Practical shortest path finding algorithms need minimized search-space for performing these computations by keeping these data in the computer’s conventional memory. The hierarchical pruning methods for minimizing the search-space to support real-road shortest algorithms are more suitable for connecting multiple cities and towns via highways. This study is to present a new suitable pruning method for intra-city shortest path finding, called elliptical pruning to bring the geo-tagged nodes and edges in to the memory for the subsequent shortest path finding process for the complex city road-transport networks.} }
