The development of transport infrastructure plays an important role in the growth process through increasing mobility of resources and increasing factor productivity. Transport infrastructure saves time and decreases the cost of transportation, and, thereby, helps both the rich and the poor. Transport development in rural areas strengthens linkages between towns and the countryside. Along with irrigation, it helps adoption of new technology by reducing the cost of inputs and marketing of outputs. It helps the rural poor by increasing their accessibility to schools and health centres and enables them to obtain non-farm employment in far-away places. In India, the share of the transport sector in Gross Domestic Product in 2003-04 was 5.55 per cent (calculated at 1993-94 prices). Roads, Railways, Airports, and Seaports are the infrastructure constituents of Transport Sector.
