A Real-Time Spatial Index for In-Vehicle Units
Magnus Lie Hetland, Ola Martin Lykkja · arXiv (Cornell University) · 2014
We construct a spatial indexing solution for the highly constrained environment of an in-vehicle unit in a distributed vehicle tolling scheme based on satellite navigation (GNSS). We show that an immutable, purely functional implementation of a high-fanout quadtree is a simple, practical solution that satisfies all the requirements of such a system.
