【摘要】 实际观测表明,路边停车区泊车时的车间距分布符合高斯幺正系综分布,而道路交叉口红灯前车辆排队时的车间距分布符合高斯辛系综分布。文章探究了这两者的差别,并提出了一种基于马尔科夫链间距模型的解释。计算机仿真的结果表明,这个模型能较好的解释为什么在相似车辆运动情形下会产生2种不尽相同的分布;表明马尔科夫链间距模型可以广泛应用于交通仿真领域。更多还原

【Abstract】 According to the collected data,the spacing distribution of parking vehicles follows a Gaussian Unitary Ensembles(GUE) distribution,and queuing vehicles in front of signalized intersection follow a Gaussian Symplectic Ensembles(GSE) distribution.In this paper,a Markov-Gap model was proposed to explain and reproduce the phenomenon.The simulation gave a satisfactory explanation of why different distributions could be formulated in two similar situations.The results also indicate that Markov-Gap model could be applied in many other traffic simulations.更多还原
