| 摘 要： | 通勤是人们周期性往返于居住地与工作地之间的行为,研究城市居民的通勤过程有利于分析高峰时期的交通拥堵问题并为制定相应解决方案提供依据。为此,本文提出了一种基于多智能体的交通仿真框架,包括乘地铁和公交车两种主要的公共交通出行方式。论文重点讨论了利用职住数据模拟交通过程的方法,首先,根据居民的居住地与工作地构成的OD(起止点)矩阵为其分配路径,然后利用提出的框架进行交通仿真,最后基于仿真结果统计需要的交通特征。论文以深圳市为例进行试验,结果表明,提出的方法能较好地模拟居民通勤行为的过程和统计交通流大小等特征。

| Abstract: | Commuting refers to the behavior that people travel between homes and workplaces periodically. The research on the commutingprocess of urban residents is advantageous to the analysis of traffic jams during rush hours,which can provide supports for devising accordingly solutions.A multi-agent based framework is proposed in this paper,including two major public transportation travel modes of taking subway and bus.The method of simulating the traffic process by using the homes and workplaces data is focused on.First,assigning routes for citizens according to the OD matrix constructed with their homes and workplaces.Second,executing the traffic simulation using above framework.Third,extracting traffic features from simulation results.Shenzhen is taken as a case city and the result shows that the proposed method can accurately simulate the citizens' commuting behaviors and acquire significant traffic parameters. |
