Last year, the sound insulation panels on both sides of the Shanghai elevated road were not transparent;
This year, the vehicle was on the elevated road in Shanghai, and the sound insulation panels on both sides added a middle transparent part.

Let alone how much it will increase, but from the perspective of human nature, it is very desirable. Driving drivers can increase their horizons and reduce the pressure and visual fatigue caused by the sound insulation board, greatly reducing the probability of car accidents. For the Residents next to the elevated road (especially high-profile residents), pushing the window is not only an annoyance caused by the roar of sound, but also a view of the flowing car scene (especially at night ). Therefore, it can bring some benefits to drivers and residents.

Therefore, in economics, public goods have their own characteristics. The consumer's ability to accept public goods must be taken into account.
