Intelligent route planning on large road networks with efficiency and privacy
J. Parallel Distributed Comput., 2019When using Location-Based Services (LBS), intelligent route planning becomes crucial to improve service quality and user experience. The state-of-the-art G-tree structure enables efficient route planning on large road networks, but lacks usability and ...

The Evolution of Quantum Key Distribution Networks: On the Road to the Qinternet
IEEE Communications Surveys and Tutorials, 2022Quantum key distribution (QKD) constitutes a symmetric secret key negotiation protocol capable of maintaining information-theoretic security. Given the recent advances in QKD networks, they have evolved from academic research to some preliminary ...

Querying Shortest Paths on Time Dependent Road Networks
Proceedings of the VLDB Endowment, 2019For real-world time dependent road networks (TDRNs), answering shortest path-based route queries and plans in real-time is highly desirable by many industrial applications.

Route-preserving Road Network Generalization
Proceedings of the 28th International Conference on Advances in Geographic Information Systems, 2020We investigate a data-driven approach for road network generalization, where the input is a road network and a collection of routes or trajectories on these roads. The aim is to select a subset of the road network in which many routes of the collection are fully preserved.

The availability of large graphs that represent huge road networks has led to a vast amount of experimental research that has been custom-tailored for road networks. There are two primary reasons to investigate graph-generators that construct synthetic graphs similar to real-world road-networks: The wish to theoretically explain noticeable experimental

Stochastic Weight Completion for Road Networks Using Graph Convolutional Networks
IEEE International Conference on Data Engineering, 2019Innovations in transportation, such as mobility-on-demand services and autonomous driving, call for high-resolution routing that relies on an accurate representation of travel time throughout the underlying road network.

Alternative routes in road networks
ACM Journal of Experimental Algorithmics, 2010We study the problem of finding good alternative routes in road networks. We look for routes that are substantially different from the shortest path, have small stretch, and are locally optimal. We formally define the problem of finding alternative routes with a single via vertex, develop efficient algorithms for it, and evaluate them experimentally ...

On connectivity of post-earthquake road networks
Transportation Research Part E: Logistics and Transportation Review, 2019This paper proposes a novel stochastic mathematical framework to investigate the connectivity of road networks impacted by earthquakes. The concepts of “global connectivity” and “local connectivity” are defined and evaluated using percolation theory ...

G*-Tree: An Efficient Spatial Index on Road Networks
IEEE International Conference on Data Engineering, 2019In this paper, we propose an efficient hierarchical index, G*-tree, to optimize spatial queries on road networks. Most existing graph indexes can only support one kind of query, and thus we need to build multiple indexes on a road network to handle ...
