Risks of transporting dangerous goods : South Durban case study.

Govan, Bhavesh Raman. January 2005 (has links)
Industry both consumes and creates an abundance of dangerous goods, which must be transported from producers to end-users. This creates opportunities for incidents, including traffic accidents, which could release poisonous, corrosive, flammable or carcinogenic substances into the environment. Releases of dangerous goods at a location may pose a significant threat to the health of the neighbouring population. The Durban South Basin, with its hazardous mix of heavy industrial, employment and residential areas, was chosen as the case study for research into the risks associated with the transportation of dangerous goods. High levels of traffic flow occur in this region and significant volumes of dangerous goods are transported on the roads within the basin. The objectives of this investigation were to: develop a methodology that may be applied to estimate the likelihood and consequences of releases of dangerous goods due to road accidents; and to evaluate the usefulness of this methodology by applying it to estimate the risks posed to the people residing in, working in and travelling through the Durban South Basin. The literature pertaining to risk assessment of dangerous goods transport was examined. A review was undertaken of the current state of the art and the theory and methodology used by previous researchers. As intersections provide greater opportunities for vehicles to be involved in accidents, traffic surveys were conducted at selected intersections within the Durban South Basin in order to obtain an indication of the flow of dangerous goods vehicles and the types of dangerous goods being transported through these locations. Two approaches were utilised to estimate the likelihood of dangerous goods accidents and releases at intersections: a deterministic model and an innovative method based on Monte Carlo simulation. Dispersion modelling and geographic information systems were integrated to estimate the impacts of accidental releases of dangerous goods at intersections. Queuing analysis was combined with dispersion modelling to estimate the risks posed to road users from dangerous goods releases. The investigation verified that dangerous goods transportation risk assessment could be performed even when there are substantial data uncertainties. Furthermore, in comparison to the deterministic approach typically used in transportation studies, Monte Carlo simulation facilitates a deeper understanding of the nature and distribution of dangerous goods accident risk. The results suggest that although dangerous goods accidents and releases are infrequent, the potential exists for very serious incidents involving large numbers of injuries. / Thesis (M.Sc.Eng.)-University of KwaZulu-Natal, 2005.

The identification of appropriate planning interventions to enable the minibus to make a more efficient contribution to public transport.

Kantilal, Neetha. January 1996 (has links)
The mini-bus industry has been hailed as a major breakthrough in public transport. It fills a much needed void in the hierachy of public transport. However, despite its success story the industry is facing problems. This study attempts to examine and understand the dynamics of the mini-bus industry in South Africa, with specific reference to mini-bus operations in the study area of Overport. The aim is to examine and highlight the problems in the industry and to formulate solutions and/or policy options for recommendations through the identification of appropriate planning interventions to enable the mini-bus to make a more efficient contribution to public transport. / Thesis (M.T.R.P.)-University of Natal, Durban, 1996.

The architecture of railway stations and transportation nodes, towards the design of a proposed new commuter railway station in Kingspark sports precinct.

Mtembu, Mxolisi Sikhumbuzo. January 2008 (has links)
In a world of increased daily travel, more efficient means of transporting people become all the more relevant as citizens constantly try to bridge time and distance in an effort to get to work and other meeting places. The ability to transport large numbers of people at the same time, establishes the rail transport as one such mode viable for this task. As a result, cities throughout the world constantly revive existing rail networks and introduce new ones to cater for this growing traveling demand of the 21 st century. The most popular forms of transportation in the city of Durban, namely the bus, taxi and private car are the main contributors to the traffic congestion and air pollution problems in the city, hence the need to reconsider the importance of the train. Following international precedent, South Africa is planning to revive its railway services by changing its image and ensuring passenger safety in order to establish it as a major public transport system (Ministry of transport, 2006). In creating the building form of railway station buildings, it is necessary to understand passenger movement and activity within the station as well as the spaces required for such activities. This is vital if the designer has to make a meaningful contribution to society though his building intervention. Railway stations do not function in isolation to other modes of transportation in the city, hence the need for this study to consider the station in a node or interchange context to enforce its role within the city's transportation system as a whole. / Thesis (M.T.R.P.)-University of KwaZulu-Natal, Durban, 2008.

Connection modelling as a mechanism for addressing social inequality in Durban's peri-urban built environment : a proposed public transport hub.

Cullen, Craig. 21 October 2014 (has links)
South Africa boasts such intrinsic beauty in its social and physical geography and at the heart of this beauty lie its people. For each culture that has fought for their beliefs and systems, wars have been fought and lives have been lost. One thing which remains constant however is the belief that we the people can work together to live in peace and harmony and leave a better place to those who come after. Apartheid South Africa was divisive in many ways and its results have left many wounds on the country’s architectural geography. Social inequality is manifest in the tapestry of everyday life and the Peri-Urban scars of our past have become vivid thresholds of crosscultural debate. The Apartheid planning model of disconnection through race and class has seen a massive effort to refocus on Durban’s urban core, whereas the rich tapestry of the Peri-Urban townships is often neglected. In order to reconnect the outer city geographies back into the urban whole an investigation into the theory of connection between people and their physical environment needs to be undertaken. This dissertation looks at how the theory of connection might enable a unified Durban and rehabilitate the tenderness of past planning processes. Public Transport is one such mechanism which can connect communities, no matter the distance nor socio-economic status and it is within this context that the dissertation offers new insight into the critical and exciting reconnection process. / M.

The hermeneutics of architecture as a means for transposing public perception : towards the design of a transport interchange in the Durban Central Business District.

Brett, David Tod. January 2011 (has links)
In South Africa today, railways, along with other forms of public transport have lost or in fact never had the same sense of sanguine appreciation that European stations embodied. Instead South African public transport systems, especially its railway networks, are perceived negatively by a large portion of the population and the vast majority of visitors to the country (Donaldson and Ferreira, 2008). The problem with the perceptions and judgments made by people with regards to architecture is that they often stand in contrast to each other. These disagreements are not only limited to laymen, as disagreements among critics often go beyond the mere subjectivity of taste or opinion, even extending to matters of fact (Bonta, 1979: 11). By extrapolating the process by which humans interpret the world around them, Hermeneutics attempts to define the determining factors behind subjective thought when making an accurate interpretation of text. In recent years these same techniques have been applied to the built environment in what can best be described as an investigation into the meaning of architecture, this investigation became known as ‘architectural hermeneutics’ (Bonta, 1979 and Snodgrass & Coyne, 2006). While hermeneutics does provide a method to deal with the problems associated with subjectivity, the tools needed to assess the validity of the resultant interpretations of architecture have not developed. In order to confirm the adequacy of any resultant interpretations the researcher must define and abstract the parts, which contribute to these interpretations, according to quantifiable guidelines that can then be measured and compared. The Guidelines utilised in this study are defined through the work of Norberg-Schultz, Thiis-Evensen, Alexander and Handa. Through the ensuing case studies this paper demonstrated that by designing architecture in accordance with its relationship to the surrounding environment and context, the designer becomes capable of generating a supportive architecture that can reaffirm its associated functions under a positive light. By creating a continuous structure between the new architecture and its context – that is in accordance with the ‘parts’ which make up the meaningful ‘whole’ – an architect of any background can create meaningful architecture in any context. / Thesis (M.Arch.)-University of KwaZulu-Natal, Durban, 2011.
