urban and regional planning is done for development, and natural and man-made hazards are obstacles to development. War is one of those dangers which has always been with mankind and has become more widespread in recent decades by contributing to conflicts in the interests of countries. Therefore, the passive defense as a measure in the pre-crisis phase, with the goal of reducing the vulnerability of infrastructure, should be considered in planning. Due to its proximity to Tehran, Alborz road network, is the link between the capital and the northern and northwestern provinces as well as transit route to the neighboring countries of the Northwest. In addition, the high concentration of population and industry on the sides of the roads will create a threat to the province. Therefore, planning to reduce the vulnerability of this vital infrastructure in times of crisis and maintain its efficiency is of great importance. In the present study, in order to identify areas and roads vulnerable to the threat of war, the vulnerability indicators were first determined and ranked using IHWP method, and the vulnerability maps were prepared in the GIS environment. Then, using the SWOT tool, strategies to reduce the vulnerability of passages were defined and prioritized.
The results of the study indicated that the eastern and central parts of the main east-west axis of the province’s road network will have high vulnerability to war threats, while the most important capabilities and opportunities ahead, are the same axis. Therefore, by completing ongoing and planned projects to create parallel axes as well as bridge reinforcement and displacement of some land uses, it is possible to reduce the vulnerability of the Alborz province’s road network.
