The City of Cape Town’s Transport Development Index (TDI) – the first to be developed in Africa – reveals that 95% of commuters making use of public transport in the city fall within the low and low to medium income groups. Furthermore, the low income group spends on average 45% of their monthly household income on transport. The article discusses the TDI, which was developed by Transport for Cape Town (TCT), the City’s transport authority, to evaluate the accessibility and related costs of transport to different income groups and users across the city. Following on from the TDI, Cape Town was evaluated in terms of the Arthur D. Little Mobility Index that is used to measure cities all over the world. The Mobility Index uses 19 different transport-related assessment criteria such as the financial attractiveness of public transport; the share of public transport in the modal split; roads density; cycle path density; smart card penetration; car sharing performance; public transport frequency; traffic-related fatalities; mean travel time to work; and density of vehicles registered, among others. With an overall score of 37 points, the City of Cape Town ranks 73rd out of 85 cities worldwide and 4th out of six in Africa.
