Phase transition in a directed traffic flow network.
The generic feature of traffic in a network of flowing electronic data packets is a phase transition from a stationary free-flow phase to a continuously growing congested nonstationary phase. In the most simple network of directed oriented square lattice we have been able to observe all crucial features of such flow systems having nontrivial critical behavior near the critical point of transiti...
متن کاملPhase transition in a difference equation model of traffic flow
A difference equation is presented to describe traffic flow on a highway. The difference equation model is derived from the optimal velocity models formulated in terms of the differential equations. It is compared with the differential equation models. We investigate phase transitions among the freely moving phase, the coexisting phase in which jams appear, and the uniform congested phase. The ...
متن کاملChaotic jam and phase transition in traffic flow with passing.
The lattice hydrodynamic model is presented to take into account the passing effect in one-dimensional traffic flow. When the passing constant gamma is small, the conventional jamming transition occurs between the uniform traffic and kink density wave flows. When passing constant gamma is larger than the critical value, the jamming transitions occur from the uniform traffic flow, through the ch...
متن کاملRegional Transportation Network Travel Time Estimation Based on Transition of Traffic Flow Phase
Travel time is widely recognized as an important performance measure for assessing transportation system, it is a meaningful parameter in theory and practice. Previous researches about travel time mainly focus on two areas: first, the research object is the unit of the transportation network, and there is little research on the area transportation network travel time; second, previous researche...
متن کاملAsymptotic Traffic Flow in a Hyperbolic Network: Non-uniform Traffic
In this work we study the asymptotic traffic flow in Gromov’s hyperbolic graphs when the traffic decays exponentially with the distance. We prove that under general conditions, there exists a phase transition between local and global traffic. More specifically, assume that the traffic rate between two nodes u and v is given by R(u, v) = β−d(u,v) where d(u, v) is the distance between the nodes. ...
