NuTonomy implements fleet management technology based on algorithms the US military uses for drone coordination, which the company said would help to reduce traffic and carbon emissions by making cars more efficient. Fazzoli and his colleagues published a study in Road Vehicle Automation in 2014 estimating 300,000 driverless taxis could replace the current number of taxis 780,000 while keeping wait time under 15 minutes. “That’s a 60 percent reduction in the number of vehicles operating in Singapore,”Frazzoli told MIT News’s Robohub. “This was a big sign of impact for [the Singaporean] government. At first we were asking them to let us test cars there—then they were asking us to come test.”
