On May 21, a model of a Transit Elevated Bus (TEB), also known as land airbus, debuted at the 19th China Beijing International High-Tech Expo has attracted worldwide attention. Today, the bus comes into being and starts its road test.
The passenger compartment of this bus rises far above other vehicles on the road, allowing cars to pass underneath.
The bus will run along a fixed route, and its passenger compartment spans the width of two traffic lanes. Its undercarriage rides along the edges of the two lanes it straddles and the overall height is 4 to 4.5 m (13.1 to 14.8 ft). Vehicles lower than 2 m (6.6 ft) high will be able to pass underneath the bus, reducing the number of traffic jams caused by ordinary buses loading and unloading at bus stops.
Passengers on board the bus are expected to experience a ride comparable to riding in the upper level of a double decker bus. They will board and alight at stations at the side of the road with platforms at the bus floor height similar to stations of an elevated railway, or via stairs descending through the roof of the bus from a station similar to a pedestrian overpass. The bus will be electrically powered using overhead lines or other roof electrical contact systems designed for it, supplemented with photovoltaic panels, batteries or supercapacitors on board. It will travel at up to 60 km/h (37 mph)
The 3D Express Coach (straddling bus, straddle bus, or tunnel bus) was a proposed new bus designed by Shenzhen Hashi Future Parking Equipment Company back in 2010. It was recognized by Time magazine as the innovation of the year in 2010.
A proposed trial project was to cost about 500 million yuan (~US$74.5 million) to build the bus with a 40 km (25 mi) guideway. This is claimed to be at 10% of the cost of building an equivalent subway, and is estimated to reduce traffic congestion by 20–30%.
