A “green wave” occurs when a series of traffic lights are coordinated to allow continuous traffic flow over several adjacent intersections. The vehicles travelling along with the green wave (at a certain speed) will see a progression of green lights without having to stop at intersections.

The city has already had 20 main streets that have embraced the green waves, scattering in the second, third, fourth and fifth ring. This year, the city’s Second Ring Road will see a network of green wave streets.

Additionally, citizens can scan the QR code on the cases of traffic signals for repairs if the signals fail to work. Maintenance personnel will arrive in 20 minutes after being informed about it.
