Full textDuring the 1990s, governments, managements and unions have been focused upon improving the cost efficiency of firms. This focus has been strongest for firms in the public sector where improved outcomes can be expected to significantly improve the Gross Domestic Products of whole economies. This case study looks at the cost efficiency of NSW rail passenger services over a 41 year period to 1991/92, long suspected (but hitherto only tentatively demonstrated) as a paradigm of cost inefficiency. The case study focuses upon the use of the total factor productivity (TFP) index, as a datum point for measuring change in productivity in four markets: suburban, internrban, country and interstate passenger services since 1951/52. From this datum, changes over the years in management, technology and other external factors can be identified and assessed. The thesis identifies management quality (the organising element in the firm) as the preeminent factor in determining productivity change, and the role that new technology plays in its impact on failures in management. We establish the linkages between management and innovation, with TFP, pricing efficiency and economic resource use efficiency, to present a rich paradigm for assessing the economic performance of any business firm. Borrowing from systems theory and other management practices such as total quality management, we disaggregated the case firm into its component systems, sub-systems and processes, for separate study in relation to impact on TFP. The database for 41 years of rail behaviour is the richest ever compiled for any railway in Australia, and with enhanced modelling, enables a systematic treatment of the performance through time of State Rail's passenger services.

Full textENGLISH ABSTRACT: In April 2004, the then Transport MEC of the Western Cape, Tasneem Essop unveiled Government's grand vision of converting Klipfontein Road into a pioneering form of public transport called Bus Rapid Transit (BRT). BRT is the public transport system that the provincial government and City of Cape Town have selected to address South Africa's city transport problems, with a future looking perspective. BRT is characterised by dedicated bus lanes, which will be divided from the normal traffic lanes to ensure that 'express' buses can travel unhindered. Government envisages changing the 20 km Klipfontein Road Corridor stretching from the Inner City through Athlone/Gatesville to Nyanga and Khayelitsha into an activity axis of economic transformation, featuring bus stations, convenience stores, supermarkets, coffee shops and kerbside cafes. This vision of turning Klipfontein Corridor into a well of economic prosperity by using rapid bus transport is primarily what this study will focus on. We are asking whether this goal is attainable and what the positive and negative spin-offs are in respect of sustainable economic growth for the city and a reduction in racially rooted inequalities and inequities. Although a lot of the issues relevant for this study have been raised down the years of the MSDF (1993-1996), current literature on the Klipfontein Corridor is very limited as it is a first for the City of Cape Town and the government. In fact, the national and provincial governments in conjunction with the City of Cape Town have chosen the Klipfontein corridor as a pilot project, with a view to a national roll out in other provinces, if this venture proves successful.
AFRIKAANSE OPSOMMING: In April 2004 het die destydse Minister van Vervoer in die Wes-Kaap, Tasneem Essop onthul dat die regering die groot visie het om Klipfontein weg te transformeer deur gebruik te maak van publieke vervoer bekend as BRT. BRT is die publieke vervoersisteem wat die streeksregering en Kaapstad gekies het, om Suid Afrikaanse stede se vervoerprobleme, met 'n toekoms vooruitsig, op te los. BRT word gekenmerk deur spesiale busbane, apart van die normale verkeer, sodat busse ongehinderd kan voortbeweeg. Die regering beoog om die 20 km Klipfontein korridor te verander in 'n aktiewe node van ekonomiese transformasie met busstasies en winkelkomplekse. Die korridor strek vanaf die Binne Stad deur Athlone/Gatesville na Nyanga en Khayelitsha. Die visie van Me. Tasneem Essop om die Klipfonteinweg te ontwikkel in 'n vooruitstrewende ekonomiese gordel, is die fokus vir die studie. Ons vra of die visie haalbaar is, en wat die positiewe en negatiewe moontlikhede is met betrekking tot langtermyn ekonomiese groei en 'n vermindering in rasse-ongelykhede. Alhoewel baie van die relevante probleme reeds deur die Metropolitaanse Ruimtelike Ontwikkelingsraamwerk (MROR) behandel was, is huidige literatuur oor die Klipfontein projek baie beperk. Tans is dit 'n eerste vir Kaapstad en die regering, wat beoog om soortgelyke projekte uit te rol in ander stede reg oor die land, indien die projek suksesvol is.

