The anti-noise tunnel is a cost efficient alternative to decrease noise from traffic and increase the use of attractive areas as well as increase life quality for people in areas disturbed by traffic noise. It is a cheap and fast method to build surface tunnels that decreases traffic noise.
By encapsulating the traffic and the noise, new areas can be exploited; alternatively the value of existing property can increase. For the common good, recreational areas can be less disturbed by traffic noise and there will be a possibility to build fast track bike lanes along densely trafficked roads which makes the bike a more competitive means of transportation for commuting.
The solution combines existing solutions to build cheaply and quickly, but still sustainably, with a new material with good noise qualities. During the construction time the disturbances on the traffic will be limited and if conditions change, the construction can be moved.
Other positive aspects are that the outside of the tunnel can be used for solar energy solutions through thin-film solar cells. Green walls and urban gardens can be placed on/close to the tunnel and increase the visual attractiveness as well as making use of the urban space. The aesthetic impression can be improved by printing patterns that contribute positively to the area on the outer cover and using colours that are fitting. U&We leads Step 1 of the project.
