    Funding for roads : understanding the South African road funding framework
    (2019-09-30) Van Rensburg, Johann A.; Krygsman, Stephan C.
    Background: A good quality road network holds numerous benefits to any country, but is dependent on sufficient and stable modes of funding and adequate financing. Funding for roads in South Africa is complex, controversial and faces different viewpoints. In this environment, it is difficult to implement any new form of road user charges, including the user-pay principle, or promote a sustainable road infrastructure policy framework. Objectives: This article examined the road funding framework in South Africa to fully understand its capability to fund the country’s road infrastructure network while quantifying and presenting the linkage between road-generated income, its distribution, allocation and the expenditure of these funds through a consolidated report and comparing the country’s income and expenditure on roads to international standards. Method: Numerous financial statements were assessed through a budget analysis to present the current road funding framework in South Africa in terms of the income generated from the road sector, its allocation, distribution and the expenditure of these funds. Local road funding trends were then compared with selected countries in terms of road-generated income, its allocation and expenditure. Results: South Africa’s current road funding framework collects a substantial amount from road users, but there is a mismatch between road-generated income collected and governmental road expenditure. Furthermore, South Africa’s road expenditure in not outside the norm compared to international countries. Conclusion: Investigation into the effectiveness of South Africa’s current road cost recovery methods is needed, and the impact of future technologies on its income-generating potential must be examined.

    The identification of possible future provincial boundaries for South Africa based on an intramax analysis of journey-to-work data
    (Operations Research Society of South Africa, 2008) Nel, J. H.; Krygsman, Stephan C.; De Jong, T.
    ENGLISH SUMMARY : National census data contain information on place of residence and place of work. It is possible to combine this information and create journey-to-work ows. The process of establishing these ows are presented in this paper. The intramax method is explained and used to identify functional regions based upon these ows. Interesting applications, such as the demarcation of regions in South Africa are considered and solutions to disputed areas are put forward. The process of the creation of the current provincial boundaries are discussed. New boundaries, based on the intramax analysis of the journey-to-work data are proposed for four or ve new provinces. Results compare favourably with those from a principal component and cluster analysis, which has previously been used to demarcate the South African space economy into a hierarchy of development regions.

    Toward spatial justice : the spatial equity effects of a toll road in Cape Town, South Africa
    (Center for Transportation Studies at the University of Minnesota, 2015) Van Dijk, Justin Tycho; Krygsman, Stephan C.; De Jong, Tom
    The present study sets out to provide an ex ante insight into the equity effects of a toll charge on the traffic diversions and geographical accessibility of work locations in the Cape Town metropolitan region, South Africa. Based on a static traffic assignment model and aggregate accessibility measures, computed in a GIS environment, the effects of a toll were estimated for different income categories for both a reference scenario and two toll scenarios. The findings indicate that particularly low-income commuters will divert to alternative routes. However, the results also indicate that the introduction of a toll will only have a limited impact on geographical accessibility. Nevertheless, because particularly low-income commuters are likely to divert to alternative routes, a toll should maybe not be levied on the road toward spatial justice without revenue redistribution or additional investment in the public transport system.
