Collaborative Map Matching in Nav2Nav [PDF]
Proceedings of the 7th International Conference on Collaborative Computing: Networking, Applications and Worksharing, 2011 Although in-car navigation systems are becoming commonplace, cars travelling in urban canyon areas still suffer from poor positional accuracy and limited visibility of GPS satellites due to signal blockage. As a result, map matching accuracy and navigation performance may not reach the required level for many applications.

Online Particle Smoothing With Application to Map-Matching [PDF]
IEEE Transactions on Signal Processing, 2022 We introduce a novel method for online smoothing in state-space models that utilises a fixed-lag approximation to overcome the well known issue of path degeneracy. Unlike classical fixed-lag techniques that only approximate certain marginals, we introduce an online resampling algorithm, called particle stitching, that converts these marginal samples ...

Research on Multi-sensor Fusion Localization for Autonomous-rail Rapid Tram
Kongzhi Yu Xinxi Jishu, 2022 Traditional positioning methods, such as GNSS (global navigation satellite system) and location base service, have large positioning error when applied in complex traffic scenarios such as like tunnels buildings and viaducts.

Map-Matching Using Shortest Paths [PDF]
ACM Transactions on Spatial Algorithms and Systems, 2018 We consider several variants of the map-matching problem, which seeks to find a path Q in graph G that has the smallest distance to a given trajectory P (which is likely not to be exactly on the graph). In a typical application setting,

Map-matching Algorithm for Large Databases [PDF]
Journal of Navigation, 2015 This article proposes a batch-mode algorithm to handle the large databases generated from experimentations using probe vehicles. This algorithm can locate raw Global Positioning System (GPS) positions on a map, but can also be used to correct map-matching errors introduced by real time map-matching algorithms.

Concurrent and robust topological map matching [PDF]
Proceedings of the 20th International Conference on Advances in Geographic Information Systems, 2012 Offline map matching is a process of associating a sequence of GPS location readings measured with a device held by a traveling user, to the real-world roads that were presumably traveled by the user. The main goals in map matching are (1) to provide an association which is as accurate as possible with respect to actual traveled roads, and (2) to ...

Geomagnetic/inertial navigation integrated matching navigation method
Heliyon, 2022 The accuracy of an a priori geomagnetic reference map is a significant constraint on the geomagnetic matching navigation method. Especially when the aircraft enters an unknown environment, it is impossible to accomplish the navigation task using ...

Map Matching for Urban High-Sampling-Frequency GPS Trajectories
ISPRS International Journal of Geo-Information, 2020 As a fundamental component of trajectory processing and analysis, trajectory map-matching can be used for urban traffic management and tourism route planning, among other applications.

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Children with acute lymphoblastic leukemia (ALL) are at risk of severe outcomes from SARS‐CoV‐2 (SCV2). In the post‐pandemic context, where most children have been infected with SCV2, there are limited data on whether vaccination remains beneficial in children with ALL.
