Analyzing the Role of Urban Engineering System in Controlling the Physical Development of Cities

Introduction and objects:The purpose of this study is to investigate the role of urban engineering system in controlling the physical development of Tehran. Physical development is controlled in a regular and organized manner when the criteria and framework for controlling urban development are specified and urbanism engineers are members of the Engineering System Organization as knowledgeable individuals, with the help of the power given to them by the Engineering System Organization, apply them in the city.

Research based on purpose, has an application and in terms of nature, has a survey method. In collecting data, the documentary and field methods were used. To compile and confirm the research indicators, the Delphi method was used in three stages of surveys of ten urbanism elders. One-sample t-test, Pearson correlation, multivariate recursion, heuristic factor analysis, Friedman ranking were used to analyze the data and Kolomogorov-Smirinov test was used to evaluate the normality of the data. The statistical population of the study includes 35 urban engineers with employment licenses, members of the Engineering System Organization of Tehran Province. The research indicators were measured by Likert spectrum with an average of 3 components and 26 components and 26 indicators. These components include comprehensive urban plan, passive defense considerations, justification plan to increase urban boundaries, justification plan outside urban boundaries, preparation of urban detail plan, urban adaptation of buildings, land separation plan and adaptation of urban land use.

According to views of experts, the average of all indicators is 4.01, which is higher than the assumed average (3). Using Pearson test, the highest Pearson link is between the control of physical development in Tehran and the criteria of land separation plan (r=0.787). The amount of variance explained by the control of urban physical development by the components of the forecast variable (0.43) is significant.

The results show that 43% of the control of urban physical development is affected by these variables (comprehensive urban plan, passive defense considerations, justification plan to increase urban boundaries, justification plan outside urban boundaries, preparation of urban detail plan, urban adaptation of buildings, land separation plan and adaptation of urban land use. ), which show a high degree of appropriateness and desirability and has the necessary explanatory and predictive power in the subject of research.
