The red and green LEDs on the ceiling are attached to sensors placed above each parking space in the deck. The sensor determines if the space beneath it has a car in it or if it is empty, and turns on the appropriate indicator light... red means occupied, green means available. On the main driveway through the deck, there are also LED signs at the intersections with each row of parking spaces that tell you which rows have spaces available and which are full. You can easily look down any row (without actually turning down it) and see where the empty spaces are. The Planned Route
This is as close to "final" as the planned route is likely to get... I don't intend to do any more updates to it. If it changes, I'll mention it in future posts. All but a few of the green lines represent flight segments. Looks like we have a lot of reading in store...

The picture, such as it is, was taken inside the parking deck at the Johannesburg airport.

I agree, that is a great idea. Adrian
