摘要
According to the empirical observation of highway traffic, inside wide moving jams there is a complex spatiotemporal structure: jam is not compact and relatively large values of the time and the distance headway are visible. We present a cellular automata model by introducing "jam headway" and "jammed status" to simulate that complex structure. Using computer simulations, the fundamental diagram, the space-time plots, the time series of the density in the jams, and the 1-min average data of this model are analyzed. It is shown that compared to other existing models, this model can display the experimental characteristics of the wide moving jams.
