ELI5: Explain Like I'm 5

Passenger information system

A passenger information system is like a magic box that tells you when and where to catch your bus, train, or other form of transportation.

This box is like a teacher who knows everything about the transportation system and can tell you all about it. It has a special power that allows it to track transportation vehicles with the help of a GPS system, which stands for "Global Positioning System." GPS helps the box know where the transportation vehicles are and how long they will take to reach your location.

When you go to the bus stop or train station, you can look at a screen that has all sorts of information about the different transportation options available. This screen is part of the passenger information system. It tells you when the next train or bus is coming and where it is going. The screen also gives you other important information, such as the expected arrival time, the route map, and the fare.

The passenger information system can also talk to you, like a kind robot friend. It can use speakers to announce arrival times and departure times, so you can always stay informed even if you are not looking at the screens. Most of these announcements are made in multiple languages, so everyone can understand them.

In summary, the passenger information system is like a smart box that tells you when and where your transportation is arriving, where it is going, how long it will take, and how much it will cost in a really easy-to-understand way. It's like having a personal teacher or robot friend who knows everything about transportation and never gets lost!
