Although recent scientific literature focuses on multiple shortest-path (SP) problem definitions for road networks, none of the existing solutions can efficiently answer all the different SP query variations. This work proposes SALT, a novel framework that not only efficiently answers most SP queries but also
k
-nearest neighbor queries not tackled by previous methods. Our solution offers excellent query performance and very short preprocessing times, thus making it also a viable option for dynamic, live-traffic road networks and all types of practical use-cases. The proposed SALT framework is a deployable software solution capturing a range of graph-related query problems under one “algorithmic hood”.
