The ILUTE Model

ILUTE is an integrated urban modelling system that consists of a "behavioural core" of the following four inter-related components:

Land Development
Location Choice
Activity/Travel
Auto Ownership

Each of these behavioural components involves a complex set of sub-models that incorporate supply/demand interactions, and interact among each other. For example, land use evolves in response to location needs of households and firms, and people relocate their homes and/or jobs at least partially in response to accessibility factors.

To build a comprehensive model that accounts for each of these behavioural components, the ILUTE project is modelling the actions of both persons and firms, since both of these actors make decisions that directly influence travel demand. Households are also modelled as a specific entity within the model because certain choices such as residential location and automobile ownership tend to be made at the household level, and there is usually a sharing of resources within a household which also contributes to shared household decision-making.

In modelling travel, ILUTE adopts an explicit activity-based approach, in which travel derives from the need to participate in activities, and the spatial temporal pattern of travel is the dynamic outcome of each person's activity scheduling/re-scheduling process.

The ILUTE model currently under development is a microsimulation model of the Greater Toronto Area (which will also be applied in other Canadian urban centres including Quebec City and Edmonton).
