Road-For road transport,generally it is very convenient and efficient, because it is provide the door to door service. For example delivering goods by truck. It is extensively used in retailing and where 'just in time' are required it is not always the most sustainable mode and has poor public image
Rail- For rail transport, it is convenient can efficiency as well, but it more suit to middle and long distances. on another hand, it more suit to container traffic over long distance. there are interchange limitations for certain types of potential traffic. The capacity of rail is big.
Air- For air transport the speed s very high and it is over long distance and it is very efficiency, therefore, for business and travel, air transport is a good choice. Clearly relevant for transporting time sensitive cargo such as mail and certain types of food products, but is cost a lot. However, it is the least sustainable mode because there are few realistic substitutes.
Sea-For sea transport it is very suit to bulky good. for example oil and containers, can be moved over longer distances where speed is not an important consideration. For example when you send letter, you will choose send it by ship or by air which means normal or quicker.
Explain why transport is derived demand.
Because transport as a service or function is not demand purely for what it it, but for what it can do. people will choose the transport because it can satisfy what are they want to do. for example a person buy clothes on line if she want to get this clothes she must choose a way to post it. therefore she can choose post by quicker way(airway) or normal way(ship).
Explain how to measure transport demand.
Price,price charge is very important , but it depends on the elasticity and different transport modes.
price on substitutes,the demand will change with the price change in substitutes. however we need concern about demand elasticity as well.
income , higher income in passenger will stimulate them purchase more on transport. however it depend on the elasticity and current situation.For example if the interest rate is high they may saving more instead of purchase it on transport.
quality, high quality will help to increase the demand, but if the price is so high, the demand may decrease so it depends.
