In many Canadian cities, strong economic growth and rapidly changing socio-demographic structures are creating enormous pressure on urban transportation systems. Such situations demand proper maintainance of exististing transportation systems and also building new transportation infrastructures. In order to maintain existing systems efficiently and develop new infrastructures sustainably, we need analytical models that can predict the evolution of demands for urban transportation in future. Existing state-of-the art model, known as activity-based travel demand model fails to replicate complex travel patterns over a short-term time period. It is necessary to develop a new methodology for activity-based travel demand model that can replicate reliably the evolution of peoples' activity/travel patterns over short- to medium- and long-term time periods.

在加拿大的许多城市，强劲的经济增长和迅速变化的社会人口结构对城市交通系统造成了巨大的压力。这种情况要求适当维持现有的运输系统，并建立新的运输基础设施。为了有效地维护现有系统并可持续地开发新的基础设施，我们需要能够预测未来城市交通需求演变的分析模型。现有的最先进的模型，即基于活动的旅行需求模型，无法在短期内复制复杂的旅行模式。有必要开发一种基于活动的旅行需求模型的新方法，该模型可以可靠地复制人们的活动/旅行模式在短期到中期和长期期间的演变。
