China’s Huawei Develops Smart Roads That Talk to Driverless Cars

  • Tech giant seeks new growth areas amid phone-network headwinds
  • At China test site, self-driving bus is guided by surroundings

The abstract concept of connected vehicles becomes easier to grasp at a test site in eastern China.

On a four-kilometer (2.5-mile) road in the city of Wuxi in Jiangsu province, a self-driving bus travels back and forth, making stops, swerving past obstacles, accelerating and decelerating, based on information it constantly receives from its surroundings. Embedded in the road, traffic lights, street signs and other infrastructure are sensors, cameras and radars that talk with the vehicle.
