Explain how transport forecasts are made and why?
Transportation forecasting is the process of estimating the number of vehicles or travelers that will use a specific transportation facilityin the future.

the forecasts can basis on the figure,data and trend on transport. For example, the number of railway line prepare to use, the number of passengers satisfy by airport, or the number of ships calling on a seaport. To do transport forecasting, The first step is collection of data on current traffic. together with data on population, employment, cost etc. Feeding data on future population, employment, etc.

Explain the main ways in which transport sector can be described through the data.

For example, we have data which shows the how does consumer think about the comfortable of take bus, if there are more than 50% consumer think it is not good enough, the manager of bus company may make a forecast to solve this problem. In the opposite if the data shows there is more than 50% consumer think it is good, the manager of bus company will make a forecast which is how to keep it.

Outline economic of scale and application to transport.
Economies of scale: where average cost falls as production increases. They are happening because larger firms are able to lower their unit costs.
application to transport relevant the regulation and the transport market, for example barrier to entry, and one reason
of it is to entry a transport market should have licence from government.
