Affordance-based individuation of junctions in Open Street Map

open access: yesJournal of Spatial Information Science, 2012
We propose an algorithm that can be used to identify automatically the subset of street segments of a road network map that corresponds to a junction. The main idea is to use turn-compliant locomotion affordances, i.e., restricted patterns of supported ...

Urban Road Network Data

open access: yes, 2016
Tool and data set of road networks for 80 of the most populated urban areas in the world. The data consist of a graph edge list for each city and two corresponding GIS shapefiles (i.e., links and nodes).Make your own data with our ArcGIS, QGIS, and ...

Toward Native Explainable and Robust AI in 6G Networks: Current State, Challenges and Road Ahead [PDF]

open access: yes, 2022
6G networks are expected to face the daunting task of providing support to a set of extremely diverse services, each more demanding than those of previous generation networks (e.g., holographic communications, unmanned mobility, etc.), while at the same ...

Sensor Networks For Smart Roads [PDF]

open access: yesFourth Annual IEEE International Conference on Pervasive Computing and Communications Workshops (PERCOMW'06), 2006
This paper proposes the use of a wireless sensor network of "cat's eye" augmented with embedded processing, communication, and sensing capabilities to monitor vehicle behaviour on augmented roads. The primary goal of the system is to provide drivers with early warning of potentially dangerous situations that may arise.

Efficient Geo-Computational Algorithms for Constructing Space-Time Prisms in Road Networks

open access: yesISPRS International Journal of Geo-Information, 2016
The Space-time prism (STP) is a key concept in time geography for analyzing human activity-travel behavior under various Space-time constraints. Most existing time-geographic studies use a straightforward algorithm to construct STPs in road networks by ...

Topometric localization on a road network [PDF]

open access: yes2014 IEEE/RSJ International Conference on Intelligent Robots and Systems, 2014
Current GPS-based devices have difficulty localizing in cases where the GPS signal is unavailable or insufficiently accurate. This paper presents an algorithm for localizing a vehicle on an arbitrary road network using vision, road curvature estimates, or a combination of both.

Opportunistic fleets for road event detection in vehicular sensor networks

open access: yes, 2022
High mobility and variable road surface condition brings big challenges for road event detection by using vehicular sensor networks (VSNs). VSNs are data-centric networks, so that the efficient collaborations among opportunistic topology structure in the
