The importance of road transport infrastructure development and maintenance in trade facilitation : a South African case
Road transportation is the most frequently used means of transporting goods and people in much of sub-Saharan Africa. Furthermore, because of the region's geographic nature, where many of the countries are landlocked, imports and exports of goods happen primarily by land and in this case by road …

The analysis and simulation of the spectral and statistical properties of road roughness for package performance testing
… but is ultimately caused by fluctuations in the road surface. This thesis introduces a universal analysis and classification methodology for discretely sampled road profile data. It originates from the premise that current laboratory simulation of the transport environment, which utilises vehicle …

Stress corrosion cracking and corrosion of carbon steel in simulated fuel-grade ethanol
… liquid fuel to replace conventional gasoline for road transportation. One of the key challenges for the future use of bioethanol is to increase its availability in the market via an efficient and economic way. However, one major concern in using the existing gas-pipelines to transport fuel-grade …

Retrospective analysis of blunt force trauma associated with fatal road traffic accidents in Cape Town (South Africa) over a two-year period
Road transportation systems are a global developmental achievement. However, with them comes increased morbidity and mortality rates in the form of road traffic accidents. In South Africa, there is a need to characterize road traffic accidents and the injuries associated with them, to determine the …

Quantifying the environmental impacts of selected sustainable transportation policies
On-road transportation policies could play a key role in reducing greenhouse gas (GHG) and air pollutant emissions via a wide range of strategies that can be classified into three groups: reduce, avoid, and replace. The objective of this dissertation is to prioritize on-road emission mitigation …
