Simulation of Traffic Flow Model with Traffic Controller Boundary
This paper considers a fluid dynamic traffic flow model appended with a closure linear velocity-density relationship which provides a first order hyperbolic partial differential equation (PDE) and is treated as an initial boundary value problem (IBVP). We consider the boundary value in such a way that one side of highway treat like there is a traffic controller at that point. We present the ana...
متن کاملModeling and Numerical Simulation of Cellular Automation Traffic Flow Model
In recent years, the traffic is developing rapidly in China, the transportation is more and more convenient, but the traffic safety problem has become the focus problem in public life. Study of the traffic problem, which is beneficial to strengthening our country citizen's traffic safety consciousness, reduce the number of traffic accidents, so as to promote the development of transportation in...
متن کاملNumerical Simulation of Drift-Diffusion Traffic Flow Model
In this study, we present a numerical scheme to solve the drift-diffusion traffic flow model under the steady state. The drift-diffusion traffic flow model consists of a continuity equation and a nonlinear Poisson equation. The continuity equation describes the propagation of density along the road, and the Poisson equation describes the interaction among vehicles. The system equations cannot b...
متن کاملDecomposition of a Traffic Flow Model for a Parallel Simulation
With advent of Intelligent Transportation Systems (IST), it is required that the observation and control of traffic demand and flow be performed in real-time with more accuracy and reliability than before. In order to accelerate the traffic flow simulation the paper presents an algorithm for the decomposition of a mesoscopic traffic flow model for a parallel implementation on multiprocessor har...
متن کاملSimulation Models of Traffic Flow
This paper reviews the range of traffic models, with particular attention to microsimulation. Although there are major types, there are so many hybrids that it is difficult to classify them all. The standard way of assigning traffic to a network is to find a static equilibrium from which no driver would be able to find a quicker route. This gives fairly good predictions of the link flows result...
