It has long been recognized that urban transportation systems and built form are fundamentally intertwined: the transportation system provides access to land, thereby making it usable and helping to shape the distribution, types and densities of activities over space, while the built form and its associated spatial distribution of activities generates the demand for transportation services and the performance of the transportation system through the loading of this demand onto the road, transit and active (walk/bike) networks. The various adverse, “unintended” impacts of urban transportation systems (congestion, pollution, greenhouse gas emissions, accidents, etc.) are not solely the product of the transportation system, nor are “solutions” to these problems solely achievable through transportation system improvements. The way in which we build our urban regions is a fundamental determinant of transportation system performance, and more sustainable urban regions will require a coordinated and systematic redesign of both our built form and transportation systems. Recognition of this fundamental transportation – land use interaction directly implies the need for comprehensive, integrated models of transportation and land use that capture the two-way interactions between the two systems and that thereby allow the full impacts on an urban region of both transportation and land use policies to be systematically explored. With over 80% of Canadians living within urban regions, integrated urban models offer the potential to provide robust, credible forecasts of policy impacts to support improved, evidence-based decision-making concerning transportation and land use investments and policies. Given the billions of dollars that are expected to be spent in the coming decades on transit systems alone in this country, along with the serious challenges faced by our cities to remain high quality homes for our population in the face of continuing growth, such improved decision support tools can play a key role in finding cost-effective, sustainable paths into the future for our metropolitan regions. The Integrated Land Use, Transportation, Environment (ILUTE) model system is a state-of-the-art agent-based, integrated microsimulation model of urban spatial socio-economic processes (demographics, housing markets, travel, etc.). An operational prototype has previously been developed by the research team. The primary objective of the proposed research is to complete ILUTE as a fully operational tool for urban systems modelling and policy analysis. In addition to the development and deployment of this “ILUTE Version 1”, a second, longer-term objective of this research project is to begin work on the design of an “ILUTE 2.0” that is based on a strong, consistent theoretical framework, and new, emerging computational capabilities, datasets and modelling methods. This “2.0” design work will proceed in parallel with the “1.0” implementation. It will not result in an operational “2.0” system within the lifetime of this project, but it will lay the foundation for future work in this direction.

长期以来人们已经认识到，Urbansportation Systems是从根本上交织在一起的：运输系统o土地，活动的分布，分布，类型和密度在太空中，活动的空间分布活动的运输服务需求和运输系统的性能将该需求加载到上道路，过境和活动（步行/自行车）网络。各种不利的城市运输系统（拥塞，污染，温室气体排放等）的“意外”影响不仅是运输系统Solems可以通过运输系统改进来实现的问题。 认识这种基本运输 - 土地使用互动直接意味着需要捕获这两个系统的全面，离子和土地使用，允许对Urbansporta的影响和土地使用政策进行系统的探索。在城市地区，加拿大人的政策可靠地预测，以支持改进的，循证的，基于证据的决策和土地利用投资者和政策。在持续增长的过程中，这种改进的决策支持工具可以在为我们的大都市地区寻找经济高效，可持续发展的道路方面发挥关键作用。 综合土地使用，运输，环境（ILUTE）模型系统是城市空间社会经济过程（人口统计学，住房市场，旅行等）的最先进的综合微观化模型。根据拟议的研究的主要目的，是为城市系统建模和政策分析汇编Ilute asas onal。 除此之外，这是基于强大，一致的理论框架以及新的，新兴的计算能力，数据集和建模方法的“ Ilute 2.0”的第二个长期目标。
