| 摘 要： | 该文从研究城市交通系统中个体的空间行为特征出发，开发城市交通管理虚拟实验系统(VLUTM)，该系统利用GIS管理城市交通系统的空间数据，用Multi-Agent System模拟城市交通系统中个体的空间行为。VLUTM引入最佳路径表实现动态最佳路径的快速检索；采用矢量一栅格形式表达城市道路；用Agent状态数据库记录个体在不同时刻的位置与状态。VLUTM供实验条件输入模块和实验结果分析模块，用户可根据实际情况自定义实验内容，可对实验结果进行可视化分析和指标分析。

| Abstract: | Based on the study of individuals' spatial behaviors,the author developed a virtual laboratory system for urban traffic management (VLUTM).VLUTM employs GIS to manage the spatial data of urban transportation system,and Multi-Agent System to simulate the actions of individuals.In VLUTM,the best route table is applied for a quick query of the dynamic best-route;the vector-raster format is adopted to describe the urban roads;and Agent status database is used to record the individuals' locations and statuses at different time point.By utilizing the input module of simulation condition,user can customize the experiment content based on the realities.By utilizing the simulation results analysis module,user can assess the simulation results by different indexes,or visualize the simulation process by a graphical interface.In addition,this paper presents an example for a further discussion of VLUTM.The study shows that VLUTM will be an effective virtual laboratory system for urban traffic management. |
