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...
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...
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...
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...
Smooth traffic flow as one of the most important factors for safety increase in road transport
external costs traffic flows intelligent transportation systems (ITS) ITS technologies communication systems
2010/11/2
The elimination of the connection between the increase of transport and economical growth has been the main aim of transport policy of the EU for a few years, which has not been accomplished yet. The ...
