摘要: |
将元胞自动机的演化与交通规则相联系,建立元胞自动机交通流模型,研究由快慢双车道组成的交通系统当两车道的车辆密度不对称时所引起的系统交通流特性的变化.计算机数值模拟结果表明:在不同的初密度分布条件下,双车道模型旱现出无耦合的自由运动相、有耦合的自由运动相、有耦合的两道各为局部阻塞相与畅通相的混合相以及无耦合的局部阻塞相等各种自组织行为. |

Abstract: |
The character of the traffic system which composes of fast-lane and slow-lane is investigated using a model for cellular automation traffic flow in terms of the combination of the evolvement of cellular automation and traffic regulations. The computer simulation indicates that the following self-organization phenomena, which are non-coupled and coupled free motions, traffic jam and non-traffic jam in the part of each lane of the coupled two-lane and traffic jam in the part of the non-coupled two-lane, would take place in the two-lane traffic model when initial densities are different. |
Key words: cellular automaton traffic flow model coupling effect |
