Green Wave

This exhibit consists of a push rod, a speed display screen, a monitoring screen, and a graphic version. In a city road with one horizontal and four vertical roads, visitors pushes the push rod to control the real-time speed of vehicles on each section, observes the interval between traffic lights, and controls the traffic on the monitoring screen to form a smooth "green wave" in the road network. The monitoring screen is combined with the speed display screen, and the vehicle operation mode on the screen will be simulated through algorithms such as driving, traffic congestion, intersection traffic, etc., achieving WYSIWYG and synchronously providing real-time feedback on road conditions. This exhibit aims to introduce the principle of green wave belts to the public and popularize the influencing factors of green wave belts, such as traffic lights, intersection distance, vehicle flow and direction, vehicle speed, intersection structure, vehicle type, special circumstances, etc. Viewers can understand the principles of traffic control, cultivate awareness of traffic planning, learn optimization strategies and assistance through interactive experiences. It can also encourage them to pay attention to urban traffic and participate in traffic planning and improvement.

The unit is designed for unsupervised public use: controls are recessed or shielded, moving parts are enclosed, and the interface is operable by a child of about six with no instruction. Where a screen is used, the language can be switched without changing the hardware, and the content can be replaced on site.

The green wave band can be understood as a relay of green lights on a road. The system will coordinate the timing of multiple signal lights along the route based on the distance between road sections, traffic flow, and intersection spacing. When the vehicle travels at the recommended speed on the screen, there is a chance to pass through multiple intersections in a row when encountering green traffic, reducing waiting and congestion caused by parking and starting. This can not only improve traffic efficiency, but also reduce fuel consumption and emissions, making travel smoother and more environmentally friendly.
