Breath station / communal facilities

In order to improve this situation, a tail gas absorption device is installed in the side of each bus station step. In this way, the absorption device can absorb the exhaust immediately as soon as it is discharged, while passengers have not to put up with the harmful exhaust emissions. As known, buses would like to generate a large amount of exhaust when it stops and starts. Passengers waiting for a bus in the platform have to breathe the exhaust emissions, which is harmful to health over time. If this issue of exhaust emission cannot be handled in time, a lot of air problems will also emerge, thus further damage to health.
