Half of the global population now lives in cities. World's urban population is estimated to be doubled by 2050. Cities around the globe are already under pressure of rapid urbanization as 1.4 million people migrate to cities each week in search of employment, for better living and for education. Indian cities are also expanding in area and becoming more crowded. Urbanization in India has gathered pace and planners are foreseeing rise in urban population to 40% by 2021 which is 31% as per 2011 Census. Problems have already started surfacing as urban infrastructure is lagging way behind actual needs. Public transport services are chaotic and most new cities are still struggling to set up a working public transport.

World Bank and World Resources Institute (WRI) also believe that smart cities and urban mobility are keys to a sustainable future.
