Internal transportation system`s Strategic management resilience in Tehran region 1

Introduction
The resilient internal transportation system network is a system that is able to absorb the negative effects of turbulences, reorganize them and continue their function. Resilience is directly related to sustainability. The inaccurate usage of available capacities may reduce its` resilience and provide environment with irrecoverable harms. The main purpose of this research is to recognize the most effective managerial strategies in the resilience of internal transportation network with the emphasis on accessing environmental sustainable development in Tehran region one and provide a schema for it.
Currently, transportation used in urban communities is not stable due to the problems and challenges that occur in it. This instability has manifested itself in the first place in the excessive consumption of energy and fuels, then in the reduction of resources and finally in the increase of air pollution, even globally. Also, major problems and inadequacies in urban transportation affect the economy, society and urban environment as the main indicators of sustainability, which has made it more necessary to pay attention to the issue of sustainability and resilience of urban transportation. Given the existing problems with intercity transportation and low resilience at the city level; The present article seeks to achieve resilience methods of urban transportation by using management strategies to achieve sustainable environmental development in area one of Tehran in 1399.
Method
The method of present study is survey analytic and the sample group were 100 managers and experts of internal transportation network in Tehran region one during 2019 that were participated in purposive sampling method in the study. The data was gathered through researcher self-made questionnaire; through the factor analysis five factors of 1. Organizational capacity improvement (5 items) 2. Systematic management (9 items) 3. Risks` reduction (4 items) 4. Subtraction utilization (5 items) and 5. Information technology usage (3 items) were recognized and afterward, managerial strategies schema in internal transportation system network of Tehran region one was designed and based on that, it is possible to accurately and efficiently plan to improve managerial strategies and functions in internal transportation system network and environmental sustainable development.
Discussion and Results
 The current transportation system of region one of Tehran has major limitations such as low share of public transportation, high share of single-passenger cars, increasing distance between business and non-business trips, and inadequate structure and quality of the road network for pedestrian or use transportation. It suffers from cycling, which has led to complications such as traffic congestion, lack of stops, increased pollution, reduced mobility, increased fuel consumption and wasted energy. Policies and measures taken in response to the problems have had little success, mainly due to inconsistencies in planning and implementation on the one hand and a lack of comprehensiveness and foresight on the other. In addition, due to its high population density, the concentration of most administrative and economic centers in it and its special position in terms of geology, this region is one of the most sensitive areas in Tehran. Given the exposure to the threats posed by its location in the region, identifying the most effective strategic management indicators in transport network resilience necessitates research. Considering the current environmental situation of this region, such as the reduction of green space and open spaces, uncontrolled and non-standard construction, increasing the types of environmental pollution in this study has tried to examine and identify the most important and effective indicators. Strategic management strategies in the resilience of the intra-city transportation network In order to achieve sustainable environmental development, a model should be designed to measure and evaluate the resilience of intra-city transportation.
Conclusion
 This paper was presented with the title of strategic management model of resilience of urban transportation network with emphasis on achieving sustainable environmental development in area one of Tehran in 1399.  In this paper, preliminary indicators were extracted according to the studies, including research background, concepts and theoretical foundations related to the subject, criteria and components of resilience, sustainable environmental development, urban transportation network, and by interviewing elites and Specialists in transportation, traffic and urban management and the use of factor analysis techniques, five criteria: organizational capacity improvement, system management, risk reduction, use of alternative vehicle infrastructure, increasing the use of information technology were identified and prioritized. The results of this research are based on the theories of Cohen's development model with three economic dimensions with the aim of progress, social with the aim of equality and poverty reduction, ecological with the aim of natural resources and prismatic model of sustainability, sustainable development in four dimensions: environmental-economic-social and physical. Emphasizes on reducing ownership and use of personal vehicles, reducing fuel consumption, reducing traffic congestion and various pollutions.
