Transportation engineers and planners develop and use forecasts of transportation demand in the design and analysis of transportation infrastructure and related transportation policy. This proposed research seeks to improve the mathematical models of spatial economic systems that can be used in such forecasting, enhancing the representation of the transport, land use, economic and environment components and their interactions. It concerns the nature of the actual behaviour of these components and the development of mathematical models representing this behaviour. The more specific intentions are to: - develop a better understanding of the behavioural processes involved, drawing on work in economics, geography and psychology; - identify model forms and approaches and related computational processes that improve the fidelity and policy responsiveness of such models; - identify processes in the development and calibration of such models that will help improve the results; and - eventually, bring about more wide-spread use of these models in practice. Currently, spatial economic models are used in only a relatively few locations and contexts - but the extent of use is starting to increase, in part as a result of the work done by the proposer. If the anticipated improvements help make these models better and thereby bring about increased use of these models in Canada and around the world, then there could be dramatic improvements in the manner that agencies take into account land use, transport, the economy and the environment in their planning, which ultimately has the potential to alter our entire quality of life for the better.

交通工程师和规划师在设计和分析交通基础设施和相关交通政策时开发和使用交通需求预测。这项拟议的研究旨在改善可用于这种预测的空间经济系统的数学模型，提高交通，土地利用，经济和环境组成部分及其相互作用的代表性。它涉及这些组件的实际行为的性质和代表这种行为的数学模型的发展。 更具体的意图是： - 利用经济学、地理学和心理学方面的工作，更好地了解所涉行为过程; - 确定模型形式和方法以及相关的计算过程，以提高这些模型的保真度和政策响应能力; - 确定有助于改进结果的模型开发和校准过程;以及 - 最终，使这些模式在实践中得到更广泛的应用。 目前，空间经济模型只在相对较少的地点和背景下使用-但使用的范围正在开始增加，部分原因是提议者所做的工作。如果预期的改进有助于使这些模型更好，从而使这些模型在加拿大和世界各地的使用增加，那么各机构在规划中考虑土地使用、交通、经济和环境的方式可能会有巨大的改进，最终有可能改善我们的整体生活质量。
