Have you ever worried about missing a bus? Sure you have. That's why Ismail Uddin decided to solve this problem and made London Bus Ticker for vehicles outfitted with GPS module. Our congratulations, Londoners!

Via Science Exposure:

If you’ve ever had to wait for a bus in London, there’s a good chance you’ve used a TfL live bus arrivals ticker. If you haven’t, all you need to know is that it’s a rather long LCD screen that shows live arrival times for the next two buses at the bus stop. This is possible due to every bus in London being outfitted with a GPS module, allowing them to be tracked in realtime and enable arrival predictions.
In today’s tutorial, we’ll be recreating the live bus arrivals ticker using a Raspberry Pi and a cheap Hitachi 16×2 LCD character display.

Requirements

• Raspberry Pi (any model will do)
• 16×2 LCD with a Hitachi HD44780 controller
• 1K Ohm minimum resistor (depending on your LCD module)
• Potentiometer
