People over the world use transportation to transport to other places with ease. As transportation means the use of vehicles for the movement of passengers, it is of course a useful object to people due to its fastness and autonmatic characteristic. Especially, to go to Busan from Seoul which distance is like 5 km, in a very long length far distance. The time passes continously and the scientific technology keeps developing making a better and a greater machinery. The speed gains to high-tech balloon and these days the safety is the most important qualification for making public things infrastructure. The production that has both great quickness and stability makes the best transportation and in Korea. Makers attempt hard to have a wonderful invention for people's lives. I would like to introduce a subway, the greatest transportation in Korea.
First, it is nearly related to fastness of it. As it carries a lot of people, totally greater than 100, it should be steady. And, for a businessman or the one who is busy with the at work, this is organized with a strong engine enough to move fast carrying many passengers. Time is gold. There is a famous proverb that imposes the importance of time. Even if the price is in average and when someone is in emergency or they are supposed to move in a hurry, it is a wise choice to use a subway.
Secondly, it is about the safety. In physics, most people want to live longly at most and though the transportation has many advantages and is helpful, but if it is not safe and has the lacking of tools, they tend not to take that transportation as this is able to leads to the danger of a life. Many citizens use andd ride on it. and If there goes even a little mistake and causse an accident, immediately, they will go to the another world. So, we don't want to have a painful of the death and but to live forever.
Until here, I have talked about the two main things that should be put into a public transportation. Fastness and quickness are very important and essential when producing a ceratin thing. These two if combined together and would a subway become a great vehicle for the workers or humans passengers.
