Multimode Dynamics of the Beijing Road Traffic System
نویسندگان
چکیده
The Beijing road traffic system, as a typical huge urban traffic system, provides a platform for analyzing the complex characteristics and the evolving mechanisms of urban traffic systems. Based on dynamic network theory, we construct the dynamic model of the Beijing road traffic system in which the dynamical properties are described completely. Furthermore, we come into the conclusion that urban traffic systems can be viewed as static networks, stochastic networks and complex networks at different system phases by analyzing the structural randomness. As well as, we demonstrate the evolving process of the Beijing road traffic network based on real traffic data, validate the stochastic characteristics and the scale-free property of the network at different phases. Keywords—Dynamic Network Models, Structural Randomness, Scale-free Property, Multi-mode character

An Analysis Method on Post-earthquake Traversability of Road Network Considering Building Collapse
This study aims at quantifying the influence on the traversability of road network of road network caused by building collapse in earthquake. To this end, an analysis method on post-earthquake traversability of road network considering building collapse is proposed. First, the time-history analysis of seismic response based on the multi-degree of freedom (MDOF) model is performed for regional b...
متن کاملModeling and Density Estimation of an Urban Freeway Network Based on Dynamic Graph Hybrid Automata
In this paper, in order to describe complex network systems, we firstly propose a general modeling framework by combining a dynamic graph with hybrid automata and thus name it Dynamic Graph Hybrid Automata (DGHA). Then we apply this framework to model traffic flow over an urban freeway network by embedding the Cell Transmission Model (CTM) into the DGHA. With a modeling procedure, we adopt a du...
متن کاملEstimation of Road Traffic Mortality in Kurdistan Province, Iran, During 2004-2009, Using Capture-Recapture Method
Background: To reduce traffic injuries in the country, health professionals should have accurate estimates of road traffic deaths. Multiple and sometimes inconsistent statistics presented by organizations in charge create high degree of uncertainty for planners and decision makers. To achieve an accurate estimate, several methods are available. Of them, capture-recapture method ...
متن کاملMethod of Video-Measurements of Traffic Flow Characteristics at a Road Junction
In the theory of traffic flows the main characteristics are: intensity, speed, and density. They make it possible to use hydrodynamic models. In connection with the development of modern highways and road networks, traffic flows behavior is becoming more and more complex and diverse. In particular, the B.Kerner studies have shown that the laminar solution of hydrodynamic models is poorly corre...
متن کاملA Comparison of Traffic Operations among Beijing and Several International Megacities
High-Efficient traffic system is very important for economy and society of c ities. Previous studies on the traffic comparison mostly took a city as a whole, but ig nored the differences among areas inside the city. But in fact, the traffic congestion in different areas with a city is mostly different. Taking typical megacities like Beijing, London, New York, and Tokyo as objects, this paper ma...
