Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Sparse Tensor Optimization Approaches for Traffic Flow Prediction, Anomaly Detection and Video Surveillance
交通流预测 异常检测 视频监控 稀疏张量 优化方法
2023/4/13
Tensor-based modeling and computation emerge prominently with urgent demands from practical applications in the big data era. With the intrinsic sparsity in real data sets and the dimensionality reduc...
UNDERSTANDING URBAN TRAFFIC FLOW CHARACTERISTICS FROM THE NETWORK CENTRALITY PERSPECTIVE AT DIFFERENT GRANULARITIES
taxi trajectory granularity network centrality
2016/7/8
In this study, we analyze urban traffic flow using taxi trajectory data to understand the characteristics of traffic flow from the network centrality perspective at point (intersection), line (road), ...
An Updating Method of Geospatial Data Based on Traffic Flow Analysis
Network GIS Traffic Flow Data Updating
2015/10/12
The paper proposes a new kind of objected-oriented method of updating geospatial data, that is different from the previous “bottom
up” or “top down” updating methods. Through weighted directed graph...
APPLICATION OF AERIAL VIDEO FOR TRAFFIC FLOW MONITORING AND MANAGEMENT
Remote sensing data aerial data source data acquisition image processing remote sensing data monitoring automatic image processing
2015/5/13
Researchers at the University of Arizona are investigating the potential of remotely sensed data, using aerial
video, to enhance existing data sources and therefore to improve traffic management. Thi...
Exploiting Satellite Focal Plane Geometry for Automatic Extraction of Traffic Flow from Single Optical Satellite Imagery
Optical Satellite Data Focal plane assembly Traffic detection Moving objects detection
2014/12/4
The focal plane assembly of most pushbroom scanner satellites is built up in a way that different multispectral or multispectral and panchromatic bands are not all acquired exactly at the same time. T...
Influence of Traffic Flow Patterns on Air Quality inside the Longest Tunnel in Asia
Hsueh-shan Tunnel Air pollutants Traffic flow Piston effect
2016/3/28
The long tunnel is a fixed, semi-closed environment where excessive concentrations of air pollutants are easily
accumulated. This can potentially have a serious affect on drivers' health, especially ...
Analysis of kinematic waves arising in diverging traffic flow models
Kinematic wave models diverging traffic Riemann problem supply-demand space
2010/12/13
Diverging junctions are important network bottlenecks, and a better understanding of diverging
traffic dynamics has both theoretical and practical implications. In this paper, we first
introduce a c...
Fokker-Planck Asymptotics for Traffic Flow Models
Traffic Flow Modeling Fokker–Planck Equations
2010/12/6
Starting from microscopic interaction rules we derive kinetic models of Fokker–Planck type for vehicular traffic flow. The derivation is based on taking a suitable asymptotic limit of the correspondin...
Modelling heterogeneous traffic flow on upgrades of intercity roads
upgrade power-to-weight ratio acceleration rates heterogeneous traffic simulation speed–volume relationships speed–distance profiles
2010/10/29
The effect of an upgrade and its length is very significant for traffic flow characteristics. Road traffic in developing countries like India is highly heterogeneous comprising vehicles of wide rangin...
Calibration of the Particle Density in Cellular-Automaton Models for Traffic Flow
Particle Density Traffic Flow Cellular-Automaton Models
2010/4/2
We introduce density dependence of the cell size in cellular-automaton models for traffic flow, which allows a more precise correspondence between real-world phenomena and what observed in simulation....
Mathematical modelling of network traffic flow
traffic flow intersection modelling traffic flow regulation vehicle
2010/11/1
The article describes mathematical models of traffic flows to initiate different traffic flow processes. Separate elements of traffic flow models are made in a way to be connected together to get a si...
Characteristics of ant-inspired traffic flow：Applying the social insect metaphor to traffic models
Characteristics ant-inspired traffic flow social insect metaphor traffic models
2010/3/18
We investigate the organization of traffic flow on preexisting
uni- and bidirectional ant trails. Our investigations comprise a theoretical
as well as an empirical part. We propose minimal models of...
Interdependence of noise and traffic flow
traffic flow noise statistics regression distribution
2010/11/1
Traffic flows in cities, especially in city centres, are intensive and uneven, moreover, registered noise levels exceed allowable limits. Noise levels have been measured at K. Mindaugo ave. and Bir...
Determination of traffic flow parameters in different traffic flow interaction cases
traffic flow kinetic theory modelling characteristic method
2010/11/1
Modelling of straight road section consisting of one traffic line gives the opportunity to simulate “follow the car” system. In general it looks like a line of vehicles, going one after another. Kinet...
