The 'Transit Elevated Bus' is a conceptual design for a transportation solution for China's busy roads. The bus is designed to be elevated off the ground with a tunnel shape that is able to physically move overtop of other cars. In other words, the bus is a moving tunnel providing seating for commuters on a storey platform. The tunnel shape ensures that the addition of more transportation to the city roads won't further clog up traffic.
The bus provides transportation to consumers that is elevated above ground, so that the bottom half of the bus remains hollow and can move over other cars as if they are going through an archway.
The shape of the 'Transit Elevated Bus' leads it to be ideal for straight line travel due to the massive size and length of the bus -- making it more difficult to circle around corners.
