    The impact of gated communities on spatial transformation in the Greater Johannesburg area
    (Report Series produced by the South African Research Chair in Development Planning and Modelling, School of Architecture and Planning, University of the Witwatersrand., 2012-08) Landman, Karina; Badenhorst, Willem
    Gated communities in south Africa have increased tremendously since the late 1990’s, with various types spreading across the urban landscape. they can broadly be divided into two groups, namely enclosed neighbourhood s and new security developments. Enclosed neighbourhoods refer to existing neighbourhoods that have been fenced or walled in and where access is controlled or prohibited by means of gates or booms erected across existing roads. New security developments are private developments in which the entire area is developed by a private developer. these areas/buildings are physically walled or fenced off and usually have a security gate or controlled access point, with or without a security guard. this type can include large security estates, gated townhouse clusters/complexes and gated apartment complexes. these three sub-types are predominantly residential. new security developments can, however, also include gated offi ce parks and gated mixed-use developments (Landman 2012). As a signifi cant contributor to urban spatia l transformation, there is a need to understand the current extent and impact of different types of gated communities in the greater johannesburg area and implications for urban restructuring and sustainable development.

    The impact of gated communities on spatial transformation in the Greater Johannesburg area
    (South African Research Chair in Development Planning and Modelling, School of Architecture and Planning,University of the Witwatersrand., 2012-08) Landman, Karina; Badenhorst, Willem
    The main research question relates to the impact of gated communities on urban spatial transformation in the greater Johannesburg area. This translated into three objectives, namely: 1. To determine the extent of different types of gated communities in the City of Johannesburg. 2. To determine the impact of gated communities on spatial transformation in relation to processes of social, economic, environmental, institutional and political change. 3. To identify the implications for spatial restructuring and sustainable urban development in the City of Joburg.

    Mobility in the Gauteng City-Region
    (2014-08) Gotz, Graeme; Wray, Chris; Venter, Christo; Badenhorst, Willem; Trangoš, Guy; Culwick, Christina
    Mobility in the Gauteng City-Region has been written in a remarkable moment in the history of transport development in Gauteng. On the one hand the region appears to be in a new ‘golden era’ of transit infrastructure design and investment, as well as long-term planning for ever-growing commuter transport needs. On the other hand, the transport difficulties faced by the Gauteng City-Region’s (GCR) fast-growing population, as well as the many financial, spatial, social, economic and environmental challenges that flow from the region-wide architecture of this population’s daily commuting, appear to be growing ever more acute. It is, therefore, important to delineate the existing flows of traffic across the GCR; to understand the challenges of transport efficiency, access and affordability; and to gauge the impact of key transport interventions like the Gautrain Rapid Rail Link, the Gauteng Freeway Improvement Programme and associated e-tolling, and municipal Bus Rapid Transit (BRT) infrastructure. The report is structured as follows: a summary of recent transport infrastructure projects and key transport challenges are described in Chapter 1 written by Graeme Gotz and Chris Wray. The second and third chapters, by Prof Christo Venter and Willem Badenhorst, provide an in depth analysis of the 2011 Quality of Life survey transport questions, including the generation of a Quality of Transport Index. In Chapter 4, GCRO researcher Guy Trangoš provides a multi-scalar analysis of the public space design around four existing Gautrain stations – valuable research to be considered by authorities should the proposed extensions to the Gautrain go ahead. An often ignored but, from a sustainability perspective, an increasingly important aspect of transport is non-motorised transport (NMT). The report concludes with two NMT chapters by GCRO researcher Christina Culwick, exploring the state of NMT in the GCR and portraying the challenges and potential opportunities for the future of NMT in the city-region. It is not within the scope of a report such as this to review every strategic intervention, nor critically assess every challenge. However, a wide-ranging analysis of the current ‘state of mobility’ in the GCR, and the impact of key infrastructures – or the consequences of their absence – is warranted. Within the frame of the enormous scale of transport planning and infrastructure development underway, as well as the GCR’s many deep and enduring transport challenges, it is hoped that this report will make a contribution to understanding past and current trends, the impact of and (missed) opportunities in key infrastructure investments, and some of the key current priorities that need more attention in this new ‘golden age’ of transport planning.
