Sustainable Transportation Performance Measures For Developing Communities

The concepts of sustainable transportation can be implemented if they are clearly defined, quantified, and applied in the decision-making process. This study addressed these aspects for two test beds. The first is the Mabopane Centurion Development Corridor (MCDC) located in a developing nation (South Africa), the other one is the Houston corridor located in a developed nation (United States of America). An index for sustainable transportation was developed that is based on the multi-attribute utility theory (MAUT) technique. Various models were used to quantify the selected performance measures at both the aggregate (groups of vehicles) and disaggregate (individual vehicle) levels. These measures were then used to determine the index values for the individual links and the corridors as a whole. It was illustrated that the methodology proposed in this study allows for comparisons between corridors, irrespective of functional classification, overall goals, mode, analysis year, or even nations.
