项目摘要
Activity/tour-based models of urban travel demand are increasingly used in operational planning practice. These are generally implemented within an agent-based microsimulation (ABM) framework, in which out-of-home activity participation and associated travel are modelled for individual trip-makers (agents). ABM provides an extremely flexible, powerful and efficient means for modelling complex spatial-temporal, socio-economic behaviour such as travel. A leading example of such models is TASHA, which has been in operational use in the Greater Toronto Area (GTA) since 2016. The rapidly growing availability of "big data" concerning travel behaviour from a variety of sources, continuing growth in computing capabilities, and ever-changing (and increasingly challenging) policy analysis issues (autonomous vehicles, new mobility services, promoting active transportation, social equity concerns, etc.) create both the opportunity and the need to continue to develop more advanced, robust travel demand modelling methods to help guide the continuing explosive growth of urban regions worldwide along more sustainable paths. Current models represent "first-generation" ABMs. Considerable need and opportunity, however, exists for the development of significantly more powerful "second-generation" ABMs that build upon emerging big datasets (among other information sources) and High Performance Computing. To do so, however, will involve the development of new behavioural representations and computational algorithms, implemented within much more flexible software environments that both fully exploit available computing power and enable flexible experimentation with and extension of representations of new transportation modes and services and evolving travel behaviour. The objective of the proposed research is to develop such a second-generation ABM model system: TASHA/2. Building upon the proven base design of TASHA, the next version will address many of the weaknesses identified above. The research will be organized within 6 interconn
基于活动/旅游的城市旅行需求模型越来越多地用于运营计划实践中。这些通常是在基于代理的微观仿真(ABM)框架中实施的,其中为单个旅行者(代理商)对室外活动参与和相关旅行进行了建模。 ABM提供了一种非常灵活,强大和有效的手段,用于建模复杂的时空,社会经济行为,例如旅行。此类模型的一个主要示例是Tasha,自2016年以来一直在大多伦多地区(GTA)进行运营使用。关于来自各种来源旅行行为的“大数据”的迅速增长,持续的计算能力,持续增长以及不断变化的(越来越具有挑战性的)政策分析问题(自动驾驶汽车,新的出行服务,促进积极的运输,社会公平问题等)既创造机会又创造机会,又需要继续发展更高级,强大的旅行需求建模方法帮助指导全世界沿着更可持续的道路的城市地区持续的爆炸性增长。当前的模型代表“第一代” ABM。但是,存在着重要的需求和机遇,它是建立在新兴的大数据集(以及其他信息源)和高性能计算的基于更强大的“第二代” ABM的开发中。但是,为此,将涉及开发新的行为表示和计算算法,这些算法在更灵活的软件环境中实现,这些软件环境既充分利用可用的计算能力,又可以通过新运输模式和服务的表示和扩展来实验,并扩展了旅行的旅行。行为。拟议的研究的目的是开发这样的第二代ABM模型系统:Tasha/2。在塔莎(Tasha)的经过验证的基础设计的基础上,下一个版本将解决上述许多弱点。该研究将在6个互连内组织