Full textFor almost three decades practitioners, academics, consultants, and research organisations have identified 'attaining alignment between IT and business' (Luttman & Kempaiah, 2007), as a pervasive problem. Despite the wide acceptance of the term "strategic alignment", there was no consensus on how to achieve alignment. The research philosophy was of an interpretive study and an inductive research approach was used. The research strategy was by means of a case study, namely PRASA Western Cape, a business unit of Passenger Rail Agency of South Africa (PRASA). The time horizon for this research was cross sectional. For the data collection a semi-structured interview, supported by secondary data from the business plan and annual report, was used. The research problem was "PRASA has dysfunctional and fragmented institutional arrangements, resulting in misalignment between business and IT". The primary research question to address this problem was "How can PRASA manage strategic alignment between business and IT?" The aim of this research was to understand why the misalignment between business and IT strategies exists at PRASA. A further aim was to propose a guideline to manage alignment between business and IT strategies with the intention of overcoming the fragmented and dysfunctional institutional arrangements. To address resolving the research problem three theoretical models were used. The strategic alignment model was used to ascertain the strategic perspective of PRASA as well as to identify the external strategic fit and internal functional integration of an organisation. The second model used was the strategic alignment maturity model. This model was used to identify the alignment maturity of the business/IT strategies. The final model used was the balanced scorecard. Alignment is one of the best practices recommended by the balanced scorecard, and it recommends aligning all to the strategy of the company. The reason for using the balanced scorecard was that the company currently uses this tool to manage performance. The research finding concluded that PRASA had the strategic execution alignment perspective - business strategy dictates the IT strategy. The overall strategic alignment maturity of the organisation was found to be in initial process. The balanced scorecard methodology was known by all, yet few knew what the performance measures for the organisation was for the year. The triangulated conclusion was that strategic alignment between business and IT was a problem at PRASA. The recommendation was that the organisation conducts three surveys firstly to identify its strategic choice, secondly to identify the strategic alignment maturity and lastly to do a balanced scorecard best practice survey.

Full textInadequacies of the current public transport system cause an inconvenience for "normal able-bodied" passengers; however, it arguably isolates Special Needs Passengers (SNPs) from employment opportunities, recreational and educational opportunities. This research study focuses on what one might term mobility-handicapped persons who find it difficult to move around, or to hear and see. The term SNP or mobilityhandicapped persons encompasses more than just disabled persons. It includes customers laden with shopping bags, pregnant women, or someone with a broken leg, inter alia. The public transport system should enable persons with disabilities to experience the most optimal level of independence. It is crucial to have an accessible public transport system, because this is the first step in achieving independence for many SNP's. At present the system does not even satisfy the needs of able-bodied persons. How then is it supposed to respond to Special Needs Passengers? The public transport system can be divided into 4 categories namely, Infrastructure, Shared Road and Pedestrian Environment, Information and Vehicles. At present, these components of the system do not function efficiently. This research study was undertaken from three main perspectives in regard to the City of Cape Town: • The performance of the public transport system with reference to SNPs, • The performance of the city in terms of it's urban qualities and SNPs, and • The adequacy of the existing legal provisions and policy frameworks with reference to SNPs.

