Continuum Traffic Simulation

Continuum Traffic Simulation

We present a novel method for the synthesis and animation of realistic traffic flows on large-scale road networks. Our technique is based on a continuum model of traffic flow we extend to correctly handle lane changes and merges, as well as traffic behaviors due to changes in speed limit. We demonstrate how our method can be applied to the animation of many vehicles in a large-scale traffic net...

Continuum Modelling of Traffic Flow

We wish to consider the problem of modelling flow of vehicles within a traffic network. In the past, stochastic traffic models have been developed [13, 8] in order to investigate a wide range of traffic configurations. However, if the population is sufficiently large, these stochastic processes tend towards a continuum approach. Consequently, this approach is most useful when considering long, ...

An improved second-order continuum traffic model

We construct a second-order continuum traffic model by using an iterative procedure in order to derive a constitutive relation for the traffic pressure which is similar to the Navier–Stokes equation for ordinary fluids. Our second-order traffic model represents an improvement on the traffic model suggested by Kerner and Konhäuser since the iterative procedure introduces, in the constitutive rel...

Multiscale gas-kinetic simulation for continuum and near-continuum flows.

It is well known that for increasingly rarefied flow fields, predictions from continuum formulations, such as the Navier-Stokes equations, lose accuracy. The inclusion of higher-order terms, such as Burnett or high-order moment equations, could improve the predictive capabilities of such continuum formulations, but there has been only limited success. Here, we present a multiscale model. On the...
