The study responds to the increasing effect that climate change has on earth and society. In a global context of rapid urbanization and population growth the project aims to establish the role that architecture can play in the mitigation of climate change. It addresses the embodied energy and carbon footprint of architecture in an urban context. The architectural building type that will be investigated is a transport interchange, specifically the BRT terminal at Pretoria Main Station and associated prototypical BRT stations. An architectural response that promotes public transport use will be investigated. The proposed transport interchange will act as a seam to linking Salvokop with the city, while linking the whole of Tshwane. The architectural intervention will use strategies to respond to predicted climate changes for Tshwane, and adopt strategies to mitigate it. Architectural technologies will be investigated to ensure that the structure has a low carbon footprint and low embodied energy. Through energy conscious design strategies the energy use of the structure will be kept to a minimum. The design will also address the social and historical context of the Pretoria Main Station, to ensure a coherent transport interchange that integrates all modes of transport. The design will contribute to the historical character of the site with an ecosystemic layered approach, adding new functions and layers to the existing, to ensure its adaptability and sustainability. This study forms the part of a departmental research study through the department of Architecture at Pretoria University - “Environmental potential” and the United Nations Development Programme [UNDP] and Global Environment Facility [GEF]. It aims to comply with the prerequisites for an M[Prof]Arch degree while achieving the goals and objectives set by the research study. / Dissertation (MArch(Prof))--University of Pretoria, 2010. / Architecture / unrestricted

Text in English / An improved roads and public transport system also referred to in this research as road-transport, is strategic to economic growth in countries worldwide. This is why the improvements relating thereto have been prioritised by governments in developing economies such as South Africa. The problem that therefore informed the research in this study is that ever since the improvements on road-transport in South Africa, the implications thereof on the role of the Tshwane Metropolitan Police Department (TMPD) have not been studied, to understand the associated dynamics. The dynamics relate to how the road-transport improvements have swayed the role of law enforcement in the City of Tshwane. To unpack the dynamics, the study posed the question: What are the implications of the road-transport improvements on the role of the TMPD? In an attempt to answer this question, the study premised itself on exploring one primary aim, which is: to explore the implications of the road-transport improvements, on the role of the TMPD. To operationalise this aim, the study used three research objectives, which are: to describe the road-transport improvements In South Africa; to explain the role of the Tshwane Metropolitan Police Department; as well as to identify factors that hinders the effectiveness of the TMPD. The research used a qualitative approach wherein primary data was collected using interviews. The research showed that road-transport improvements in South Africa can be summarised into two categories. These are traffic improvements and improvements in public transport. The research also found that the role of the TMPD include traffic policing, by-law enforcement, crime prevention, crime Investigation and crowd management. Although the role of the TMPD is regulated properly, the study shows that this law enforcement agency was constrained by a number of challenges. The challenges include: lack of clarity in their crime prevention mandate; limited investigative powers; balancing their enforcement and crime prevention mandates; poor training in crowd management; staff shortages; resource problems; and administrative challenges. To deal with the problems thus requires strong management and leadership within the institution. / Police Practice / M. Tech. (Policing)
