RoadAlarm: A spatial alarm system on road networks

Kisung Lee, E. Yigitoglu, Ling Liu, Binh Han, B. Palanisamy, C. Pu
2013 2013 IEEE 29th International Conference on Data Engineering (ICDE)  
In this software system demonstration, we will present the first prototype system of ROADALARM -a spatial alarm processing system for moving objects on road networks.  ...  We argue that spatial alarms should be road network aware as mobile objects travel on spatially constrained road networks or walk paths.  ...  ACKNOWLEDGMENT This work is partially sponsored by grants from NSF CISE NetSE program, SaTC program and I/UCRCs program, an IBM faculty award and a grant from Intel ISTC on Cloud Computing.  ...

Situation Prediction Nets [chapter]

Norbert Baumgartner, Wolfgang Gottesheim, Stefan Mitsch, Werner Retschitzegger, Wieland Schwinger
2010 Lecture Notes in Computer Science  
Situation awareness in large-scale control systems such as road traffic management aims to predict critical situations on the basis of spatio-temporal relations between real-world objects.  ...  Such relations are described by domain-independent calculi, each of them focusing on a certain aspect, for example topology.  ...  For increasing expressiveness, we used temporal axioms mapping object speed to durations (on the basis of domain bindings defining spatial distances), as well as probability axioms mapping orientation  ...

Model-Based Development of Spatial Movement Skill Training System and Its Evaluation

Ayumi YAMAZAKI, Yuki HAYASHI, Kazuhisa SETA
2020 IEICE transactions on information and systems  
In this study, we define spatial movement skill as this ability to associate information like maps and memory with real-world objects like signs and buildings.  ...  Since spatial cognition is always necessary for spatial movement, our aim in this study is to develop a spatial movement skill training system.  ...  It thus appears that spatial movement skills are affected by spatial cognition skills for spatial awareness.  ...

The study on the cognitive spatial structure based on the user's experience - The visual factors on the car navigation map as a basis

Jeongeun Kim, Jongdeok Kim, Hyeyoung Eun
2019 Zenodo  
As a result, to represent the space in the flat interface appropriately, the study for the cognitive spatial structure based on the user's experience is needed.  ...  This study took four steps to conclude the efficient spatial structure with which the user can rapidly recognizes object in the map interface of the car navigation.  ...  But, there are no standards for the consistent spatial structuring of visual factors of a navigation map.  ...

Towards Total Traffic Awareness

Chenjuan Guo, Christian S. Jensen, Bin Yang
2014 SIGMOD record  
Since there is limited room for new roads, smarter use of the existing infrastructure is of essence.  ...  A combination of factors render the transportation sector a highly desirable area for data management research.  ...  For example, the length, speed limit, and toll cost of a road segment may be recorded in digital maps and web pages of road authorities.  ...

RAIST: Learning Risk Aware Traffic Interactions via Spatio-Temporal Graph Convolutional Networks [article]

Videsh Suman, Aniket Bera
2020 arXiv   pre-print
A key aspect of driving a road vehicle is to interact with the other road users, assess their intentions and make risk-aware tactical decisions.  ...  To this end, we propose a novel driving framework for egocentric views, which is based on spatio-temporal traffic graphs.  ...  For each road agent, we have (a) its tracklet r i , and if it exists in frame I t , we have its (b) category label m t i , (c) spatial position p t i in 3D, and (d) scene-aware appearance feature a t i  ...

The New Casper: A Privacy-Aware Location-Based Database Server

Mohamed F. Mokbel, Chi-Yin Chow, Walid G. Aref
2007 2007 IEEE 23rd International Conference on Data Engineering  
While the location anonymizer is implemented as a stand alone application, the privacy-aware query processor is embedded into PLACE; a research prototype for location-based database servers.  ...  Casper consists of two main components; the location anonymizer that blurs the users' exact location into cloaked spatial regions and the privacy-aware query processor that is responsible on providing  ...  The GUI will show the road network map with the exact locations of public data and the cloaked regions for private data.

"Same, Same but Different" A Survey on Duplicate Detection Methods for Situation Awareness [chapter]

Norbert Baumgartner, Wolfgang Gottesheim, Stefan Mitsch, Werner Retschitzegger, Wieland Schwinger
2009 Lecture Notes in Computer Science  
Systems supporting situation awareness typically deal with a vast stream of information about a large number of real-world objects anchored in time and space provided by multiple sources.  ...  As a prerequisite, based on a motivating case study in the domain of road traffic management, an evaluation framework is suggested, which categorizes the major requirements on duplicate detection methods  ...  Road traffic management systems, being responsible for, e. g., improving traffic flow and ensuring safe driving conditions, are a typical application domain for situation awareness.  ...

Effects on Productivity and Safety of Map and Augmented Reality Navigation Paradigms

Kyong-Ho KIM, Kwang-Yun WOHN
2011 IEICE transactions on information and systems  
For the effects on safety, driver's situation awareness of safety-related events on the road was measured.  ...  AR navigation attracted driver's visual attention more frequently than map navigation and then reduces awareness of and proper action for the safety-related events.  ...  And as a result, • (global spatial awareness) may be better for driver's situation awareness of the events occurring on the road. • (two-dimensional exocentric) may be weaker to support route decision  ...
