If your local bus stop has 4 or fewer bus routes, the LED display could show all the information at once, rather than scrolling through all the bus times for the next 30 minutes, most of which no one cares about.
Suggested layout:
123 Destination W 0, 3, 8.. mins
041 Destination X 2, 6, 14.. mins
101 Destination Y 0, 7, 13.. mins
202 Destination Z 2, 8, 16.. mins
Then you can see all the information at once. If there are more routes you could scroll through them.
