Four other Chinese cities, Nanyang, Shenyang, Tianjin, and Zhoukou, had also signed contracts for pilot projects involving the construction of test tracks beginning in 2016.
[8] The idea of Transit Elevated Bus was proposed in 1969 by two American architects, Craig Hodgetts and Lester Walker, as a public transport concept called the "Bos-Wash Landliner".
[9] Later, another version was designed by Shenzhen Hashi Future Parking Equipment Company (深圳華世未來泊車設備有限公司), and the concept, known as 3D Express Bus (立体快巴) at the time, was unveiled at the 13th Beijing International High-tech Expo in May 2010.
[5] In China there are four main modes of public transportation: subway, light rail, bus rapid transit (BRT), and normal buses.
[4] At the time of the 2016 unveiling of the scale model, it was reported that a prototype would be deployed by mid-2016 in Qinhuangdao, a coastal city about 300 km (190 mi) east of Beijing.
[5] Song Youzhou, the designer of the bus, said in an interview that other four Chinese cities, Nanyang, Shenyang, Tianjin, and Zhoukou, have also signed contracts with his company for pilot projects involving the construction of hundreds of kilometres of tracks beginning in 2016.
[22] Critics of the project when the concept was unveiled in 2010 have questioned whether the hovering bus could interact safely with other vehicles, particularly when drivers manoeuvre to change lanes.
Critics had also argued that the tracks would require relatively straight roads not found in many older urban areas, and that the overhead boarding stations that the bus needed would take up too much space.
Lanes for the elevated bus would be limited to passenger vehicles no higher than 2.2 m (7 ft 3 in), and the buses are designed to meet zoning and bridge height regulations in each city.
[3] In 2016 Mr. Song said to Chinese media that he had arranged to have Shanghai Jiao Tong University's Institute of Automotive Engineering to assess the feasibility of the TEB design.
"It is true that two researchers from Laboratory of Traction Power had a feasibility meeting with the company", the deputy director of the lab Wang Kaiyun said, "but the comment on it was 'suspicious' (悬).
[8] In July the bus was removed and police arrested 32 individuals for "illegally raising funds to finance the TEB" after complaints from 72 investors were filed with them.
