提出了带有偏置随机游走器的晶格气体模型，以模拟恒定密度开放边界条件下通道中的行人逆流。没有后退一步的步行器有两种：一种是向右的随机步行器，另一种是向左的随机步行器。研究发现，在临界密度处会发生从低密度的自由移动状态到高密度的停止状态的动态干扰转变。转变点由 p(c) = 0.45 +/- 0.01 给出，不取决于系统规模。转变点取决于漂移的强度，并随着漂移的增加而降低。此外，我们提出了扩展模型，以考虑行人最好在通道右侧行走的交通规则。 (C) 1999 Elsevier Science B.V. 保留所有权利。
A lattice gas model with biased random walkers is presented to mimic the pedestrian counter flow in a channel under the open boundary condition of constant density. There are two types of walkers without the back step: the one is the random walker going to the right and the other is the random walker going to the left. It is found that a dynamical jamming transition from the freely moving state at low density to the stopped state at high density occurs at the critical density. The transition point is given by p(c) = 0.45 +/- 0.01, not depending on the system size. The transition point depends on the strength of drift and decreases with increasing drift. Also, we present the extended model to take into account the traffic rule in which a pedestrian walks preferably on the right-hand side of the channel. (C) 1999 Elsevier Science B.V.