Full textThis research investigates and presents selected issues and aspects related to the railway mobile network (GSM-R) analysis and its shortcomings. Research studies show that millions of South Africans commuters are dependent on trains for daily movement activities, which significate contribute towards economic growth. Over the two decades, the exponential growth in wireless broadband service indicates the need for GSM-R improvement so that it can support the modern IP based protocol. The principle of implementing the digital network in railway already demonstrated significate improvement in the railway environment, especially in communication and signalling. Train traffic and train communications are the most critical aspects of railway scenarios due to safety and reliability. Both features form fundamental content to this research thesis. The exponential increase in Internet protocol (IP) based services and higher bandwidth requirements in modern technology applications have pushed the current Global system mobile for railway (GSM-R) technology to its maximum capacity as such the (GSM-R) platform is going to obsolete soon. There is a great need for the development of improved IP based networks for the future of the next generation network for fast smart trains to meet desired higher data low latency while improving quality of service (QoS). The focus of the research study is on modelling of an effective sharing method between public LTE and LTE-R without addition mobile infrastructure by utilizing train access unit (TAU), the main purpose is for public network (LTE) to handle railway emergency service including drop calls to improve quality of service (QoS). The second focus is an improvement of signal reception by spreading signals over wide spectrum range by utilizing Orthogonal variable spreading factor (OVSF) technique where LTE-R is not deployed as noted that this technique is deployed in the 3G network. The proposed scheme has adopted features in modern evolution communication and both scenarios were investigated modelled and simulated with comparison results showing better improvement in proposed conditions, there are many challenges in high-speed railway such as handover procedure and Doppler shift due to the velocity of the moving train.LTE-R has provided many solutions such as seamless handover, capacity availability as well as enhanced performance in both uplink and downlink. Digital evolution for railway GSM-R has been deployed in most developed countries in Europe and also expanded into Africa, there is a greater need for the seamless network to be developed due to an increased number of packet based services. Urban rail is the backbone of public transport in South Africa which is the Passenger Rail Agency of South Africa (PRASA). PRASA, and is the parent operator. Currently, PRASA has implemented digital railway network (GSM-R) to meet a high standard in railway. Modem demand and challenges require a cost-effective system to support IP orientated systems due to an increased number of packet-based services in the railway sectors.

Full textENGLISH ABSTRACT: This assignment explains the search for a mechanism that can increase tourism flow by improved utilisation of airline capacity. The inherent characteristics of air transport indicate that the industry is subject to low short term marginal costs and that it is very tempting to award discount tariffs for last minute bookings. The challenge to management is to attract new passengers with discount tariffs without loosing full tariff passengers. Travel clubs are one of the mechanisms that are utilised to achieve aforementioned objective. These clubs offer mainly discount tariffs on hotel accommodation, car hire and airline tickets to their members. The acceptability of a travel club that applies restricting measures such as for example short notice periods, adaptable depart and return dates and shortened lead times have been tested in the South African market. The majority of respondents surveyed were in favour of such a travel club. An important finding is that South Africans are prepared to travel in a chosen month but that the travel dates within that month are adaptable in exchange for discount tariffs. The research also indicate that the availability of funds was decisive in the decision to travel or not to travel over seas. In order to overcome this problem the introduction of a providence account is recommended as part of the travel club's products. The challenge for the travel club is thus to consolidate the demand and to match it with the excess airline capacity.
