摘要: 交通拥堵问题困扰人们由来已久。为了探究道路行驶中突发状况限制车辆行动速度会对道路行车状态造成的影响，建立边界处粒子的跳跃率不同的ASEP模型，探究跳跃率的改变对系统内粒子流量与粒子密度造成的影响。模型分为入口、出口两种情况，在特定取值下系统稳态MC相将会消失。此外由于跳跃率p增加分别会使两种情况下模型内粒子密度减少或者增加，利用计算机模拟粒子运行过程、蒙特卡洛算法进行数据统计，获得结果与理论值一致。
Abstract: The problem of traffic jam has been a long time. In order to explore the impact of the traffic speed on the road traffic condition, it is necessary to explore the emergency situation in the road. A dif-ferent ASEP model was established to investigate the effect of different jump rates on particle flux and particle density in the system. The model can be divided into two situations: entrance and exit. The steady-state MC phase will disappear under certain values. In addition, because the hopping rate p increased by two kinds of cases within the model to reduce or increase the particle density, operation process, the use of computer simulation of particles for statistical Monte Carlo algorithm, the results are consistent with the theoretical value.
