Abstract
One of the Challenging problems of Tehran metropolitan region is Air pollution. Suburban expansion in the form of sprawl patterns have created the travels and transportations, due to the dependence on personal vehicles contributes more than 85 percent of creators of air pollution. The article studied the role of transportation in emergence of urban air pollution in Tehran metropolitan region, have population more than 15.98 million. The method of this paper is of analytical and is based on the secondary data and traditions of the Quantitative research methodology. This article have been wrote in the context of Retroductive strategy and meta-analysis method and compositional research traditions. For analysis of suburban spatial transportation have used Raw Data Intra-Urban and suburban Data in 1395 Year And for spatial analysis of air pollution (PM2.5 and PM10), have been used The raw data from sensing stations and Landsat satellite images (OLI) for three selected days in 1392, 1393, and 1395 as survey samples in the ArcGIS software. The research findings indicate that due to the intensity of transportation flows in Tehran metropolitan, the suburb to the suburb, the suburb to the central city (Tehran) and vice versa, Air pollution center Rise cannot be attributed to Tehran alone, as the area of pollutant sources has been distributed within the "Tehran metropolitan region ".So, the amount of spatial correlation between air pollution maps and transportation flow maps in selected days (2 Bahman 1392, 5 Bahman 1393 and Dec. 7, 1395), in all cases indicated high spatial relations (more than 75%), Confirmation the idea of this paper. Analysis of this situation in triple loops also shows that the highest volume of transportation is in the city of Tehran (CBD), suburban and exurban areas, respectively and the distribution pattern and spatial accumulation of pollution are also subject to this situation.

Abstract
Assessment is one of the important methods in analyzing the accomplishment of Sustainable development and as one of the necessities of planning can identify potential and actual environmental effect that is emerged as a result of the construction and development and provides logical options to solve them. The purpose of the current research is to assess the environmental effects of multi-layer highways on the neighborhood. The research is applied In terms of purpose and descriptive in terms of nature. Moreover, this research is environment based and uses sustainable development in theory. In order to analyze the data, 8 neighborhood around the Sadr bridge (Tajrish, Gheytariyeh, Chizar, Zargandeh, Sadr, Rostam Abas, Ekhtiyarieh and Pasdaran neighborhoods) were chosen as the analyze unit. Assessment indexes were assed in term of social, skeleton, vision and health-hygiene, economic and ecologic and safety-security domains. statistical Qualitative and quantitative methods including one sample T test and Friedman test were used to rate the domains and spatial analysis methods (spatial statistics) were used to show the status of the neighborhood. We also used the TOPSIS technique and Iranian Leopold in order to rate the neighborhood in terms of environmental effects of multi-layer Sadr Bridge. Results of the assessment matrix showed that Sadr multi-layer project is confirmed by providing corrective options in activities with high and very high damage. Based on the research findings it was found that the neighborhoods around the Sadr multi-layer highway given the assed dimensions, each have a different susceptibility from the multi-layer Sadr Bridge. In this regard, the ecological and skeleton have the most susceptibility and the security each have the least susceptibility from the Sadr multi-layer Sadr bridge and in rating the neighborhood, Rostamabad had the most susceptibility and the Zarhandeh has the least susceptibility from the Multi-layer Sadr bridge.

Abstract
Urban highways, as one of the most important sectors of transportation, have always been one of the most challenging, both in terms of budget consumption and its spatial, social, economic and environmental impacts on the city. It has been urban elements. To this end, this study analyzes the impacts of inter-city highways, examines the theories of how to deal with this spatial element, as well as the factors involved. The type of research is applied-theoretical and the method is documentary-analytical. The sources of information used in this research are all documents, documents, books, articles, plans, and scientific research on urban highways. The results indicate that there are favorable and disagreeable views and views on the creation of inter-city highways. Modernist thinkers and urban engineers, advocates of urban highways, and later urban planners and geographers, are opposed to one-dimensional attention to these highways and inner-city development relying on highways. The results also showed that the inter-city highways had social, economic, physical and environmental impacts and, depending on the location conditions and the socio-economic characteristics of the location, these impacts were positive and negative in space. It looks around.

Abstract
Innopolis Daedeok is a beacon of scientific excellence and technological innovation, serving as the nerve center of South Korea's research endeavors. By leveraging the presence of esteemed research institutions and universities, this hub has created a fertile ground for commercializing cutting-edge technologies. The research methodology employed is descriptive-analytical and developmental in nature. The findings indicate that Innopolis Daedeok is strategically divided into five distinct regions, spanning 27.7 square kilometers, to achieve its operational objectives. Notably, 11% of South Korea's Ph.D.-level researchers are affiliated with Innopolis Daedeok. Currently, a workforce of 22,000 researchers and employees is engaged in advanced research, with 10% of the country's research workforce concentrated in this hub. The spatial expansion of Innopolis Daedeok has unfolded in four stages: the establishment of the Daedeok Science Town (1973-1993), the creation of innovation (1993-1997), the formation of an innovation cluster (1998-2003), and the growth stage of the innovation cluster (2004 to present). This evolution has enabled Innopolis Daedeok to become a global innovation hub, with a unique triple helix model of government, industry, and academia collaboration. The development and evolution model of Innopolis Daedeok is characterized by three distinct stages: the initial stage (science park model), the development stage (technopolis model), and the maturity stage (innovation cluster model). This model serves as a benchmark for other innovation hubs, highlighting the importance of strategic planning, collaboration, and investment in research and development.
