A Second-Order Lagrangian Macroscopic Traffic Flow Model for Freeways
A macroscopic traffic flow model describes the evolution of aggregated traffic characteristics over time and space, which is a basic and critical component for various modern intelligent transportation systems, e.g., a real-time freeway control system. Traditional macroscopic traffic flow models are built in the Eulerian coordinates using Eulerian traffic characteristics, such as density, speed...
متن کاملMacroscopic dynamics of multilane traffic.
We present a macroscopic model of mixed multilane freeway traffic that can be easily calibrated to empirical traffic data, as is shown for Dutch highway data. The model is derived from a gas-kinetic level of description, including effects of vehicular space requirements and velocity correlations between successive vehicles. We also give a derivation of the lane-changing rates. The resulting dyn...
متن کاملA Multiphase Model for Macroscopic Traffic Flow
The main differences between the deterministic macroscopic models stand in pressure expressions and representation of various phases observed experimentally. Starting from two assumptions, we build a multiphase model that represents macroscopic traffic flow on a single road. The conditions for transition between phases become clear. In addition, a simulation of some scenario are proposed to sup...
متن کاملUnsteady Magneto Hydro Dynamic Flow of a Second Order Fluid over an Oscillating Sheet with a Second Order Slip Flow Model
Unsteady slip-flow of second grade non-Newtonian electrically conducting fluid over an oscillating sheet has been considered and solved numerically. A second-order slip velocity model is used to predict the flow characteristic past the wall. With the assumption of infinite length in x-direction, velocity of the fluid can be assumed as a function of y and t, hence, with proper variable change pa...
متن کاملA first order model in traffic flow
First order traffic flow models have been studied for long time, since they represent the simplest way to begin with the understanding of such a complex system. To our knowledge the Lighthill-Whitham-Richards (LWR) model was the first model to describe unidirectional, one-dimensional traffic flow in a highway [1], [2]. This model considers the continuity equation for the density of vehicles (nu...
