An integrated alternative to road only or rail only transport does not exist in South Africa for domestic freight. This is in spite of the fact that national freight logistics costs are high, road infrastructure is challenged ...
This article presents the results of a comprehensive disaggregated commodity flow model
for South Africa. The wealth of data available enables a segmented analysis of future freight
transportation demand in order to ...

Due to the rapid deregulation of freight transport in South Africa two decades ago,
and low historical investment in rail (with resultant poor service delivery), an integrated
alternative to road and rail competition was ...
Despite two decades of visionary policies, problems within South Africa’s freight
logistics system remain. Logistics costs are high, the current road and rail solutions
will be unable to meet long-term demand for freight ...

The most common approach used internationally for forecasting international trade
containers is models based on the correlation between container trade and economic
growth. While the strong historical correlation is ...

The purpose of this study is to quantify the marginal external costs associated with
freight transport in South Africa. Six cost elements are included as externality cost items,
namely, costs related to accidents, ...

South Africa’s annual State of Logistics survey indicates that the
majority of dense, long-distance surface freight is transported by
road, placing severe constraints on the country’s freight logistics
infrastructure ...
This paper investigates the suitable location for an intermodal inland container
terminal (IICT) in the city of Cape Town. A container market segmentation approach is
used to project growth for container volumes over a ...
