The Delhi Metro railway is one of the most comfortable means of public transport, according to a study conducted by the Indian Institute of Technology, Delhiusing equipment developed in the United Kingdom. The study used vibration levels experienced by passengers in the metro as a measure of the comfort level and compared it with international standard ISO 2631-4-1997.
According to the study, the vibration inside the train was less than 0·315 metres per second squared m/s2, which is the most comfortable level according to ISO standards.
The study titled ‘Real Time Ride Comfort’, was conducted by Sham Rane, a postgraduate mechanical engineering student of IIT Delhi. It used a device called Potentiometer,developed jointly by Loughborough University UK, and IIT, Delhi, for the first Lime in India.
A group of ten IIT students travelling on the Metro used the potentiometer and by rotation of a knob on the device they did a continuous judgement of their comfortlevel. The data regarding vibration and human responses were then recorded by a central computer and the real ride comfort was assessed.
The study was conducted on elevated and underground sections of all three operational lines of the Delhi Metro and results from all sections were within the most comfortable category. No commuter said the metro ride was uncomfortable.
