In this paper, we propose an edge-based shortest path cache that can efficiently handle large-scale path queries without needing any road information. We achieve this by designing a totally new edge-based path cache structure, an efficient R-tree-based cache lookup algorithm, and a greedy-based cache construction algorithm. Experiments on a real road network and real POI datasets are conducted, and the results show the efficiency of our proposed caching techniques.