AFRIKAANSE OPSOMMING: Hierdie werkstuk beskryf die soeke na 'n meganisme wat toerismevloei kan verhoog deur die verbeterde kapasiteitsbenutting van lugvervoer. Die inherente kenmerke van lugvervoer toon dat die bedryf onderhewig is aan lae korttermyn marginale koste en dat die versoeking groot is om afslagtariewe vir op die nippertjie besprekings toe te staan. Die uitdaging vir die bestuur is om nuwe passasiers met afslagtariewe te lok sonder om voltariefpassasiers prys te gee. Reisklubs is een van die meganismes wat gebruik word om die voorgenoemde doelwit te bereik. Hierdie klubs bied hoofsaaklik afslagtariewe op hotelverblyf, motorhuur en vliegtuigkaartjies aan hul lede. Die aanvaarbaarheid van 'n reisklub wat beperkende rnaatreels soos, byvoorbeeld, kort kennisgewingstydperke, aanpasbare vertrek en terugkeer datums en verkorte leityd toepas, is in die Suid-Afrikaanse mark getoets. Die meerderheid van respondente in die ondersoek was ten gunste van so 'n reisklub. 'n 8elangrike bevinding is dat Suid-Afrikaners bereid is om in 'n gekose maand te reis, maar dat die spesifieke reisdatums in daardie maand aanpasbaar is in ruil vir afslagtariewe. Die navorsing toon ook dat die beskikbaarheid van fondse deurslaggewend is in die besluit om oorsee te reis of nie. Om hierdie probleem te oorkom word die instelling van 'n voorsieningsrekening aanbeveel as dee I van die reisklub se produkte. Die uitdaging aan die reisklub is dus om die vraag te konsolideer en dan af te stem op die oormaatkapasiteit van die lugrederye.

Full textThe South African economy requires effective low cost passenger transport in order to provide sufficient time and place utility for its population. The role that long distance passenger transport plays within this economic framework is important and ranges from inter city transport of passengers traveling for work and private purposes to that of metro transport. It is also important to note that long distance passenger transport plays an important role in the development of rural areas. Huge potential also exists for long distance passenger transport to assist in the development of the tourism industry. Long distance rail passenger transport forms an integrated part of the long distance passenger market. Due to the characteristics of long distance rail passenger transport this form of transport is specially conducive to providing low cost transport to low income groups. This situation enhances development and social interaction of the community in different geographical areas. Although long distance rail passenger transport plays an important role in the national economy the service has traditionally not generated a profit. The reasons for this situation are diverse and complex. This study addresses some of the traditional managerial approaches towards the business. A model is developed to enable management to focus on detailed service-level management that will enhance a higher service level with lower associated costs. This study focuses on service profitability management with the associated costing and pricing methods, and concomitant management information systems. During the discussion of these specific issues some of the cost and revenue deficiencies are identified, and possible solutions are proposed for these problems. Concerns with the traditional costing method are discussed in this study, where after a new model is developed to incorporate all costs that are necessary for product costing. The main reasons for adapting a different approach to costing of services are as follows'. Accurate costing of services enables management to decide on the improvement, continuation or discontinuation of a certain service. Service costing is used as a decision tool for the determination of fares for each service that is provided. The costing model incorporates the reclassification of expenses and costing of services according to their life cycle. For the purpose of arriving at a revenue level that should satisfy sustainable economical development and specific company requirements namely profitability, this study develops a method for calculating fares for long distance passenger rail transport. This method includes internal as well as external environmental issues. The primary requirement for a service profitability model is for management to obtain the relevant information that would enable such a model to function effectively. Due to the purpose of the study, namely to develop a decision model for management a project management approach for the development of a management information system is discussed. This model is related to a long distance rail passenger organization and highlights specific management information that is required for product profitability modeling. Finally this study recognizes that further research needs to be conducted to develop new strategies to decrease cost and increase revenue, with a satisfactory level of service.

