Typically, networks representations of real systems are static, useful for generating descriptive network measures. However, recent interest lies in the representation and analysis of evolving spatial networks that can facilitate the examination of the close coupling between network structure and network dynamics. Therefore, this study proposes a novel spatial modelling framework, Geographic Network Automata (GNA), to represent evolving spatial networks as a function of iteratively applied transition rules. The framework is demonstrated using an adapted and spatially explicit version of Conway's Game of Life. The simulated spatial network structures are quantified using network measures. The presented GNA model framework is general and flexible so that different types of geospatial phenomena can be modelled, providing valuable insights into the link between network structure, dynamics, and evolution.","PeriodicalId":231488,"journal":{"name":"Proceedings of the 1st ACM SIGSPATIAL International Workshop on GeoSpatial Simulation","volume":"71 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121276379","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This presents a challenge both to those in the industry who wish to understand how they might adapt and change their ways of doing delivery and the policymakers who would like to encourage this in order to positively impact urban areas in terms of traffic and pollution. We present an early implementation of an agent-based modelling framework of parcel delivery processes, flexible enough to be extended to explore a variety of scenarios. We apply it to a baseline case study to begin the process of exploring the effectiveness of switching to a different method of delivery.","PeriodicalId":231488,"journal":{"name":"Proceedings of the 1st ACM SIGSPATIAL International Workshop on GeoSpatial Simulation","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130518770","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
