An evaluation of Intelligent Transport System: A case study of the Bus Rapid Transit (BRT) Rea-Vaya in Johannesburg, South Africa

Khwathisi, Ntsieni Colin 18 September 2017 (has links)
MURP / Department of Urban and Regional Planning / This study focuses on the evaluation of intelligent transport systems making use of the BRT-Rea-vaya in Johannesburg as a case study. This study was motivated by the observation that few studies have been conducted in the study area that tackle explicitly intelligent transport systems evaluation. Intelligent transport systems can assist in improving private and public transportation systems and operations performance. In the public sector where various modes of transport such as the taxi, metro bus, metro rail, Gautrain and the BRT Rea-vaya operates, intelligent transport systems present opportunities for improving Level of Service (LOS) delivery. In Johannesburg, the BRT Rea vaya system was adopted by the Johannesburg metropolitan municipality to provide a safe, reliable, efficient and accessible public transport system. The BRT Rea vaya system is aimed at providing a better public transport, operating systems and service. For the BRT Rea vaya systems to achieve its primary goals and objectives, an intelligent transport system was incorporated to better manage the BRT Rea-vaya systems operations and activities. The study disclosed the status quo, opinions and attitudes of commuters regarding their experiences with the BRT Rea vaya public transport systems in Johannesburg. Furthermore, the study investigated whether the original objectives and aims of intelligent transport system in the BRT Rea-vaya have been meet. A central theme of the investigation is seeking to understand constraints and opportunities regarding BRT Rea-vaya intelligent transport systems‘ operations and activities in Johannesburg. The use of primary and secondary data such as questionnaires, key informant interviews, observation, journals and previous researches related to intelligent transport systems were used to acquire an in-depth understanding of the operational management of BRT Rea-vaya intelligent transport system. Collected data was analyzed using Statistical Package for Social Sciences (SPSS) with the aid of Microsoft Excel making use of descriptive statistics, regression analysis, cross tabulation and chi-square test. This was presented using tables, graphs, maps etc. Qualitative data was analyzed making use of a thematic approach. The study resonates in the need for rapid public transport systems to provide lessons for improving and adopting intelligent transport systems. As an end product, the research provided a framework of analysis on how to integrate intelligent transport systems in the context of Bus rapid transit systems.

Transport economic regulatory intervention in the transport infrastructure : a public-private partnership exploratory study

Maluleka, Khulumane John 31 January 2008 (has links)
The aim of this study is to determine whether the introduction of a transport economic regulatory authority would serve as a valid intervention mechanism in the Public-Private Partnership of the transport infrastructure in South Africa. In order to achieve this objective, the study focused on the analysis of the concept of Public-Private Partnership, and how it has unfolded in a number of industrialised countries. Much attention was devoted in examining how the Public-Private Partnership arrangements followed by the studied countries influenced the current transport infrastructure management process in South Africa. To deal with the above, a host of macro-environmental variables were analysed in respect of their potential impact on the South African Department of Transport. The establishment of various agencies by the Department of Transport was seen as a consequence of the influence of the prevailing environmental forces. The outcome of the analysis revealed that a sustainable transport infrastructural development is a product of genuine partnership between the public and private sectors. Competition for the market and the significance of such competition in the transport infrastructure were outlined. The main goal of competition within the context of this study is to diffuse the economic power of the toll road industry and the protection of the individual's fundamental rights. The study also unearthed a need to deepen the talent and skills of both public and private sector officials as this would enable them to protect the citizens' right to make well-considered choices in the toll road industry. The study identified a need to establish a transport economic regulatory authority that would control the market dynamics of power relationships in the transport industry. Such a body should be creative and need to have regulatory oversight over transport infrastructure. / Transport Logistics & Tourism / D. Comm.

