ABSTRACT
Most Indian cities have expanded after 1960 and all have planned for multiple business districts. Changes in car technology are deciding how people behave in Indian cities. Enough has been written on the deleterious effects of vehicle emissions on the health of urban citizens. Senior citizens are reported to live lonelier lives on wide, busy and noisy streets, and suffer greater health problems with elevated blood pressure. This is partly because they cannot cross the street easily and lose half the population for socialisation, shopping and other human needs. The modes of travel used by people in cities are decided by a balancing of economic compulsions, comfort and safety. Safety on access trips also emerges as a very important issue, especially for women and children. Unless the walking trip is safe from accidents, harassment and crime, people avoid using public transport. The transportation system is driven largely by positive feedback, encouraging people to drive longer distances at higher speeds.
