ABM与GIS集成及在分析新能源汽车扩散中的应用

Integration of ABM and GIS and its application in analysis of diffusion of alternative energy vehicles

新能源汽车及其加能站的扩散是多种主体相互作用的复杂过程.现有的分析该过程的基于agent的模型没有考虑现实的路网结构和驾车者行驶路线的分布,不能为具体某一城市或地区新能源汽车的推广提供决策支持.本文探索了一种集成ABM(基于agent的建模)与GIS(地理信息系统)的技术实现方法,其核心思想是利用Repast仿真框架对图形文件的读写接口,建立其与ArcGIS间的通信,形成一种松耦合的、基于矢量的集成方式.应用该集成方式,本文以上海市为例构建了基于城市路网结构的新能源汽车及其加能站交互扩散的仿真平台.

The diffusion of AEVs （alternative energy vehicles） and their refueling stations are a complex process involving various actors interacting with each other. Current agent-based models for analyzing this process did not eonsider the real road networks and the distributions of the driving routes. This paper explores a technical solution for the integration of ABM （ agent-based modeling） and GIS （geographic information sys- terns）. The core idea of the solution is establishing communications with ArcGIS （ a popular GIS software plat- form） by using Repast （ a popular ABM simulation software platform）＇ s interface to shape files and thus a vec- tor-based loose coupling is realized. With this solution, a simulation platform was developed to study the co- diffusion of alternative energy vehicles and their refueling stations based on the real road networks, with Shang- hai as an example for simulation.
