Numerical investigation of a mesoscopic vehicular traffic flow model based on a stochastic acceleration process

In this paper, a spatial homogeneous vehicular traffic flow model based oil a stochastic master equation of Boltzmann type in the acceleration variable is solved numerically for a special driver interaction model. The solution is done by a modified direct simulation Monte Carlo method (DSMC) well known in nonequilibrium gas kinetic. The velocity and acceleration distribution functions in stochastic equilibrium, mean velocity, traffic density, accelerated noise (ACN), velocity scattering and correlations between some of these variables and their car density dependences are discussed.
