According to reports, in Xiong’an New District, Hebei, China, there is a set of the most important “smart highway” demonstration roads in the country, Jingxiong Expressway. There are white smart light poles every 40 meters on both sides of the road, integrating intelligent sensing, smart lighting, and energy saving. Consumption reduction ability.
The local traffic police deployed an intelligent information control system, allowing vehicles to pass through 12 traffic light intersections in one go, achieving green light traffic all the way.
In fact, there is a magical “green wave speed” regarding the green light all the way, which means that the speed of the vehicle is consistent with the green wave speed of the signal light.
Green wave speed is also called green wave belt, wave speed control, and multi-intersection signal linkage. It is mainly designed in sections with many intersections in order to make the signal timing more accurate and scientific.
Currently, the main roads in all cities have green wave speed controls behind them, with speeds uniformly fluctuating between 50 and 60 kilometers per hour.
However, due to traffic conditions, it is understandably difficult to achieve the green wave speed. With smart transportation in the future, it may no longer be a dream to have a green light at any time.
