Johannesburg’s Bus Rapid Transit (BRT) system Rea Vaya—one of the continent’s first public bus systems and first African BRT— has saved South Africa as much as $890 million so far (2009-2014), by reducing travel time, improving road safety, and cutting down on carbon emissions, according to a recent report by the New Climate Economy, a project affiliated with the World Resources Institute (WRI).
The Rea Vaya bus system, built in 2009, runs on low sulphur diesel and follows predetermined routes in their own lanes, cutting down on the time spent cruising along the congested streets of Johannesburg. Here are those savings, as calculated by the WRI:
| Benefit | Savings (USD million) |
|---|---|
| Travel time savings | 331 |
| Improved road safety | 268 |
| Increased physical safety | 141 |
| Operating cost reduction | 170 |
| Travel time lost during construction | -38 |
| CO2 emissions reduction | 18 |
