A Hub-Based Labeling Algorithm for Shortest Paths on Road Networks

Abstract. Abraham et al. [SODA 2010] have recently presented a the-oretical analysis of several practical point-to-point shortest path algo-rithms based on modeling road networks as graphs with low highway dimension. They also analyze a labeling algorithm. While no practical implementation of this algorithm existed, it has the best time bounds. This paper describes an implementation of the labeling algorithm that is faster than any existing method on continental road networks.
