The first officially sanctioned taxi-hailing application in Beijing went online on Tuesday amid efforts to regulate the growing transportation service sector in the capital.

More than 15,000 Beijing taxis are cooperating with the new mobile-based app, called Feidi, Wang Runnan, technical director of Beijing Qihua Smart Transportation Co, the app's developer, said on Tuesday.

Wang said the company will work on expanding the coverage to include all 60,000 Beijing taxi drivers.
