What about a sort of reverse 'bread-crumb' solution? A way for the pilot(s), once on the ground to be actively shown the way to go. It seems that when an airplane is on the ground, you need three pieces of information: who they are, where they are at a given point in time, and where they need to end up. From that you can calculate everything else and make dynamic adjustments along the way. Let's assume who they are can be identified through their transponder code. Where they are can be established by placing them at a known spot, say a given taxiway with a bright green 'COME HERE' light. Since runways are essentially serialized pipes and one airplane at a time can be on them, you only need to time it so as soon as airplane A lands, the proper taxiway is lit for that plane and that one alone and as soon as they cross the threshold, the light turns off, ready for the next arrival. Where they want to go depends on whether they are a big plane with a fixed pre-determined destination ...
