Auto-rickshaws play an important role in urban mobility in most Indian cities.  EMBARQ India’s analysis on the size of the auto-rickshaw market in select Indian cities, based on government records, indicates that Tier I cities in India (with population greater than 4 million) typically have more than 50,000 auto-rickshaws, while Tier II cities (with population between 1 and 4 million) have between 15,000 and 30,000 auto-rickshaws.  Auto-rickshaws, thus, constitute a significant share of the vehicle mix in cities.  Further, auto-rickshaw density in relation to city population varies from around 4 to 16 auto-rickshaws per 1000 people in Tier I and II cities.
