Lately the computation of emissions has become more crucial. The level of emissions of traffic can be determined making use of simulation models, to check out ex-ante the effects of certain measures. The majority of the appropriate models are microscopic simulation models.
With an increasing number of highway traffic jams the interest in simulations of traffic flow is rising. Some models, which have been correlated with measured data, point towards the fact that the formation of congestion on a highway behaves like a phase
