The reporter recently learned from Beijing Investment Transportation Company that since the Daxing Airport Expressway was officially opened on July 1, last year, the total traffic volume has reached 17.44 million. In the past year, the high-speed “smart street lights” have saved about 400,000 kWh of electricity, with a comprehensive energy-saving rate of 30%.
Citizens drive to the Daxing Airport Expressway at night, and they will find that the street lights along the way are bright and starry.