A geographic perspective of labour-intensive methods in the development and maintenance of transport infrastructure

Musekene, Eric Nndavheleseni 04 1900 (has links)
The study investigates the extent of distributional impacts of labour-intensive road projects using a geographical approach. The aim is to evaluate infrastructural effectiveness. The central premise is that the interface between road investment and economic development has broad implications that are beyond transportation’s basic purpose of providing access and mobility. Communities are motivated by the outcomes and impacts of road infrastructure development in improving the productiveness of the economy, in line with socio-economic development and other multiplying effects. The objective was to describe the nature and delivery mechanisms of labourintensive road projects, evaluate the impact thereof on the project participants and their communities and explore the constraints and challenges experienced by these initiatives. The impact of the Gundo Lashu programme was measured, based on an assessment of programme outputs, outcomes and impacts, to determine whether the project had the desired effects on individual participants and their households. A matched control case study design, using a combination of qualitative and quantitative approaches was adopted. The study found that the Gundo Lashu programme had achieved the expected outputs in terms of the total number of jobs created, total road length constructed and maintained. However, the communities’ socioeconomic outcomes and the impacts of the programme on poverty and sustainable livelihoods were mixed. These conclusions re-affirm the notion that the development of rural road infrastructure alone by labour-intensive construction methods, is not sufficient in tackling poverty. While government is focusing on addressing unemployment and skills development through labourintensive road construction programmes, there is a need to ensure proper integration of government services to make a significant impact. Huge deficiencies exist in the inter-linkages between the programme planning process and the municipal planning system and that there are a number of management and planning, structural and functional, human resources and funding barriers to proper planning, implementation and monitoring of projects within the Gundo Lashu programme. Various challenges and barriers emanates from lack of coordination, political interferences and lack of strategic direction. Key recommendations include comprehensive road planning, better project targeting mechanisms, development of guidelines for future maintenance, skills training and capacity development, and resultsbased monitoring. / Geography / D.

The handling of fruit reefer containers in the Cape Town container terminal

Stander, Christo 12 1900 (has links)
Thesis (MCom)--Stellenbosch University, 2014. / ENGLISH ABSTRACT: The South African fresh fruit export industry is concerned about fruit and financial losses due to temperature breaks within the fresh fruit export cold chain. The Port of Cape Town plays a crucial role in the export process as the majority of fruit reefer containers that are exported through Cape Town are handled by the Cape Town Container Terminal. This study focuses on the container terminal leg of the fresh fruit export process. Observations made in the Cape Town Container Terminal, at shipping lines and exporting companies show that certain procedures are not always followed in the Cape Town Container Terminal and that congestion and ineffective working methods are causing breaks within the fresh fruit export cold chain. Temperature and time data received from Transnet Port Terminals, shipping lines and exporting companies were analysed for the container terminal segment of the export process. From the data analysis it is clear that there are a large number of breaks originating within the container terminal and that the port is not operating efficiently. The study identifies areas of improvement and makes recommendations on improving some of the issues discussed.

A descriptive study into the cold chain management of childhood vaccines by nurses in primary health care clinics in the uMgungundlovu District

Pillay, Shamla 03 March 2015 (has links)
Introduction This research was a descriptive study into the cold chain management of childhood vaccines by nurses in Primary Health Care Clinics in the uMgungundlovu District. It is imperative for health professionals to follow the procedures and policies set out by the immunisation and health manuals by of the World Health Organization. The success of any childhood vaccination programme depends on how well nurses and health professionals are able to adhere to the laws, regulations and procedures. There is also a need for clinics and health institutions to be flexible enough to deal with certain constraints so that the vaccination programmes are not interrupted for extended periods of time but rather run efficiently and benefit the intended population. As a result pandemics are easily avoided and a healthy generation of children will bring about a better society. Methodology The study was carried out in two phases i.e. an observational study and a self-administered questionnaire. In the first phase, the observational study was carried out at 14 different clinics in the uMgungundlovu District. In the second phase, the cold chain management of vaccines by nurses was explored by means of a self-administered questionnaire. Results The key findings of the observational study include that on most occasions policy was not being implemented. Furthermore there were no contingency plans to deal with equipment and electricity issues, no monitoring and evaluation systems, poor recording keeping, poor management of the cold box, access to stock and the actual management of the cold chain for vaccines. The self-administered questionnaire was completed by 276 nurses via a simple random sample from the different clinics. The most salient aspects of the research in this phase of the study revealed that education and experience of the nurses are crucial to the sustainability of the childhood immunisation programme. Not surprisingly, some of the findings were similar to that of the observational study. Issues surrounding equipment and electricity, monitoring and evaluation systems, poor recording keeping, poor access to stock and ordering of stock were prevalent in this phase of the research as well. Conclusion Recommendations have been made for ongoing communication between the Department of Health, the District Office of Health and clinics so that the short and long term problems identified are solved.

