Enskog-like Kinetic Models for Vehicular Traffic

In the present paper a general critisicsm of kinetic equations for vehicular traac is given. The necessity of introducing an Enskog-type correction into these equations is shown. An Enskog-like kinetic traac ow equation is presented and uid dynamic equations are derived. This derivation yields new coeecients for the standard uid dynamic equations of vehicular traac. Numerical simulations for in...

Enskog-like discrete velocity models for vehicular traffic flow

We consider an Enskog-like discrete velocity model which in the limit yields the viscous Lighthill-Whitham-Richards equation used to describe vehicular traffic flow. Consideration is given to a discrete velocity model with two speeds. Extensions to the Aw-Rascle system and more general discrete velocity models are also discussed. In particular, only positive speeds are allowed in the discrete v...

General kinetic models for vehicular traffic flow and Monte Carlo methods

In this paper we present a general derivation of kinetic models for traffic flows including different kind of interaction rules. We show that most kinetic models previously derived can be cast in the actual formulation. The development of Monte Carlo methods for direct simulation of the kinetic models is considered as an initial step towards realistic and efficient computations of traffic pheno...

On the mathematical theory of vehicular traffic flow II discrete velocity kinetic models

This paper deals with the modelling of vehicular traffic flow by methods of the discrete mathematical kinetic theory. The discretization is developed in the velocity space by a grid adapted to the local density. The discretization overcomes, at least in part, some technical difficulties related to the selection of the correct representation scale, while the adaptative grid allows an improved de...

Continuous Time Stochastic Models for Vehicular Traffic on Highways

We have simulated a continuous time version of the Nagel-Schreckenberger model of vehicular traffic on highways and calculated the flux as a function of vehicle density. In the low density regime the flux increases linearly with density but becomes a power law when velocities are allowed to increase without bounds. We have simulated also a modified version in which the state of a vehicle depend...
