The document presents information on sky bus technology, which is proposed as an improved transportation system to address traffic issues in cities. Sky bus would move people and cargo along existing roads at 100 kmph, without requiring additional road space, at a lower cost than underground metro systems. It consists of standard railway coaches running on an elevated track system of skyways, sky bogies, sky coaches, and sky stations. While a prototype sky bus system was tested in India, it had an accident in 2004 and has not been further adopted. The technology aims to provide a safer, more affordable, and pollution-free transportation option for urban areas struggling with traffic.