Full textCommuter rail in South Africa faces many challenges as a result of a long history of inadequate investment in rail rolling stock, infrastructure, operations as well as the loss of appropriate managerial and technical (engineering) skills within the industry. Over time, commuter rail services have continued to fail to respond adequately to the changing passenger demands. On the other hand mobility has undergone constant change in terms of both population growth and spatial patterns. For an effective and viable country, the transport infrastructure and operations have to respond to this continual process of change. From the transport context, South Africa is still haunted by its poor transport legacies of the past, which emerged mainly as a result of dysfunctional institutions. The dysfunctional institutional arrangements have resulted in poor accountability in the provision of public transport services, which were found to be largely disempowering. Government‘s socio-economic and transport policies could not be supported adequately by such institutional arrangements. As South Africa embarks on a journey of turning its public transport system around, the challenges for public transport are to simultaneously transform through meaningful integration, whilst at the same time enhancing capacity through upgrading and modernization in order to meet long-term needs of the economy. This research focuses on the impacts of urbanization, commuter rail network and planning interventions aimed at an integrated public transport solution. Firstly, the research investigates the impact of urbanization in relation to public transport and in addressing the ongoing challenge of rapid growth and thereby perpetuating social, economic and spatial inequalities. Secondly, there is a disjuncture between legislation and implementation that the research investigates. Thirdly, the study investigates the connectedness of Gauteng in relation to economic opportunities, social facilities and amenities. It aims to explore the extent of integration of Gauteng institutionally, spatially and socio-economically. The study concludes that transportation is the single most important factor in shaping the economy. Transportation should therefore be highlighted in the spatial development planning framework and processes in Gauteng. The key in addressing the impact of urban rapid growth on commuter rail is managing land use and transport networks in such a way that the highest level of access to services and employment opportunities are maintained.

Full textConsiderable research on public policymaking has been carried out over the years. A number of theoretical frameworks have been developed to try to understand the complexities of the policy process. Nevertheless, the implementation of policy remains, as deLeon and deLeon (2001) state “the most devilish of wicked problems”. It is this wicked problem that this thesis attempts to comprehend a little better in the context of public transport. There is a broadly expressed belief in South Africa that while we have developed some fairly robust public transport policies, we fall down when it comes to the implementation of these policies. However, policies are not equally complex in nature and surely therefore not equally demanding in implementation. While it is accepted that a number of political, economic and social factors are necessary for policy implementation, it is nevertheless hypothesised that the nature and complexity of a policy will influence the paradigm within which implementation will take place. Furthermore, the ‘success’ of the implementation process needs to be located within the context of the specific implementation paradigm. The objective of this thesis has been to (i) identify and (ii) apply an appropriate policy implementation framework or model to the implementation of the Bus Rapid Transit (BRT) programme in South Africa to understand the BRT policy implementation process that has emerged thus far and whether its very nature and characteristics place it within a certain policy implementation paradigm.

