With the characteristics of wide influence range, long duration, and deep pollution degree, road traffic noise has become the main environmental problem in road traffic. According to the overview of road traffic noise pollution in China, combined with the development of acoustic metamaterials and electroacoustic technology, the technical characteristics, application scope, and research and development direction of noise control measures such as sound barriers, low noise pavements, ventilated soundproof windows, noise reduction forest belts, and intelligent control are introduced. The advantages and disadvantages of sound barriers made with typical structures and materials and low noise road surfaces are reviewed, as well as their noise reduction effects. Vegetation types that can be used as noise reduction forest belts in different regions of China are provided. And the next development direction of road traffic noise control technology is pointed out from several aspects, such as low noise pavement acoustic design, application of audio and information technology, recycling of green and low-carbon materials, creation of road acoustic landscapes, environmental noise and sustainable development, to support the construction and development of peaceful transportation and comfortable living environments.
