To solve China’s endemic traffic problem, the ride-sharing company is working with local authorities on an initiative it calls Smart Transportation. Over 20 Chinese cities have adopted the program, which includes installing smart traffic lights and “reversible lanes” to improve flow during traffic peaks. In some locations, the system has reduced delays by up to 20%, an annual savings of 11.5 million commuter hours. This translates to increased turnover and revenue for Didi drivers, and a reduction in carbon emissions from idling cars.
