摘要:
针对de Moura等人提出因特网信息流的费米-狄拉克统计模型,我们提出用玻色-爱因斯坦统计模型来研究一般交通客运网络中的客流分布问题.将交通客运网络抽象成一个与外界有粒子和能量交换的热力学系统,其中粒子代表乘客,适当地定义能级,分析得出交通网络中的每个站点平均客流的解析表述.然后以中国铁路客运网络实际拓扑为基础,用随机行走模型模拟分析交通网络中的客流分布情况,模拟结果显示,无论初态如何,经过足够长时间后,各站点的客流分布趋于平衡,平衡时各站点的客流量与其点权正相关,模拟客流分布曲线与理论结果基本一致.
Abstract:
Com pa ring w ith deM oura. s m ode l o f Ferm -iD irac sta tistics fo r traffic in a ne tw ork, we stud ied the statistical properties o f the genera l passeng er transpo rt netwo rk w ith Bose-E inste in d istr ibu tion. A transport o f passenger netw ork can be modeled as a therm odynam ics system exchang ing partic les and energy w ith its env ironm ent, w he re passengers are considered as particles. W ith appropr iate ly de fined energy- leve l struc ture, the ana ly tica l expressions of the passenger flow of the transpo rt netwo rk can be ob tained. Based on the emp irical prope rties o f Ch inese ra ilw ay netwo rk, we propose an idealized m ode,l in which larg e numbers of passengers move random ly from one sta tion to another in th is ra ilway ne-t w ork. Num e rica l s imu lations show tha t whatever the ear ly state is, in the ty ] lim it the netw ork reaches a sta tionary sta tew ith the passenge r flow in propo rtion w ith the nodewe ight. The num erical simu lations resu lts are shown to be nearly in ag reem ent w ith the ana ly tica l expressions.