The development and application of a freight transport flow model for South Africa

Havenga, Jan H. 12 1900 (has links)
Thesis (DPhil (Logistics))--University of Stellenbosch, 2007. / South Africa currently experiences the double jeopardy problem of catching up to global economic competitiveness whilst at the same time feeling the pressures of sustainability management spearheaded by a global agenda. Global sustainability is defined as growth that is shared without depleting natural resources or damaging the environment. Academic disciplines are challenged to make a contribution and economics as such should contribute by providing the lead and lag indicators for the planning and measurement of scarce resources usuage. This integrative view includes economic sub-disciplines, such as logistics. This integrative view is an acknowledged part of the economics discipline, except that the macro-economic context of some sub-disciplines, such as logistics, often receives less attention during the course of academic activities. The distribution of resources and outputs in the economy is a logistics controlled cross-cutting factor, but suffers from a lack of macro-economic perspective, and lead and lag orientated measurement. This state of the affairs is a historic backlog of logistics and its specific position within economics. During the primary economic era the world began to configure networks and markets, which became more pronounced and settled with the dawn and settling of the industrial era. Logistics then was a “given” and did not receive much thought even as industrial, market economies developed. Transport was regarded as an administered cost, i.e. inefficiencies in logistics systems were evenly distributed between competitors, not giving any specific entity an advantage. With the advent of global competition and the diminishing returns on other cost saving measures, companies began to collaborate and integrate logistics functions within value chains, but the administered part of transport costs failed to receive the attention it required. In this way, global competitors did begin to experience disadvantages on a national level as whole economies suffered from inefficiencies in logistics and specifically transport systems.

Tshwane logistics hub : an integration of freight transport infrastructure

Botha, Maria 12 1900 (has links)
Thesis (MComm (Logistics))--Stellenbosch University, 2008. / One of the results of globalisation is that supply chains are getting longer, in both time and distance. For example, the local bookstore around the corner now competes with the bookstore in the USA. Logistics ties together geographically distant sources and markets. The implications of this are that there is a greater need for efficiency in specifically transportation and distribution networks. The integration of transport infrastructure into a logistics hub is seen as an enabler of distribution on a global basis. A solution to overcome the above complications is the development of logistics hubs as a means to simplify supply chain processes. Logistics hubs are generally defined as integrated centres for transhipment, storage, collection and distribution of goods (Jorgenson, 2007). Universally logistics hubs have intermodal or multi-modal solutions to abridge transportation difficulties and creating seamless movement of goods and in doing so optimising general operations. Freight shipments now have the ability to be consolidated at a central point and distributed from that point to its final destination. This creates added value for freight products. Customers now receive products at the right time, at the right place and in the right quantity, but with the benefit of paying less as a result of economies of scale created by the value added at the logistics hub. Logistics hubs are very well established internationally and many examples exist where these have been successfully built and implemented. This does not suggest that there is one specific recipe to success. Each region has its own demands which need to be satisfied. There are however numerous common characteristics which were identified during the course of the study. It is important for South Africa to integrate existing transport infrastructure to optimise logistics in the country and in doing so, ascertaining itself as a regional logistics hub.

Towards a more effective and efficient public transport system : a case study

Allopi, Dhiren January 1998 (has links)
Submitted in partial fulfillment of the requirements for the Degree of Doctor in Technology: Civil Engineering at Technikon Natal, 1998. / The Government of South Africa has recognised transport as one of its five main priority areas for socia-economic development. One of the Governments strategic objectives, as reflected in the white paper on National Transport Policy, is to promote the use of public transport with the goal of achieving a ratio of 80:20 between public transport and private car usage, as a long term vision. This is no easy task and in order to achieve this goal, an in depth analysis of the current transport situation is required. The structure and land-use patterns of most of the South African cities have forced the residents to be predominantly dependent on private transport, resulting in high car ownerships. Over the years, this has caused the traffic on the major links connecting the suburban areas leading to the city centres to be very high and some of them have already approached forced flow conditions during morning and evening peak periods / D
