由忽视交通规则的代理引起的流量改善

Flow improvement caused by agents who ignore traffic rules

摘要:

一个系统的代理沿着道路在两个方向上移动数值研究内的细胞自动机制定。当遇到其他座席时,座席以概率$q$向右移动,或以概率$1-q$向左移动。我们的模型被限制为两种代理类型,交通规则遵守者($q=1$)和交通规则遵守者($q=1/2$)。交通流,从这两种类型的代理之间的相互作用,得到作为密度和相对分数的函数。当从无序的情况开始时,以固定密度堵塞的风险在每个代理人遵守交通规则时比所有代理人都忽略规则时要小。然而,绝对最小值发生在大多数遵守者中存在一小部分遵守者时。获得了流型空间结构的特征,并进行了讨论。

英文摘要:

A system of agents moving along a road in both directions is studied numerically within a cellular-automata formulation. An agent steps to the right with probability $q$ or to the left with $1-q$ when encountering other agents. Our model is restricted to two agent types, traffic-rule abiders ($q=1$) and traffic-rule ignorers ($q=1/2$). The traffic flow, resulting from the interaction between these two types of agents, is obtained as a function of density and relative fraction. The risk for jamming at a fixed density, when starting from a disordered situation, is smaller when every agent abides by a traffic rule than when all agents ignore the rule. Nevertheless, the absolute minimum occurs when a small fraction of ignorers are present within a majority of abiders. The characteristic features for the spatial structure of the flow pattern are obtained and discussed.
