The Academic Theoretical Frameworks and through their rhetoric and implications of their intellectual base are considered an important foundation to build upon them in advancing the academic scientific research in certain jurisdiction, it has emerged the importance of studying these discourses ( frameworks) due to its knowledge connotations that appear directly or indirectly . In order to investigate the nature of their knowledge authorities which were founded by, and then may be adopted as a basis for future complement researches. As it is known that the properties of the scientific knowledge is being accumulated in their general form. This is what has pushed the research to review some models of discourses or frameworks in architectural researches. Due to the fact that the scientific aspects of architecture combines the fields of humanities with their normative discourses and the positive science with their natural theories – as building physics and structure and others.- the research interested in reviewing these discourses that belong to the field of humanities and specifically these research frameworks that studied the realm of Architecture and Religion. Since it is difficult of investigating their knowledge authorities that adopted in that realm compared to those that belong to the field of positivists science or of arguments governed purely mathematical laws. In order to investigate the nature of their knowledge authorities that adopted in these research frameworks or discourses, the research makes a matching between them and the Islamic intellectual knowledge structures, to measure the consistency between them.The research concluded that there are three powers of knowledge authorities in the jurisdiction (Architecture & Religion ) discourses or frameworks that posit the backs of post- graduate students - master's and doctoral degrees – researches, they were the Authority of Rhetoric , Authority of origin, and Authority of Permission, their impact rate varies between the samples that examined in the case study, in addition the research determine the nature of knowledge structures that adopted in these researches. The research has addressed a sample of researchers in the area referred above that accomplished in only one university in Iraq in the department of Architecture ,University of Baghdad due to the given size of the of the space allocated for research.

Read More ... When planning to do a port or a new road or when determine the turning traffic movements for any road, we must know the traffic movement on the road to determine the distribution and direction of the turning traffic, and we must know pedestrian traffic, parking and land uses adjacent because this will help to forecasting the magnitude of the changes in the movement of turning traffic in the future, which helps to determine the priorities of sustainable development required. The increasing population and the preparation of private vehicles of the most important factors that have helped to increase traffic congestion and transport problems and the growing proportion of traffic, causing accidents and pollution as well as large losses of the national economy. Pushing to put these problems to be addressed to search for the best possible means to be diagnosed and treated as soon as what can be achieved through the use of modern technology as a way analytical. It is no doubt that a GIS is one of the most important of these methods adopted in the world in support of the decision and personalized sites imbalance through adoption in identifying problems of traffic intersections and traffic streams through them and their sizes especially in the intersections of the main streets in large cities and neighboring land uses task scope regional service, such as universities and ministries. It also we can take advantage of modern technology through the use of Photographic technique and application of computer programs in the survey and analysis of turning traffic for these nodes to ease the pressure on those whom in charge of research to get the data for the streams of traffic and employ this technique along the style of GIS in the analysis and treatment, and this would save a lot of time, cost and effort with more accurate data. In addition, that is what this research will try to focus it through analytical situ study for the problem of the mother Baghdad university intersection in the city of Baghdad, with the two methods of modern technology.
