Shortest Path Queries by Labeling for Paths with Pruning in Road Networks
Yuki Kawata, Takuya Akiba, Yoichi Iwata (Univ. of Tokyo) COMP2013-20
Abstract (in Japanese) (See Japanese page) 
(in English) Shortest-Path problem is a fundamental problem in road networks and a lot of methods are proposed. In the labeling approach, we can answer queries extremely fast. The labeling approach precomputes and stores distance labels to each vertex and answers queries by using these labels. In previous labeling methods, we precompute labels for vertices. However, we propose a new labeling method such that we precompute labels for paths. We demonstrated that our method can precompute labels efficiently and answer queries in comparable time to previous labeling methods through experiments.