Full textMore time series forecasting methods were researched and made available in recent years. This is mainly due to the emergence of machine learning methods which also found applicability in time series forecasting. The emergence of a variety of methods and their variants presents a challenge when choosing appropriate forecasting methods. This study explored the performance of four advanced forecasting methods: autoregressive integrated moving averages (ARIMA); artificial neural networks (ANN); support vector machines (SVM) and regression models with ARIMA errors. To improve their performance, bagging was also applied. The performance of the different methods was illustrated using South African air passenger data collected for planning purposes by the Airports Company South Africa (ACSA). The dissertation discussed the different forecasting methods at length. Characteristics such as strengths and weaknesses and the applicability of the methods were explored. Some of the most popular forecast accuracy measures were discussed in order to understand how they could be used in the performance evaluation of the methods. It was found that the regression model with ARIMA errors outperformed all the other methods, followed by the ARIMA model. These findings are in line with the general findings in the literature. The ANN method is prone to overfitting and this was evident from the results of the training and the test data sets. The bagged models showed mixed results with marginal improvement on some of the methods for some performance measures. It could be concluded that the traditional statistical forecasting methods (ARIMA and the regression model with ARIMA errors) performed better than the machine learning methods (ANN and SVM) on this data set, based on the measures of accuracy used. This calls for more research regarding the applicability of the machine learning methods to time series forecasting which will assist in understanding and improving their performance against the traditional statistical methods
Die afgelope tyd is verskeie tydreeksvooruitskattingsmetodes ondersoek as gevolg van die ontwikkeling van masjienleermetodes met toepassings in die vooruitskatting van tydreekse. Die nuwe metodes en hulle variante laat ʼn groot keuse tussen vooruitskattingsmetodes. Hierdie studie ondersoek die werkverrigting van vier gevorderde vooruitskattingsmetodes: outoregressiewe, geïntegreerde bewegende gemiddeldes (ARIMA), kunsmatige neurale netwerke (ANN), steunvektormasjiene (SVM) en regressiemodelle met ARIMA-foute. Skoenlussaamvoeging is gebruik om die prestasie van die metodes te verbeter. Die prestasie van die vier metodes is vergelyk deur hulle toe te pas op Suid-Afrikaanse lugpassasiersdata wat deur die Suid-Afrikaanse Lughawensmaatskappy (ACSA) vir beplanning ingesamel is. Hierdie verhandeling beskryf die verskillende vooruitskattingsmetodes omvattend. Sowel die positiewe as die negatiewe eienskappe en die toepasbaarheid van die metodes is uitgelig. Bekende prestasiemaatstawwe is ondersoek om die prestasie van die metodes te evalueer. Die regressiemodel met ARIMA-foute en die ARIMA-model het die beste van die vier metodes gevaar. Hierdie bevinding strook met dié in die literatuur. Dat die ANN-metode na oormatige passing neig, is deur die resultate van die opleidings- en toetsdatastelle bevestig. Die skoenlussamevoegingsmodelle het gemengde resultate opgelewer en in sommige prestasiemaatstawwe vir party metodes marginaal verbeter. Op grond van die waardes van die prestasiemaatstawwe wat in hierdie studie gebruik is, kan die gevolgtrekking gemaak word dat die tradisionele statistiese vooruitskattingsmetodes (ARIMA en regressie met ARIMA-foute) op die gekose datastel beter as die masjienleermetodes (ANN en SVM) presteer het. Dit dui op die behoefte aan verdere navorsing oor die toepaslikheid van tydreeksvooruitskatting met masjienleermetodes om hul prestasie vergeleke met dié van die tradisionele metodes te verbeter.

Sengwalwanyaki šišo se ahlaahlile mekgwa ya kakanyo ye e fapafapanego ka bophara. Dipharologanyi tša go swana le maatla le bofokodi le go dirišega ga mekgwa di ile tša šomišwa. Magato a mangwe ao a tumilego kudu a kakanyo ye e nepagetšego a ile a ahlaahlwa ka nepo ya go kwešiša ka fao a ka šomišwago ka gona ka tshekatshekong ya go šoma ga mekgwa ye. Go hweditšwe gore mokgwa wa poelomorago wa go ba le diphošo tša ARIMA o phadile mekgwa ye mengwe ka moka, gwa latela mokgwa wa ARIMA. Dikutollo tše di sepelelana le dikutollo ka kakaretšo ka dingwaleng. Mo k gwa wa ANN o ka fela o fetišiša gomme se se bonagetše go dipoelo tša tlhahlo le dihlo pha t ša teko ya tshedimošo. Mekgwa ya nepagalo ya go ithuta ka metšhene e bontšhitše dipoelo tšeo di hlakantšwego tšeo di nago le kaonafalo ye kgolo go ye mengwe mekgwa ya go ela go phethagatšwa ga mešomo. Go ka phethwa ka gore mekgwa ya setlwaedi ya go akanya dipalopalo (ARIMA le mokgwa wa poelomorago wa go ba le diphošo tša ARIMA) e šomile bokaone go phala mekgwa ya go ithuta ka metšhene (ANN le SVM) ka mo go sehlopha se sa tshedimošo, go eya ka magato a nepagalo ya magato ao a šomišitšwego. Se se nyaka gore go dirwe dinyakišišo tše dingwe mabapi le go dirišega ga mekgwa ya go ithuta ka metšhene mabapi le go akanya molokoloko wa dinako, e lego seo se tlago thuša go kwešiša le go kaonafatša go šoma ga yona kgahlanong le mekgwa ya setlwaedi ya dipalopalo.
