Use All Generation of Crime Prevention through Environmental Design (CPTED) for Design urban Historical Fabric (Case Study: The central area of Tehran Metropolis, Eastern Oudlajan)
Abstract In recent years a new approach has been developed to control and evaluate urban construction. Investigation of spatial engineering factors and their effects on decreasing urbanization values, effects of spaces on the crime rate increase is a new approach to urban construction, management, and planning. Therefore, using of Crime Prevention "Through Environmental Design" (CPTED) focuses on urban design. And it always follows the principles of anti crime in places. This article examined the first and second generation of CPTED, and developed a third generation one. Then, tried to look at spatial aspects and factors, show the effects of urban space on the severity of the occurrence and then hide the crime. The results show that, within the historical range of Oudlajan, the high volume of textile problems, and large numbers of crime, are hidden in the backdrop of many historic buildings. This paper has been compiled by descriptive analytic method and gathered data and questionnaires. Simultaneous study of the first and second generation of CPTED and comparing them with the status of the metropolitan tissue of Tehran (central core) led us to describe the production of the third type. Finally, the recognition and information were obtained from this historical context and historical context approach, we arrived at a graph and strategic map for this region. Based on the localized CPTED (type 3) the general view is that the process should move towards modifying the whole tissue structure. Because this range acts as the central core and the pole. The results show that buildings with religious activity and similar themes have not moved along with rebuilding or retrofitting processes. And the weakness of location based factors has heightened crime rates and increased resident dissatisfaction.
