Road intersection travel efficiency increases in GDD

The travel efficiency at the road intersections in Guangzhou Development District has been greatly increased since it reached a 460-million-yuan ($71 million) smart transport cooperation with Baidu Apollo last August.

Roadside equipment in the district has been deployed to monitor the traffic flow, and relevant data will be transmitted to a "smart brain" for traffic light optimization based on big data and artificial intelligence algorithms.

A series of traffic lights along Kaichuang Avenue, Kaitai Avenue, Kexue Avenue, Kexiang Road, Chuangxin Avenue and Jiulong Avenue are coordinated to allow continuous traffic flow over several intersections in one main direction. On average, times a vehicle encounters a red light are cut from three-four to zero-one, and the travel time along the six artery roads is cut by 25 percent.

In addition, the time wasted when there are no vehicles at the road intersection during green light is reduced by 21 percent.

As of now, traffic lights at 32 intersections in Guangzhou Science City and China-Singapore Guangzhou Knowledge City have been automatically adapted to road conditions, accounting for 57 percent of the total and will be integrated in more areas. 

Moreover, the smart transport project also prioritizes the travel of tramways at intersections, with the time for each trip cut by around 28 percent.
