CHANGSHA -- China's first route for intelligent driving buses on open roads was put into trial operation in Changsha, capital of Central China's Hunan province on Friday.

The demonstration bus line measures 7.8 km with a total of 22 stations on the two-way journey in the city's Xiangjiang New Area. During the trial operation, four electric intelligent driving buses will be put into use, according to sources with the management committee of the area.

Passing through traffic lights, making turns and stopping at the stations, one of the intelligent driving buses successfully finished the whole journey along the scheduled route on Friday morning without a driver.

The Xiangjiang New Area aims to build national smart bus demonstration lines to promote the establishment of professional standards for intelligent driving buses, which can be promoted in the domestic market.
