Three general types of bus arrival information system in Korea

⚠ Warning : I'm not good at English

 Knowing bus arrival is very useful.

 If you know when a bus arrives, you can spend time at a bus stop properly and know arrival time of destination more exactly.

 Plus Knowing arrival get you stabilized psychologically.

 In Korea, there are three general types of bus arrival information system.
This is first type. It has lots of functions, for example knowing a bus route with buttons on a machine and where are buses in detail.

 Many softwares need to operated those functions for that reason this system causes errors frequently and needs lots of money to set up.
 And if there is backlight, you will be hard to use that arrival system because of reflecting.

 This is Second type. It is simpler that upper thing but it also causes errors frequently
, because it want to tell arrival information in detail and all information at once.
 And also it has a problem of reflecting.

This is Third type as well as very general type.

 It only tells remaining time and is displayed by LED.

 I thinks that is perfectly enough.

 Other functions are overlapped and unnecessary.

**Lastly

Using complicated system isn't so bad because it just a try but the most important thing is

realizing problems of complication and considering this case 

when city governments try to set public facilities up.

I wish they realize that less is more.
