India's urban centres are slowly but surely getting congested with the exponential rise of vehicles on the road. Especially in areas such as old market areas, tourist destinations, bus stands, railway stations and main business districts, life is becoming unhealthy and unsustainable, with traffic causing a great waste of time, energy and fuel. Traffic congestion is also causing pollution levels to rise in Indian cities. Shortage of sufficient parking space contributes to this sorry state of affairs.
