摘要:
对交通出行者分类,并将路段、路口以及各类出行者分别指定为相应的agent,利用multi-agent方法和swarm仿真平台,通过规则设计,构造出较合理的抽象的宏观城市仿真系统.利用该仿真系统进行三组实验:出行规模实验、出行者实验、路网结构实验,对比分析不同微观组成的城市交通系统在仿真实验环境下的演化过程,从系统规模、系统结构两方面,发现并说明了城市交通系统中存在的缘自于微观机理的宏观现象,并指出了其中可能属于涌现范畴的现象.
Abstract:
Based on the multi-agent approach and the swarm platform, a macroscopic simulation of urban transportation system is developed. In the simulation, travelers are divided into three groups first, and then links, intersections and travelers are treated as agents respectively. Three different experiments, namely traveling scales, traveler groups and network structure experiments, are carded out by the simulation. Through comparing and analyzing the simulation results from the perspectives of system scale and structure,we try to find and explain the macroscopic phenomena and the possible emergence phenomena coming from the microscopic level in urban transportation system.
