Your question is very vague. In Trucking, it is to move products from manufacturing to sales outlets. I really do not know any other way to answer this without further comments on your part.
Why Do We Need Transportation?
Transport in the Republic of India is an important part of the nation's economy. With a land area of 3,287,240 km2 (1,269,210 sq mi) and an estimated population of 1,028,737,436, transport in India is both a necessity as well as a convenience. Since the economic liberalisation of the 1990s, development of infrastructure within the country has progressed at a rapid pace, and today there is a wide variety of modes of transport by land, water and air. However, the relatively low GDP of India has meant that access to these modes of transport has not been uniform. Only around 10% of households own a motorcycle (about 102,873,744 people). Cars are owned by the wealthier few — around 0.7% of households owned one in 2007 (about 7,201,163 people).Public transport still remains the primary mode of transport for most of the population, and India's public transport systems are among the most heavily utilised in the world. India's rail network is the longest and fourth most heavily used system in the world transporting over 6 billion passengers and over 350 million tons of freight annually.
